My son has them on his vette. Great tires! I would suggest start at 18 and go down from there depending on your launch rpm etc. to see what works best for you.

20 psi worked good for me on my 555r

The proper psi is going to be relative to your power output. Start @ 20psi as mentioned above.

Mine did not like under 17 pounds. They do like lots of heat in the burnout box.
