How much air pressure for 17"x2.5 front tires.Running 35psi, is that to much? 400 lbs on front end.

My JrFuel FED we weigh around 325 across the front axle, and I run 40 psi, That should work fine, unless you have a good size front wing creating more down force. More down force = more tire pressure. Big Show Top Fuel run 80-10 psi.

Just keep the same amount of stuff on the right
as there is on the left. Seeing straight ahead is highly overrated....
