Title: Tire Pressure?
Post by: Fox17 on July 11, 2007, 08:49:54 AM
what is the lowest safe tire pressure you can run in a dirt bike tire? mine was really low and i rode it for a while not knowin it. then when i pumped it up, it didnt handle as good. the front was sliding everywhere. i dont want to keep it too low though. the tires dont say how low i can go though.

It depends on the size tire. What is your bike? You should never "air down" a dirt bike tire..very dangerous.

  10 is the lowest I would even dream of running, you do not want the tire rolling in the rim,  I always ran 20front and 25rear in my YZ 490 and 250's

I would break the tire down, as low as it got while riding you might have super heated the side wall. this will inturn destroy the tire from the inside out. for safety purposes take the proactive approach and have it inspected
