What are your axel weights and what is the recommended tier pressure? What load range tiers are you running? Did it drive ok before?

Yep,
That's what I was going to ask too. Do make sure that your psi in the tires corresponds to the ACTUAL weight of the coach. And yes, I was also going to ask how well the coach handled BEFORE any tire changes. While it would be time consuming and, maybe a bit of a cost involved, it might be worth it to change all the new tires BACK to the originals, IF, the company still had them.

This of course, is just a suggestion.

Scott, kinda surprised that you want him to put his old and cracked tires back on. That's an accident waiting to happen. Or, did you mean purchased the exact same brand as the old tires?

Gerald, I've only changed tires once on our previous motorhome. There was no difference in ride or handling the day I drove off in the new tires. I did change to the exact same tire brand and size.

Hope that you can get it straightened out.

Good luck.

Well I got the rig weighed yesterday. After filling the water tank, and having a half tank of fuel,
the GVWR was 21,820 lbs.
Front axle was 7,340 lbs.
and rear was 14,480 lbs.

The manufacturer's specs were:
GVWR 24,850 lbs
Frnt 9,350 lbs @ 100 PSI
Rear 15,500 lbs @ 90 PSI

The tire specs were for the Michelin 235/80R 22.5
As everyone likely knows, that size is Michelin's own proprietary size. But like I posted earlier, the Toyo specs are VERY close.

Bill, I would glady have paid them to put the old tires back on just to check and see that my memory isn't out of wack concerning the ride. However, I'm sure they are long gone.

Some tires require a break in, usually 500-1000 miles. The heat cycles will help the nylon belted tire to stabilize.

I found this comment interesting if not encouraging.

Tonight I lowered the air pressure in the rear to 90 PSI and had my son both drive the unit and follow me to observe any irregularities. He saw none and left as bewildered as myself. Changing the air pressure may have had a slight benefit, but after nursing an ouchie for awhile, it becomes so hypersensitive, it begins to feel twice a large as it really is. So I guess my next step will be to have the alignment checked, but that will have to wait a bit. Another option I thought of was to take it to the Freightliner service place and get their opinion -- particularly concerning the actual chassis.

I want to thank all the responders for their suggestions and personal experiences. If I find anything of significance, I'll be sure to post it.
