Bad on the side wall my friend

 

12 ply i was aired down to 20lbs for some wheelin and ended up getting a pinhole in my valve stem and then when i went to air back up the tires looke fine but the one tire was down to 6lbs

 

i got 10 plys on mine...i check the air twice a week, for i want to get long life out of these tires (expensive)...pressure always the same........they call fo 80 lbs. but i have 40 lbs. in them, is that not enough?

Yak, Ive replaced all my shocks 5 months ago. when i bounce it and let off it stops bouncing instantly, aka shocks not bad

 

40 lbs is too much, back down to between 30 and 35, your gonna wear the centers out that way bud. 80 lbs is what the MAX tire pressure for the tire is....not what you should run.
