One Flat Turns to Four

[Stephen Kormilo]

Grant,

The difference in circumference between a new 16" tire for my A4 & one 
with 3/32" of treadwear is less than 0.75%. Not enough to make any sort 
of difference in diff. wear for real world driving where steering 
corrections left & right are a 'fact of life'. There may be some extra 
strain on the diff. in a 'lab' type situation where the car is driving 
in a perfectly straight line for thousands of miles, but given slight 
differences in tire pressures & the manufacturing tolerances of the 
tires & drivetrain, I doubt it.
