I have just noticed a significant wear to just the outside of both front tires on my MH, it's just the outside edge about halfway to the first groove, it's kind of wavy. Its a W-22 with G 670 19.5 with 15k on the MH. I have weighed the coach and using the formula I have, gave me the 80PSI all around which was in spec's for my weights and tire cap's. I have added a reflex steering stabilizer about 1 1/2 months ago (we have traveled with it installed for a while). Installed Pressure Pro system before this last trip (these do not require a rebalancing), and changed my tire pressure on all my tires to 85psi to increase gas mileage. And now this happens, what have I done wrong? We just came back from Blairsville, Ga a lot of curvy roads and hills. The highways had a bit of construction so we hit some rough roads, nothing hard enough to ruin an alignment. The coach runs fine handles good and does not pull, wander or have any vibration. Any ideas? If you think an alignment is the answer any recommendation in the Jacksonville, Fl area?

Had similar wear on mine and found the toe in to be incorrect. This was 15000 miles back. Swapped the worn tires with the drivers side rear duals. No new odd wear since then. Toe in was out by 1/2 inch. Check toe in.

Had the same tire wear on our Bounder with a W22 chassis. Took it to the loacal allignment store and was told that the outer tread was separating from the inner tire base. This was most likely caused by rough roads and hitting pot holes. The tread show wear because as centrifical forces act on the damaged tire the outer tread makes more contact with the road and wears faster than the undamged portion of the tire. Believe it or not.<pre class="ip-ubbcode-code-pre"> </pre>

The signs that your are describing point to a a condition that can be resolved by setting the toe parameter back to factory specs. It has been noted here and I have also experienced that the toe can be out by as much as a 1/2" or more. This will cause severe abnormal wear of the shoulders of the thread.

This condition is best resolved by a good front end alignment and rotating the tires with a pair off of the rear axle that have square shoulders.

Update, took the coach to Horton Alignment on Beaver St here in Jacksonville, Fl. Very good job, tech knew the spec for the W-22, about my Reflex steering stablizer and how to move the Pressure Pro sensors around, I was out 0.25. Rides with one hand, also I have just installed a Rear Trac-Bar from Henderson. So we are riding fine!!

The very first thing is to assure that you have a good front end alignment and properly inflated tires. You would be amazed as to how many problems simply disappear.

The rear track bar is a welcome addition on some coaches and is now a component of the Workhorse SSC option.

You are right DriVer, making sure all of the basic items are working correctly before you add any upgrades will make it easier to troubleshoot any new issues. The alignment was knocked out on our last trip, on the way back home. I had not installed the rear trac bar yet and the front stabilier had been installed for at least 800 miles or more with no tire wear. I watch the tires very close. That how I caught it so quick. It now rides very good.
