It's time for new tires all the way around after the 1st of the year. I've been running Bridgestones on the drives and got 152k on them so far. The steers are Firestone's with 70k on them. The Bridgestones I've been real happy with and most likely will put the same back on. The Firestone's I've had to rebalance 3 times and you can still feel a slight twitch around 70mph. since the last balance job. I'd like to hear what kind of luck others have had with their tires before i drop the bucks on new skins.

I run Michelin XZA 3's on the steers. Had them for over a year, and there's hardly any wear on them so far. No irregular wear patterns, either.

My drives are Michelin X-One's. They ride much better, and fuel economy improved slightly with them. They did wear a little funny on the edges, though. That, and the rear drives had a lot more wear than the fronts. I rotated them and changed my shocks, so I'm hoping that helped.

I know the "super singles" aren't for everyone. They will incur a larger start up cost than just switching over to new duals. IMO, The fuel savings alone helps to pay for that in the two years I expect to get out of them.

If I didn't have the X-Ones, I would probably run the new Michelin XDA 5's on duals. They are guaranteeing that you get 30% more life from them than your last tire, or they will give a credit twice the difference in the purchase price between our old tire and the XDA 5. To me, that's worth it.

If you go to the Michelin truck web site, you can 'test' all tires for rolling resistence (a big factor in fuel milage). Here is the [LINK POSTED BY MEMBER] Only Members Can View This Truck Forum Link. My research indicates that the XZA3 for the steers and the XDA3 for the drives are the best buy for my needs. Rolling resistence figures are: 101 and 115 respectively. I presently have Goodyear G395 and G372 with rolling resistence being 123 and 139 respectively.
Hope this helps.

Thanks, interesting link. I have never rotated my drives and they all seem to wear even. What kind of miles should a guy expect out of steers and drives? This is my first truck and the first set I've wore out. Can i really expect better mpg even with a w900?

All depends on what you are hauling, I haul really heavy and expect to get 90k on Michelin XZA-1 steers and about 225k on bridgestone 726 el drives

We have X-1's on tractors and trailers and we are very dissapointed. IMO they wear out fast and have bad sidewalls. Bridgestone's are nice and so are Goodyear's

Pull a van, mostly longer hauls, nothing over 44k. Here i was thinking 152k was decent miles for the rears, but 225k kinda blows that outa the water. I haven't asked anyone yet, but I'm assuming they are due to be replaced once there are getting close to the nubs in the middle of the tread. they are all about a 1/4 inch from the nubs.

Our trucks come with Continentals new, I think they are numbered 610's, though I would have to check on that when I go outside. My truck is still on the original tires, has about 219k on the odometer. I expect that before next winter rolls around, they will require replacement, so I expect that they will go to about the 300-310 mile mark. They'll still be good carcasses and suitable for recapping at that point.

I've had the steers replaced twice, but the truck was in a front end involved wreck before I got it, and it ate up a recent set of steers in about 110k miles. I had it aligned recently, and am hoping that the current set will last longer. I believe the fronts are Michelins right now, but I'd have to look for the model numbers there as well.

I typically pull 48-50k in the trailer running around the midwest.

Bad sidewalls? Hmmm... Mine are just fine. I did have a wear problem on my rear drives, so I rotated them to the front. Not sure why that would occur. I replaced the shocks, thinking that might be part of it. I'm not noticing any similar wear (yet) out of the rotated tires.

Bridgestone M726's are topps.
