If your stagger isn’t right, due what post 3 and 4 say to do, but if you have your stagger right, just roll with 4 psi...jmo...
That's good, just remember when you get home after the races and after you clean kart and tires, let all the air out on left side and keep 10 psi in the right, that will help you on maintaining your stagger, that's what we did and it worked for usYes I checked stagger right before I put internal in
