tire rotation

I rotated the front 2 tires to the drivers side rear because my front tires would vibrate at 45 mph..
So since 2005 once.

I had the rear duals (22.5 inch rims) off a while back for maintenance. Just fighting with those two and torqueing 10 lug nuts to 600ft-lbs was enough fun for me. I am not going to rotate without a real good reason. Now if I had 19.5" or smaller I would consider it a lot more.

My tires are the same size. they have direction of rotation, not rotating tires, on the steers. If you have six or eight aluminum you could rotate them.
I was taken aback when I saw that they did/do put all the wheels in aluminum.

If you do rotate the tires be sure to incorporate the spare into the mix; if you have one.
My guess is that rotating tires on a MH is a VERY BIG JOB and virtually no one does it.

not me.

I thought I'd rotate my brand new spare tire in. That's one reason to do it. The previous owner bought 7 tires.

Many RVs have different size tires front and rear, so one would be restricted from rotating.

On the other had, I rotate my tires because I have front wheel drive. My fronts wear much faster than the rears, so when they are about half worn, they get moved to the rear and a new set gets put on the front. The rears on mine take for ever to wear, so they get cycled through. I end up buy two tires every third year. This way I can get reasonable traction in the snow.

I doubt I ever will rotate my tires as I have no idea that I will wear out the tread before the tires get too old to be safe anymore.

No reason why you can't. I won't unless I start getting an strange wear pattern on the front and would have the service tech rotate the tires as part of a front end check out or alignment.

I am not aware of any tire manufacturer who recommends rotating tires on a Class A UNLESS there is uneven tire wear.

Tire wear is much less an issue then on a car. You will very likely replace tires due to age, not tread wear.
