Wish I could say the same. I now have about 600 miles on mine (local trips only so far). While the handling improved slightly with lower PSI's, they still don't handle as well as my old GY's did, even with their rivering issue.

I've noticed something else with the Yoko's....the sidewalls turn brown if I don't keep them constantly coated with 303. Thinking they just got dirty somehow before they were installed, I scrubbed the heck out of them. Made no difference. As soon as the tires get wet and/or the 303 wears off, they turn dirt brown again. Cosmetic only I'm sure, but frustrating all the same.

If my handling doesn't improve by the first of next year I'm going to bite the bullet and yank them off and install Michelin's. Hope it doesn't come to that...

Thanks.

Check your inflation against the plaque placed on the coach by the manufacturer. NOT against the tire manufacturers "chart".

The tire manufacturer has no way of knowing what vehicle the tire will be placed on.

I was shocked when I compared the ride and handling back to back with 85 in front and 80 in the back cold pressure the coach manufacturer called for vs 100 all the way around per the rating of tire.

Gone was the wandering weaving and hard edge feeling of the bumps and ridges and my coach rode like an escalade compared to a bicycle on the rims.

Interestingly I didnt notice any change in economy either.

Why not try out what the guys that built your rig think-? ( I think you'll be happy.)

Most Tire manufacturers recommend weighing the coach filling the tires based on that. Ideally each corner and then following their chart.

Yup, that's what I did. The MH came from the factory with GY's. Different brand tires often call for different tire pressures, so the coach's factory tire label will not apply to every brand of tire.
