tires

I need to buy six 11rX22.5 tires. I have no idea what I should be looking for. Whether to buy them locally or is there a good place to have them shipped from and change them myself. What spec's should I look for? Different tires on rear than front?

Shop around. I've found good prices locally and sometimes truckstops will have tires on sale. I'd expect *Good* name brand tires at around $300-400 each. I run typical steer tires on the front, open shoulder drive tires on the back (on a tandem axle that does a lot of parking lot and city street turning, the shoulders will wear faster so for a use like that I'll switch to a closed shoulder design).


Most tire shops will insist on valve stem replacement with new tires. Balancing is sorta up to you, I rarely do on big vehicles, others swear by it.

I just bought new steer tires, Michelins 1100x22.5 at Petro Truck Stop and it ran about $1300 if you want the best, otherwise pick your favorite brand, HO-CHI-MINS are ok for rear but I want good tires on front, if you ask they will put beads in them so they are balanced for life of tires. sportyrick

another brand not to forget is Uniroyal if you are looking for name brand, they are a division of Michelin and i got mine 3 years ago for much less than michelins.. so far so good.. that bus ive only run about 20k on but the tires have been great.. I rarely ever have to add air to any of them.

A few additional things may prove useful.

You may find more options if you switch from the 11R to a more commonly available size. You'll have to confirm but I think you might would be looking at 275/80R22.5.

The front tires must always be "steer tires." The back tires can be steer or drive.

If doing all highway driving, get OTR (over the road) tires. If planning to do a lot of mudding, consider "terrain" tires (make more noise on the highway).

You will find plenty of debate online about 'expensive' vs. 'cheap' tires, balancing vs beads, and most everything in between.

If you've got the tools and know how to change these massive tires, go for it yourself. If you've never done it.... well... it will be a learning experience!!

Thank you guys, all this info helps. Even just hearing the terminology helps. I had never heard of the beads.

I dunno, the 11R22.5 is a *VERY* common tire size on big trucks. Not sure how much more common you can get.


On the front you can either use steer tires or "all position" tires. Using "drive" tires on the front, while legal, is not recommended (I would only do this on an urgent, temporary basis) and *NEVER* put a recap/retread on the steer axle.

11R22.5 are fairly common on school buses as well. That is what I am running on my Bluebird.

275/80R22.5 are what I run on my pickup.

I am with Brad NEVER put recaps on your steer. I run recaps on my drives and have had good luck with them.

Yea, I want no part of caps. I figure the cost of one roadside service to replace one would pay for the difference between caps and new, not to mention the inconvenience and even danger.
I actually wired up a Bandag plant in Yreka Ca in my youth. They told me they had some secret proprietary system that resulted in superior caps.
