There are Steer, Drive and trailer tires.  All have different loads on the tire.  I have steers on all six positions.  I am moving the front tires to the rear and getting new front tires every three years.  Six years on each tire.

Usually the words steer, traction and all-position indicate where they mount.

While our 295/75-22.5 don't touch the bags in parking lot turns, they will keep the bag ends polished as they do touch in quite a few situations. Don't think this would be a factor with the Continental plastic end bags either as it's not a big deal. Our 295s are about 3/4" of an inch wider than the 275 Michelins. May be different brand to brand.

We mount all position or steer tires for all six locations. Traction tires may introduce some noise into the coach. We don't move the coach without a spare tire onboard so it would be more difficult if we had two different types of tread patterns. Keeping fingers crossed but we have never had a traction problem even heading down from the highway to the ocean in sandy/dirt river beds in Baja or forest service roads here in the states.

It's my understanding that tires with angled sipes (cuts across tread) are directional and must be mounted so they turn in the direction of the arrow.
If the sipes are not angled or tires are not siped, they can be mounted to rotate in either direction.

Another good reason for choosing a spare that can mount anywhere!

Quite proper to put "steer tires" on all axles of a Class A motorhome.  The exception would be for the rare owner who does un-paved roads, deep snow, etc where they would get a more aggressive tread for the drive axle.

Good point, up north I always ran a "aggressive" tread, knowing "harms way" was my world. As much as I love the tread we have, I'd be freaked out driving in the "nasty". I have never had a tire outlet ask, "where are you going to be driving?"

Has anyone tried Crossfire pressure equalizers?

Yes I use them. I used them on my class A truck when I was driving over the road so putting them on the coach was just natural. Advantage for me is is easier to air up the tires and I only need one tire pressure monitor sensor for each dually. May not be for everyone but I like them.

Jerry, I though that the word "steer" stampted on the Michelin tire was to indicate the direction in which the tire should roll,when mounted, not the position on the vehicle that it should be mounted. Am I wrong?
I do not know the answer to your statement.  I thought that steer meant that it was a tire for the wheels that do the steering.  That may be incorrect.  From personal experience though I can say that these tires do not have much traction on slippery surfaces like wet grass and muddy places.  I will not purchase new tires that do not have cross grooves in the thread.  I see tires with this type of thread on the front wheels of truck/tractors, but have not seen them on the drive wheels.  The type of thread I am talking about has grooves in the direction of travel, but only some sipes  across the tire.  I don't normally drive on dirt roads, but there is the possibility that I could encounter a slippery spot.

Maybe things have changed, but the info for our Michelin XRV 255/80R 22.5 tires, say,
 "The all-wheel position/all-steel radial tire designed specifically to provide exceptional performance for recreational vehicles." I sure like them, down here!  ^.^d

Agressive treads are better left for the things we tow behind our FT's.  17-20K pounds sitting on dual "steer" tires will dig down farther into dirt, mud or snow than we can recover from without help from Jamie Davis and his rotator.  Personally, I'll take the quiet ride from 6 steer tires and leave the fun stuff for the Jeep and ATV.

I have steer on all corners and even thru the ugly travel down thru Washington and N California this Jan with the snow and ice I had no problem driving the highway even with many "chain up " signs and stops we went thru. My only problem was trying to get up a steady climb into a Truck stop with jack knifed trucks etc all over the place. Second try made it up.
That trip was an oddity with weather for sure. Never again leaving it that late to get away.

Based on what's on my car, directional tires from Michelin are usually molded with "Rotation" and an arrow to show relative mounting.  If a steer tire is directional as well it should be labeled that way.

Correct.  No arrow, not a directionally sensitive tire.  Said another way, without arrows indicating direction of rotation, the tires can be mounted and rotated through in any direction.

Has anyone increased the size of the tires they are using to 285 or 295??
John
295/75 and 275/80 have a slightly different aspect ratio (relationship of the height to the width) with the 295/75s being less than one inch wider. Their diameters are very close to the same and only vary by the manufacturer. They both turn about the same number of revolutions per mile so no real difference. They have no problem clearing each other in the rear. A 285/75 would be smaller (diameter is less) than the 275/80-22.5 Michelin and turn more revolutions per mile. So, going to a 295/75 is not increasing the size, just a tiny bit on the width.

I was not as clear in my original post as I should have been . The Michelins on my coach did have the word "steer" and there was a curved arrow as well. This is what led me to believe that the direction of rotation was indicated, particularly as the arrow was pointing in that direction on all 6 visible sidewalls. Remember that the DOTdate is only visible on the outer wall of the tire.
