Air Pressure

[#1footballfan]

We have a 2019 DS. I was wondering what you guys thought was a good tire pressure setting for your coach? Currently my are about 103-105lbs.
I wanted to make sure we have them correct so we get the best wear out of our Michelin tires.

The only way to know is to get your 4 corner weights. But as long as you don't see any abnormal wear, your tires will age out way before they wear out.

No one else's coach is loaded the same as yours. You need to get your coach weighed so you can look it up on the tire charts for your tires. Ideally you would get weighed at all 6 wheel locations. If you can't get to a location for that, at least get an axle weight for all 3 axle's. If you do the latter, when you divide by 2, add 5-10% to account for side to side weight imbalance.

Steers or Rears? I run my steers at 115 and rears at 80 if hot, 85 if cold out

I am guessing you have Michelin 365/70-22.5 tires on the steers. they are rated at 10500# per tire at 125psi. Depending on your steer weight, you can lower the psi for a better ride. There is a chart out there in the internet world, but it is Easter. It appears to be hidden for now.

Found it.

Download the truck tire book and go to page 73 or there abouts. Get a single axle weight if that is easiest. I have read that if that is all you can get, as opposed to individual wheel weights, take 53% of the axle weight and use that for individual weights.

I just saw your post. I thought the 43 footers used the 365 tire. The information is in there for that as well.

Gotcha Bradfield. Football fan has the 43 footer. I run 125psi on my steers, 90psi on my drives and tag.
