I have found two things. two much pressure will wear the tires very quickly We tried up to 44 and not only were they greasy they wore very quickly. My car is heavy (2750#) and like 38psi. The wear there is just fine.

I have also been able to cross rotate my tires. Once they have a couple good heat cycles in them the wrap shouldn't matter. I was always nervous to do this but had an engineer from Bridgestone tell me it is fine once heat cycled in. He told me all tires are wrap in a direction and that is where the direction arrows come from. He did go on to say if there was too much grip via aero or even mechanical it could change his statement. I don't think most of our cars will fall into that category...
