Help !! Tire pressure?? Just got 245/40/18 perelli p zeros

The place where I bought them set the tire pressure at 44psi. Is that too high??

44psi is ridiculously high.

My 235/35/19s are currently running on 40psi all around.

I ran my 235/40/18s setup at 38psi all around.

44 sounds like max psi

try somewhere between 34 and 36... some people will have opinions on this. The higher the psi, the harsher the ride, but more responsive the cornering (i think). just be sure not to underinflate them, cuz thats really bad for traction.

Second..44psi is max inflation (ok for autocross), but stick with ~36-40psi
