short question. Is it critical in 4Matic models to maintain tires and
the same level of thread usage. I know it is very important in case of
Subaru's and their implementation of AWD where the system reacts even
for very small differences in rotation of wheels. 4Matic is very
different as the computer applies brakes in case of wheel spin and all
diffs are open.
In my '00 E320 4Matic I got two tires in very good shape and two to be
replaced soon. Normally I would replace set of four. Thus my question.
