Question Motorhome Tire Pressure

Hello - I'm the new owner of a 1997 Holiday Rambler Class A 32 foot motorhome. It's built on a Ford Chassis with 460 cid gas engine - no slides and has only 12,000 original miles. All of the tires have recently been replaced with TOYO tires just prior to my purchasing it. Does anyone have the correct cold tire pressure that I should be maintaining for all six tires? Thanks in advance for your assistance. Glad to have found this website as I'm sure I'll have more questions answered as a "newby" to the RV world..

TOYO website should have the info to download after you weigh the rig to get the real weights. You'll also need the correct model and size of the tire.

I just weighed our front today, 18,030#'s and according to the Michelin chart that takes 105 psi.

That's what you need to do to get it correct but till then look at the side of the tire, it will have a minimum pressure to carry the maximum rating of the tire. It'll probably be too much but that's far better than too little pressure.

Weigh your rig preferably on all four corners with it fully loaded, water, fuel, proane and all of your stuff. Don't forget about passengers. Do your best to equa!ize your weight and weigh again
Email Toyo for their pressure chart.
Pretty amazing for us. Our fronts needed dropped alot and rears were to low.

In the meantime there is usually a sticker on the wall behind the driver giving recommended tire pressures for each axle, as well as vehicle axle weight. That should get you in the ballpark until you get your rig weighed.
