Max recommended/allowed difference between min & max tread depth on quattro = ?
 

I recently ruined one tire (DOOOHHH!!!) hitting a rock on a "spirited" drive. I bought a replacement (same tire/size as b4) but was told by one tire dealer that biggest allowable difference between tread depths is 4/32". As such they would not do install - liability, blah, blah ,blah.

That meant I needed to buy a second new front tire for another $150. Went to another tire dealer (they have Roadforce balancer) who then told me 2/32" max difference. WHoaaa - this would have required two MORE new tires or PITA tire shaves. Current tires only had 6k miles on them and although rears prolly only had 4-5/32" on outer edges, but middle and inside was 6-7/32".

Went back to first installer and they did the front two tires. I know have 10/32" on new fronts and between 3-6/32" difference depending on where you measure between front/rear.

I have compensated somewhat my overinflating rear (45 psi) and underinflating front (36 psi) - no lectures please about how this upsets handling characteristics.

I know this is an important issue with quattro, but is there an actual AUDI quantitative requirement as opposed to "all tires shall be same diameter" type statement.

you might want to ask over in the tire forum,....there's a few people from tire rack there

Thanks, I should have thought of that...

np....i go there every now and then....only when i want to talk about....<yawn> tires....8^)
 

have a great weekend
