OK you tire GUYS

Need help w/tires, on rear axle, duals tires- can you have on the inside (size) 255/80R 22.5 XRV & on the outside 255/80R 22.5 XZE ? I do have the XZE on the front & they are better than the old XRV ones on my pusher.

An expert on tires I am not but I would think you should keep the same tire on both inside and outside of the rear duals.I'm not saying you can not use the 2 different tires but it would be safer not to. I do not know without some research what the XRV verses the XZE means but I'm sure someone will be able to answer that. . The DOT being referred to is most likely the Dept of transportation rating stenciled on the sidewall of the tire....Alan

The dot is print in the side of your tire,( big numbers,) and it will indicate the month, and year, of the fabrication

Allow me to make one minor correction. The date code represents the week and the year the tire was manufactured.

For example: a date code of 2809 would mean the tire was manufactured in the 28th week of 2009.

As long as the tires are the same size, they can run side by side without trouble. Be sure to maintain recommended air pressures.

Ok, here's what Michelin says about the XZE.
"A premium all-position radial with extra-wide, extra-deep tread designed to help deliver our best wear in high scrub applications."

And here's their top line on the XRV.
"The all-position radial designed specifically for exceptional performance on recreational vehicles and motor homes."

I would construe the XZE to be a tire designed for a tag rear axle that scrubs the road a lot. Still, the two can safely run side by side as long as they are the same size.

If it were me I'd ask the Michelin folks where you get your tires.

While they are the same trade size, that does not mean they are the same size. What you need to do it look up the actual diameter (loaded) at your running PSI. These need to be the same. If one is slightly smaller than the other then the revolutions per mile will be different and this in turn will cause one tire to 'drag' the other, causing increased heat and wear.

However, even if all the tires were originally the same size, since they are used I doubt they will still now be.

I did not see in the OP if both tires were new. Even if they are both new, with the different tread design they could be different in size. Measure the tread depth and if there is more them 3/32 difference I would not recommend putting them togather on the same position.
What happens is that the larger tires will carry more of the load and 'could' be over worked. Anytime we work on vehicle with dual rear wheel, we want all tires on that axle to be the same.
I am sure that there will be other thoughts on this but for me I would not mix them on the rear axle

Very slight difference when new.. XRV is 38.4 in diameter 541 revs /mile the XZE is 38.5 inch and 538 revs/mile. But if the XRV's are worn, the difference becomes greater. Different rotation but also larger dia. tire carries more of the load...
But if the XRV's are paired on driver side and XZE are paired curbside, the tires would turn and share the load the same as their mate.

This came up when I had tires rotated, they moved both fronts to the driver side rear, and those tires went to the front. "keeps them paired for wear". Next rotation would be Right rears to the front...

Marlybelle,

We do have a tire expert on this forum. Give him a shout.

TIREMAN9

and go to his blog and ask questions there, or read what he has to say about tires.

That difference is so minimal, it's irrelevant. Just MHO.
