I’m pretty sure I have one too as I lost one awhile back and purchased two new ones. I’ll have to find it first in the garage. I also have extra new flying “R” decals.

i would take them as the old ones are getting pitted

I have one. Please measure the diameter to be sure mine will fit. I can shop it to you tomorrow if it is the correct size.

about 8" 9/16 ID, depending on price I might take 2?

lost on on 95 somewhere on way home in February, would like to replace with original if anyone has one kicking around.

Thanks

Bill

if you still have them I am interested in couple of drawers, couple of door shelves and the black trim that holds panels on freezer doors,

Thanks

It just so happens that I have the norcold cooling setup that I removed to install the jc refrigeration unit. First $100 plus shipping gets it.

Is that Amish unit or norcold

I know the information won't be available anywhere, but would be interesting to know the DOT date code of the tires.  Only one item to consider, obviously inflation pressure, load, load rating, etc can be a contributor, but running tires past their useful life seems to be a common issue.

Would like to see the data to support your theory

Unfortunately this accident happened to a customer of ours. They were on their way to our facility for some service work.

He is a member here and has been a friend of mine for several years. He contacted us immediately after the accident. I am not going to get into specifics but he is a very conscientious owner who looks after his coach and pays attention to details. I did get an updated message from him yesterday and his wife did survive and will recover. He also is OK.

The coach is obviously destroyed. There is a lot of back story to this coach that I wont get into but I was called as an expert witness to testify on his behalf after a dealer completely screwed the coach up. Due to my testimony the dealers insurance company settled. He was on his way to our facility to get some final work done. I find it a shame that now the coach is totaled. This was their home as they were full timers.

On a positive note I am thankful both of them survived. It is a testament to how well our Monaco coaches are built. In regards to anything else related to this accident I am not going to comment. I know the owner very well and I can tell you he would never risk himself or his wife with old tires, fast driving or anything that would contribute to an accident. Even new tires blow and I witnessed an HR Imperial have a double blow out on new tires that had less then 500 miles on them. The only thing I will say is if you don't have Tyron bands on your coach...........Get Them.

Please keep this couple / fellow member and his wife in your thoughts and prayers.

Great information and should sooth the aged out, off shore, cheap owner  theorists who are so quick to blame old or foreign tires as the culprit,

Ward,

Sorry to hear about your TST issues. The information you were told is not something our Tech Department would say so I am confused as to who you spoke with. Are you sure it was TST or possibly one of our dealers (like Techno RV)? None of us would tell you to put the repeater in the battery compartment. That is a Faraday Cage and the repeater will not work in there. Moving the display to the other side of the dash will not solve interference issues. None of the suggestions sound like anything one of my Techs would tell you. Very odd. Wish I had talked with you. Sorry for the issues. I believe they could have been resolved.

Also...Bob...Putting any repeater in the back wardrobe, if it has mirrors in front of it, is also a Faraday Cage. You may not get good results from that repeater placement.

Been round and round with TST on this with the well known TST reps that post on this forum who requested not to be mentioned by name. They (TST officials) would not stand behind the product and send equipment that functions, instead insisting that I must BUY a new display at a "discounted" price from them that was actually a HIGHER PRICE than one could purchase new from other online sources cheaper.  At one time they might have sent functioning equipment, but as I got a little over two years of a usually "working" product before having the well known rep explain to me the design change that causes the failures, they wouldn't support the product as it was "time to buy an upgrade" in their eyes. You got lucky if you got support from TST.

FWIW, YMMV, just my actual experience and facts

Al

 

As stated, been with TST for at least 12 years, they have replaced defective sensors, they exchanged flow through for capped sensors when I expressed concern about how far flow through stuck out past rim on car hauler, sent o rings when I encountered leaks after replacing batteries and replaced all caps on flow through when they were bending after replacing batteries,  so fwiw they have been a stand up company and as far as I’m concerned do put safety first, and most importantly I have confidence in the tpms and thats more important than anything because it works

A little more history of the design failures of the TST product.

