Tire pressure

[Wayne Thomas]

I have a 2002 Monaco Windsor PDK  what tire pressure is happy medium for a smoother ride

[DavidL]

You should have the RV weighed for each axle, compare that weight to the tire specific chart which will provide you the proper pressure.

It doesn't make any difference what others use.  You need to use the pressure for your rig as you have it loaded.

The softness of the ride will "be what it is".  Don't overinflate, and definitely don't underinflate.

 

If the ride is not nice enough, consider upgrading to Koni shocks.

Some tires are softer than others, even when inflated correctly.

Other than that, enjoy the ride.

DOUBLE DITTO…. Fully loaded, Full tanks (fresh & fuel) and both pilot and copilot.  Simple two step process (in your manual), but here is the Readers Digest version.

Find a scale that has the weight pads flush or at the same level as the driveway or 3ntrance.  Find one like that, that does NOT have a curb or guard rails on each side. All truck stops have them…moving companies….quarries.  Must have two separate scale pads…3 is OK.

DRIVE on and get each axle (2) on a separate pad.  Blow your horn or signal. WEIGH ME.  THEN, pull ahead and come around again….this time, leave on side’s wheels on the scale and the other side on the surface beside it…same drill…split the Axles….  Give them the WEIGH ME signal.

Look at the scale sheets.  Mark the “one side” only as DRIVER or PASSENGER….  THEN, Subtract the “one side” front & rear from ENTIRE MH respective front and rear.  Bingo….all four corners.  

OK…first RULE.  Use the MAX weight for each a axle (front and rear) and set your pressures, from your Tire Brand’s (google them) Inflation chart.  NOW….if there is a big Side - Side difference, see if you can revise how you have stuff stored in the bays.  Some folks carry a tool box big enough to repair a NASCAR race car at the track.  Then, guestimate a little and you can probably drop the pressures down on that axle.

BUT…if you exceed the weight limit for the total axle….move stuff to the other end or put in the Toad or get rid of it.

You can also, and we Moderators always suggest this, first before you post.  Use the search box in the upper right.  I used “Tire”.  But, then you click on EVERYWHERE and chose TOPICS.  There was one that went into a lot of detail about understanding inflations charts and TP.  Here it is.  Read it.  Very informative as we had some folks that were having trouble understanding an “illogical” TP…so, it got explained.

Okay not a great picture but there is the tire placard from 33,000 lb GVW 2005 Holiday Rambler ambassador for comparison

WEIGH YOUR COACH. Four , or Six corner weight is the best, but single axle weights will be OK too. Fuel and water full. Black and grey tanks empty with your stuff on board. CAT scales at many truck stops. Tell the clerk you want to weigh a coach. There is an intercom at the scale so you can communicate with the clerk. There will be 3 platforms for3 axles. Steer axle on the  first, Drive on the second, and if applicable, Tag on the third. Keep the ENGINE Running, so you stay at Ride Height.Get the print out from the clerk. IF you have a tag axle, you may have to adjust your DOWN pressure to move weight as needed, and after adjusting your down pressure on the tag, REWEIGH the coach.  Now go to YOUR tire Mfg. inflation charts for the correct COLD inflation.

I'm a brand new 2005 Monaco owner - where does one find this placard in the Coach?

Usually on the vertical sidewall of the console to the drivers left.  Otherwise, in a closet.  BUT….JUST AS EASY…Download the sales brochure.  That will tell you the size tire’s it supposed to have and the Axle capacity.  Thus, you don’t need the plate.  Look up, on a Goodyear or Bridgestone inflation chart, the pressure that match the capacity of the axles.  That is all Monaco did.  

Then follow the instructions for weighing and look up your brand and size tires, fully loaded based on the corner weights.  That is what you should run.  All the placards told you was what was used to achieve or use the full @xle capacity.  Then, weigh and determine what the real or actual pressures you need for the weights.
