Tire pressure for 275/80R22.5 LR H tires
I'm sure this has been a topic many times in the Class A forum. I have been searching for quite some time but can't find a recommendation, even in the manual. Running 6-275/80R22.5 load range H tires ...

"mikestock".....Weighing all four corners of your coach can be a difficult thing to do. It's hard to find someone who can do this. Better than nothing, is to way the front and rear separately. Most truck stops will do that for you, many even for free. I think the most I've ever paid is $7.00.
For right now, 110 psi sounds good until you get it weighed. I weighed my coach a year ago when I bought it new and after it was loaded. The weight charts said I could run about 105 - 110 psi. I was looking for a quality ride, so I started at the 105 setting. It was too low, over the last year, I've bumped them to 112 through trial and error. Last month, I converted to all electric and removed my propane tank (350 pounds) from just behind the driver's wheel. I checked my tires and at 12K miles, my left front was showing some under inflation wear compared to my right front. I attributed this to the propane tank and full wall slide on the driver's side. It would have been nice to have an individual wheel weight, but I haven't found anyone locally to do it. So with the removal of the tank, I adjusted the air to 115 psi and will see how that works. I know it will make my ride a little harsher, but I expect that my air pressure is dialed in for what is right for the coach.
The moral of this long winded post is that there are several factors when it comes to the front tires that you need to watch and may spend some time adjusting before you get it right. The minimum though, is to get that front end weighed.
