proper air pressure

[ny300exrider]

what do you guys run for air pressure on your tires? i run 18in razr mx rears on beadlocks and 20in klaws up front on .190s and just got a new pressure guage so i was wondering where i should be on tire pressure for front and rear. if it matters i ride mx so i dont need them soft for sand or anything

thanks

For mx? Ive never raced, but anywhere from 5-7psi should be fine. I usually run about 4 or so. I like them soft.

I race mx and i have them about 8-10psi. dont want them too soft cause then they might bounce on you when you land, you know like bubble tires

5-6 for the back and 9-12 in the front depending on conditions. With beadlock rears you can run even less!

i run 3 1/2 in the back and 4 and a half in the front.

i always run right at 10 in my 19x6-10 front mx's, and i rotate from 5 to 7 on my rear 18x9.5-8 tamers

ill run 2.5 to 3.5psi depending on the terrain..

3 and a half... even 6psi? Are you guys insane? haha. I run my tires at 10-12psi.

you guys who run at a lower psi, do you have a buldge in your sidewall when your sitting on the bike?

with 6ply fronts and 4ply rears, if theres sag in the tires, i dont notice it...

for harsh trails, i cant imagine it any other way.. :D

Most tires are reccomended around 6psi MAX. I've always run 3.5 to 4.5 for trails, 3.0 dunes, and about 5.5 MX. (for rear)

I run a 330ex. 6-plys in the front and 4-plys in the rear. I run 5 psi all around (I like em a lil stiff, normal is 3.5 rear, 4.5 front, as the above poster posted).

Lil softer if you're riding muddy or sandy for better flotation.
A little harder if you're running hardpack/mx to keep from popping a bead in the corners.
