We use This brand at the truck company I work for. They are great tires. Alot tougher than Michelin.

His Michelin XZA3 tires are load range H. The only way up is to increase the size.

I have a 2007 Bus QSP with Spartan Chassis. The previous owner, for the same reason you are considering, changed the tires when the coach was only two years old to Michelin 295 80 22.5. Having only 95 to 100 PSI tire pressure in front makes the coach ride nicely. Good luck!

By doing that did the previous owner switch out the 7.5 inch rims to 8.25's? Are there any clearance issues?

I couldn’t tell whether the previous owner replaced the rims or not. It has aluminum wheels; if they did it was really expensive. Where you buy the tires should be able to tell you if you need new rims. Also, did you call Tiffin to see what they recommend?
All the best!

I'm curious about determining axle loading so I'm going to ask what may be a "dumb" question.

In this thread where front axle weight ratings are discussed in terms of a few hundred pounds (on a 14,000 lb plus axle) I have to ask; is gross front end weight used to determine being above or below axle limit? If so, would it be reasonable to subtract 2x(tire + wheel + rotor + caliper) weight to figure axle loading?

Thanks for any insight.

Although, I must admit, I'm not an expert on weight determination of the front axle, but it appears to me that it should include the weights of the tire, rotor, etc, as the tire, in this case, is carrying everything. Perhaps someone else can chime in if I'm mistaken.
