Does anyone have experience with these tires? I picked up a set in 225/50/15 for lapping/solosprint and any help with starting tire pressures to try out would be appreciated. I'm used to running a 3600lb car on Victoracers so this is a huge change for me. Thanks.

 

Here's a starting guideline i got from the Audi club list:



>In the event that you aren't able to find a recommendation for your car, or the tires on your car are so different from those that were originally fitted from the
>manufacturer as to be incomparable, we received the following rule of thumb from Oscar Pereda, an engineer for BFGoodrich. He calls it a "realistic starting
> point," saying it has never been just right, but is a good place to start. The rule is:
>
>(Vehicle Weight in lb/100) + 2 psi at heavier end + (2 psi all around if suspension and alignment are stock).
>
>Example: Stock 911, 3,000 lb.
>(3000/100) = 30 psi
>Add 2 psi all around = 32 psi
>Add 2 psi to heavy end = 34 psi at rear
>With modified suspension, the result is 30 psi front, 32 psi rear.
