Start around 25 psi. and see how it grips. I know some people that run high psi (25+) and some that run low psi. (12-15 )

Move down to 20 the first time if you need to and then go down in 2 lbs. increments until it hooks. Do not go below 15 psi..

Since you are FWD do not forget to jack up the rear psi. to 40psi. for less rolling resistance.
