Rim, Tire and Air down Question.

[SF87K5]

I have 36x14.50x15" TSL radials. I am buying a set of 4 15x12" rims from a buddy of mine.

My question is with that wide of a rim on a tirs as wide as mine. Could I run 15-20 psi in my tires will I am on the trail?

I run mostly mix trail, rocks, mud, sand. I will be going to Uwharrie alot also. Cuz its only 1 1/2 hours from my house. Plus hopfully Tellico next year.

Thank you in advanced for your help.

I would stick with a 15x10, but thats just my personal opinion. I have 35x15.50x15 TSL on 15x10's and have aired them down to 11psi with no problems on rocks.

15 psi should be ok with a 12 wide wrapped in 14.5 ...

As a general rule I run a size skinnier rim than is recommended for that tire. I would rather have the rock hit the tire than the rim. I run 15X8s with my 38X12.5 TSLs. I run em at 10 psi and never have em come off or get scratched but IMHO I wouldn't run the 12s. I bet they will run at 20 psi though if you want.

<font color="green"> Start at about 15 psi, shouldn't be a problem with that. Go down another 1 psi on each trip, as soon as you blow a bead then you know that you've gone too low. Add a couple psi on top of that number and that's pretty much as low as you want to go without the risk of blowing beads all the time. </font>
