I rotate my vehicals tires every oil change. With my previous vehical (a pickup) the front tires wore down much more quickly than the rears. The difference in wear was really noticable.
My guess is because 70% of the braking was done by the front wheels. So I really did increase over-all tire life by moving the rear tires to the front.
(picture of L.A. driving pattern: Accellerate like mad to 45mph, travel 1 minute, Slam on brakes. Repeat 50 to 100 times a day.)
Today I rotated the tires (wheels really) for the first time, this being the first oil change. I did not notice any difference in wear between the front and rear tires. But I did notice something else.....
The front wheels were quite pitted on the inside of the rim in the front wheels, but not the rear wheels. Since I am sort of a nut about keeping my cars clean and new looking, I polished down the corrosion on the wheels and waxed the inside (Billy suggested I do this about 5 months ago, boy I wish I had taken his advice sooner!).
I guess the brake dust from the front pads gets wet and creates a caustic or acidic fluid which then eats into the unprotected aluminum rims. The back wheels, being protected by the wheel skirts, don't get wet very often (at least where I live).
Anyway for those of you who do not rotate your tires often... for you it's easy, for your rims...it's the pits... :lol:
