Consolidating some thoughts from other posts on V70 XC Tire Wear:

I, and others on the forum, have noted significant outer shoulder front tire wear on V70 XCs (mine is a 99 model). This negative effect is impossible to mitigate through straight rotation (although at least your front and rear tires will have the same worn outer shoulders). If you go to the trouble to rotate your tires *between opposing wheels* you can spread the wear across the inner and outer shoulders. That is, you have to have your tires unmounted from your wheels and switched to opposing sides so the outer shoulders become the inner shoulders. This is not the typical rotation pattern.

One forum member (Steven) took the trouble to experiment with his alignment and adjusted the front camber to a full negative 1 degree. That has appeared to correct the wear problem.

However, is there anyone on the forum that can comment on the effect that change might have on other suspension components or on handling. Traditionally, negative camber improves lateral grip at, perhaps, some cost in initial turn-in response. Does that hold true for the XC AWD setup? Will going to negative camber have any detrimental effects on the vehicle?

I spoke with my dealer and they describe the excessive wear as normal. However, since it means that I have to replace all four tires when the outer shoulders are worn down while the rest of the tire is fine that seems to me to be an unnecessary expense if there are other changes that will correct the wear.