In 2020, Jim (of TST) publicly stated TST made a design change in 2015 that would break the existing systems.  Potential future failures unbeknownst to me, in the spring of 2016 I researched systems and after talking with Mike B (also of TST) made what I thought at the time was a good choice and go with the TST-507 and not wait for the color monitor as color can be hard for me read.  No clue from TST the system I was purchasing AFTER the internal design change was going to have a design issue.  A design change was never ever mentioned!  The system worked very well for a while, then I noticed a couple instances of these seemingly random high pressure alarms on the way back from the boonies of Newfoundland in 2018.  Figuring batteries were going out I replaced them.  But traveling season was basically over and the rare failures dropped from my radar as the coach was parked. In 2019, my system worked up in the boonies of Alaska but upon returning to the lower 48 I started getting false alarm failures more often.  Again no clue that TST had broken my system.  If the antenna had broken off, or display went black I would assume just normal use wear and tear failure and oh well things happen.  I did have one flow thru sensor case crack and develop a slow leak, but I wrote that off as things happen and just bought a new one.  But to find out TST KNOWS and acknowledges they broke my system is another thing, and they make no reasonable attempt to make it right is just not right.  With them ignoring their problem I have to wonder if indeed it was planned systemic obsolescence.  Given what Jim says is only a few affected units, I'm sure their cost to ship a unit correcting the design issue is less than the time Jim wastes reading this, or hearing feedback from seminars/rallies/campfire chats where this problem is and has been easily demonstrated and discussed.  Instead they want their customers to buy a fix that isn't the customer's fault.  When my system works, it functions great and I will readily say so.  When it gives false high pressure alarms it is not so great.  In the past I have dealt with many other companies that do the right thing.  So far it appears TST's corporate culture is different.

I am glad for all of you that have functional (at least for now) TST-507 systems.

Had same problem, explained it in an email to TST, they air freighted new display to me within days, NO CHARGE, problem solved. Been a customer for over 12 years, have flow through with repeater on coach, non flow through on trailer, had couple of sensors leak after battery replacement, likely my fault, system has saved me major problems several times, detecting and warning of punctures, leaking valve stems and even hot bearing on trailer. Great customer service and great system

Al, the TST system can be programmed very easily for high and low pressure readings.  Just reprogram it and the high pressure alarms will go away.  Before we leave in the morning I turn on the system and in less than 5 minutes all readings of pressure are available on the monitor, including the toad.

Same here

Do you have a tag axle?

85psi is what the manufacturer calls for in the drive axle tires on our tag axle coach.

I do yes, drive tire actual weight calls for 95 psi in dual tire application, 

4 minutes ago, Roger 2006 HR Endeavor PDQ said:

We need to be careful with terminology on this topic.

The first thing you need in order to set pressures correctly is the weight on each axle end (not tire position). All four tires on the drive axle should be inflated to the same pressure as determined by the weight of the heavier axle end. The same principle applies to the steer and tag axles; tires on both axle ends should be inflated to the pressure required for the heavier end. The two (or three) axles may very well have different pressures. No to worry. Properly inflated, each axle will be able to carry its load safely.

Getting the tire pressures right does not make your tires blow-out proof. There are still road hazards (pot holes, road debris, etc.) that can inflict great damage.

Safe Travels,

I think you meant to say tire position as that means each axle end, ie: drive left or right and tag left and right, steer left and right, little confusing for those new to the hobby. 
 

As far as tpms, you are right tpms won’t stop debris, tire damage from any number of road hazards, but typically damage creates low pressure or occasionally high pressures, or measurable increases or decreases in pressures or temperatures,  and those factors are what tpms warns of, under inflation is still number 1 killer of tires and tpms greatly decreases likelihood of blow outs due to under inflation caused by punctures or damage.

Lots of good advise here, I’ve been using TST for 12 years, well worth the expense and I highly recommend, I use 8 flow through on coach and 4 non flow through on car hauler with a repeater. system has detected several minor leaks and even hinted at bearing problem on trailer which proved to be minor but  needed correction. Weighing all 6 positions on the coach is recommended, this allows running lowest safe pressure for each axle which should be based on heaviest weight per axle. Same Pressure across axle. I have found steer tires typically require highest pressure cold. Followed by drive and tag. I have extenders on inner drive axle only, they have not leaked on 10 years. As far as other maintenance, welcome to the club, if you were hoping for plug and play,  get out of the motor coach game,

The Cummins ISM 500 and Allison 4000 are rock solid.  Some of the 2003 and newer ISM engines had an occasional EGR cooler failure.  

