I believe 25 psi is max for raceline, but you may want to call Raceline to confirm and find out why. There is probably a good reason.I'm getting a set of 17" Raceline monsters beadlocks and putting 37" Nittos on them! But the shop said that the instructions said max PSI was 25. Does that sound right? What is the max PSI you can run on beadlocks? What's recommended?
