How much Air in new mx tires?

[bean86]

Alright guys, they just opened a new mx track around town here and this is a very big deal beause it is about the only track in a 150 mile radius here in Northwestern Kansas so i am very excited. I bought brand new 18X10X8s Maxxis Razors MX Tires for the front and rear for my Honda 250R on .190 gauge aluminum wheels. What air pressure should I run so i don't bend my new wheels. I was thinking about 6 or 7 pounds all the way around. Also the track has some nice doubles but the longest jump is probally around 50ft so nothing to extreme. Any info would be great. Thanks

so you bought the same size tire for both the front and back?

I would say 8psi front and 10psi rear. Then adjust from there at the track.

im no mx rider, but I hardly run any air pressure in my tires, i'd guess like 3 or 4 psi at the most in the back (4ply 20inch razars) and about 5 or 6 in the front (23inch holeshots). but all I ride is trails and from what I noticed the less air pressure you run the softer the ride.....to a certain extent. iver tried riding with 7 or 8 psi and it would beat you to death on real rough trails.

No i am not running the same size on the front and the back. I just listed the back because they could be 8 or 10 in rims were all you can get in the front is 10 inch rims. I was just lazy and didn't feel like typing it all. I get the 20x6x10 Maxxis razor MX for the front.

like someone else said run above 10 in front and around 8 in back aand then adjust as needed on the track