You may want to reconsider using Rotella T6.  These engine require 10 gallons (not quarts) of oil and run great on Rotella T3.  In fact, Cummins recommends conventional oil.  

How many hours on the generator?  The early Onan 12.5 generators have an Isuzu 3 cylinder engine that is also rock solid.  When they reach 2000 hours most will recommend a belt change and the belt is buried in there.  

The rest of the coach will keep you very busy repairing and updating systems but these are great coaches.  

Best of luck!

thanks, plenty of experience with older dynastys,, labour of love

Had a few coaches with ISC 8.3 and ISL Cummins 8.9 with Allsion 3000's and 7500 Onan QD's had great luck so far, looking at a Signature with ISM 500 and Allison 4000, 120000 miles on coach, what am I in for and are there any known problems with either I should be aware off. I typically ensure trannys have life long filters and transynd, always run Rotella T6 oil 15\w\40 in motors and genny,  Not sure of Onan 12500 hours yet, any issues with these that anyones aware off?  

Thanks

I really wish some of the ego's would diminish. 

 

True that, 

When you have been at this long enough which a few of us have, you start to get an idea of what works. I’ve been at it for more than 25 years, most of those years at the helm of a pusher, 10 years with a tag. When I started out I read a lot and asked questions, always tried to err on the side of safety. 
 

Here’s what I know, a few times my TPMS has saved me, couple of slow leaks, few foreign objects getting in my tires and couple leaking valve stems. The TPMS actually picked up a bad trailer bearing and prevented significantly more damage and time spent on the side of the road. So i am a believer in TPMS. I also carry an infrared thermometer, if any tire seems to be higher than surrounding tires it’s usually heat, could be tire, could be bearings, excessive speed or brakes, with thermometer you can narrow it down quickly. Ive weight coach several times and set pressures to highest weight on any axle. Never drive over 65 - 67 mph to keep coach and trailer tires in their window of operation. 
 

You look after your tires, use them as they are meant to be used and take proper precautions they will look after you and your trips will be far less stressful. 
 

To those new to these incredibly complex machines, there is a wealth of information on this site, there is also some hot air, but all in all, mostly sound advise

Education is key

You are worried about the starting cold psi difference but won’t spend the $15 to weigh your axles at a truck stop to know where to start from?
You posted you had a 20-30 psi increase in a rear tire which tells me it was under inflated to start with… 15% increase is normal but not 25+%. Go weigh your rig!

Good advise

I'm pretty sure that every tire made in the last 50+ years has a max inflation figure imprinted into it, lawnmower, bicycle, heavy equipment, passenger cars, whatever...

In all those cases, max inflation number on the tire has nothing to do with the pressure we need to be inflating them to... Doesn't matter if it's a riding mower or a semi truck, there's a specified inflation pressure and it's not based on what's printed on the sidewall...

Cheers,

Walter

Agreed

I am running Toyo M144 295/80R/22.5 on my 2012 Diplomat 43DFT.  Fronts are set at 105 and drive and tag are at 85.  I am also using the TST TPMS.

I drove back from the Tampa Gathering last week.  The ambient temp was around 60-70 for most of the first day drive.  Pressures rose to 125 and 100.  I was surprised that the pressures went up that much.  The second days was raining and in the 40’s.  Temperatures did not increase as much, but still rose between 10 and 15 PSI.

 

Seems about right, I run my drive at 95, you my be slightly low on drive, adding 5 lbs, your cold temps could be low depending on what scale says

I always use the local temp as the ambient temp to set my Cold psi pressures to.

Such as we are starting this trip in the morning with outside ambient temps around 40F

I have set the front tires at 110 psi, the dual drive tires at 95 psi and the tag tires at 85 psi.

We are driving south into warmer weather, but I won't do any adjustments until possibly sometime later in my trip back to Florida.

