So I've got somewhere between 20K and 25K miles on my tires...

Since new, I've inflated them to 55/50 (F/R - 44psi rating).... I typically check tire wear at least monthly (except this month, I moved and haven't been paying attention).

So I just checked, and my driver's front tire has 1/32 extra wear on the outside (or you could say 1/32 less wear on the center).

AND my passenger rear has the same exact excess wear.... My tires are directional, I rotate Front/Rear (not side/side).

Any ideas as to why?, this is wear after two years of use at the above pressures. Would the explanation be different if it were just one tire? I'm not too concerned, there's plenty of rubber left and 1/32 isn't much... I'll just monitor more frequently to watch for any other change... If the difference gets up to 2/32, I'll deflate to "normal" pressure to see what happens (after eliminating the pressure variable).

Boo Hoo to you everyone that said I'd wear out my centers at these pressures
