rims-for out of round and lateral run out??
do the japanese have tighter (better) specs? giving smoother ride?
never seen that discussed
Each car has its own specifications. If you have access to Alldata, you can find the spec for just about any car made in the last 25 years. Enter several car models, and note the specs you get.
I remember the last time I had to use specs, it was for a Honda Civic. What I didn't see coming was that the tolerance for steel wheels is wider than the tolerance for aluminum wheels.