I don't mind the tires increasing pressure somewhat when moving into warmer weather as that provides a good safety factor. However, when moving from hot weather into really cold weather I always adjust the cold psi back up to where it belongs.

Did same thing in December, only adjusted steer tires down. -15c when I left by the time I got to warm weather steers we’re almost 130 warm I let 5 lbs out next morning

I have decided not to purchase the Coach-Net Tire & Wheel Hazard Protection package for the cost of $1224 for 5 years.

Instead, I plan to use that money to purchase two new steer Toyo Tires M144 size 295/80R/22.5 plus a pair of Balance masters from Josam's in Orlando once I return back home to Florida.

Sometime later in the year prior to heading north for the summer I will have Josam's install four new drive Toyo Tires M144 295/80R/22.5 with Balance Masters. The Tag tires are the newest on the coach DOT 2018 so I will keep those for now but plan to replace them next year. Most likely I will move the steers to the tag and put the newest tires on the steer.

Good plan

Ben,

That placard is only a guide as tire brands and models can be significantly different. Plus, the placard is for a FULLY loaded coach at the GVW rating.

The Dynasty we are picking up has two different size tires, one size on the front (which is the correct size for the coach) and a different size on the rears which are all a fraction smaller but will work if inflated properly.

This coach will NOT be fully loaded as all of our normal stuff that we carry in the coach will be back home in Florida. It is basically empty.

Based on everyone's feedback including yours I feel comfortable with the Cold psi's I have chosen, 110 F - 95 D - 85 T.

115 psi on a Goodyear 295 80 22.5 16ply would support over 14500, inflation should be based on actual weight, placards show max weight inflation pressures, if you don’t need 115 psi don’t inflate that high, it will cause an unnecessarily  harsh ride 

16 minutes ago, Ivylog said:

And you can feel that difference on the rear of the MH? I’m running 315s on the front where I can feel the difference over a 295 at 10+ psi.

OH, never mind.., you win!

Don’t know what you are driving but I know I can feel the difference between 115 and 105 on my front axle which is supported by 4 bags just as the drive axle is, I would expect that harsher ride is amplified with 4 tires being inflated to higher psi over two, but that’s just a guess, that along with the significantly higher bag pressures make me want to do what I can to soften the ride in the rear, for the coaches sake and for any ride improvements I can gain, the OP will I am confident make the right decision for their circumstances and their budget, if they can afford better RV designed tire I’m sure that’s what they will do. They can certainly buy commercial tires that will do the job adequately bearing in mind that commercial tires are designed for longevity not ride quality.

While Moxy’s psi happened to be close, they have little similarity to your 06 Dynasty. His 01, first year for a tag on a Dynasty with only 275/80/22.5 tires plus it weighs a fair amount less than a 06 Dynasty with 4 slides.

Do a EBay search for Hankook (or any other brand) 295/80/22.5 tires and then Hankook 11R22.5. Yes, the 11R is less expensive than a 295 but good luck finding a 295 on the road when you need one.

The only reason to run 295s on the rear is because they are the same size as the front but not necessarily for the amount of weight on the rear axles, unlike the front. I wonder how many miles the previous owner successfully put on the 11Rs on the back of the rig?

As posted, you should be able to get $100+ for the takeoffs, especially the 11Rs, probably the most common truck tire. There’s a lot of nothing between SLC and Flagler Beach…good luck getting a tire installed, assuming it didn’t destroy anything important, in the middle of nowhere and at a reasonable price.  Good Luck as it looks like you’d already made up your mind before posting. The least I’d do is 2 new on the front as a Big Bang on the back is not near as exciting as one up front.

 

Agree, 295s and 275 at the same pressure support more weight than the 11r 14 ply but can be found with 16 ply which have lower weight capacity at any given psi than 295 and similar to 275  and if we agree that lower psi translates into softer ride, 295 80 22.5s are the way to go imho, or 275 80 22.5 which has 500lbs less capacity at same psi  still has better ride than an  11r 14 ply or 16 ply iirc,

Besides the point, but I always find it curious talking about the cold pressure. Your cold pressure in SLC is gonna be so much higher when you get south. I know mine is and so I change it with seasons.
