Hi Tom,

Those are the correct pressures for most 26 coaches, both GM finished and transmode finished coaches. The only way to know for sure about your particular coach is to have it weighted wheel by wheel. Then look at the tire manufacturers weight to pressure chart to determine the correct pressures for your specific coach. These pressures are a little high for most 23s that are lighter than the 26s in most cases.

When considering tire pressures, also make sure your coach is at proper ride height front and rear. Most are low in front which effects camber, caster and toe and which can cause premature tire wear. Look on the GMC page on my web site for details on how to measure and adjust ride height and also how to insure your front end is aligned properly.

Jeff Sirum recommended these tire pressures to me years ago. I've used them religiously and have never had a tire problem. ??
