I have a set of Grooved Marshalls from Nac's that I remounted last night because I am going to race this weekend. I usually run about normal air pressure in these(about 8 or so) depending on terrain.... But my buddy tells me last night that he hear dyou are supposed to run the psi the mfg says or you'll pancake the rim.

Now I ran these all last summer with no problems at a low pressure...

What are all you guys running in yours?

 

18-20 they require much higher pressure than normal tires

 

10-4...I was running them at "normal" pressures for a with no problems... I have red Label Douglas's that I run them on with minimal bends(well at least not from bottoming out) But my buddy thinks I should run the 32psi they recomend on the side which I think way too much. I was going to try around 18 psi this weekend.

Thanks!
