Thanks everyone for the inputs. After I got them put on yesterday, the installer had them set at 37-38 PSI and I reduced them to 32 after I got home. I did a little spirited driving on the streets (I know, not the brightest thing to do) but after a couple hard turns I noticed the scuffing was just starting to reach the little arrow markers on the front. Now that I think of it I wasn't smart enough to check the rears, but can do that next time I head out somewhere.
A few other notes. These tires are LOUD compared to the factory Eagle F1 Supercar 3Rs. Not that I mind, I don't, but just noticed it.
These tire have way more starting/cold grip than the 3R's. Before, when entering most onramps, 1/2 throttle would spin up the rears, but not with the 71R's.
Looking forward to a good auto-x season this year.
