How low can I go ??

[88Silverado]

How low can I safely run Interco's off-road?
I have the TrXus M/T 33x12.5x15 on Weld 15x8
Im not familiar with these tires and dont know how well the sidewalls hold without popping a bead on this heavy of a vehicle.

Looking for a ballpark number. 12-15, 15-20psi ??

Any thoughts?

I say you can very safely run 12-15 psi. Peolple on here run much lower pressures with no bead locks. Swampers have prtty thick bead areas and sidewalls. If you have ever taken them off the rims they can give a tire machine a workout sometimes /forums/images/graemlins/thumb.gif Just make sure you have a good spare if you are worried /forums/images/graemlins/thumb.gif

I have 36x12.5x15 TSL's and run them at 8-10 psi on the trail and i've been as low as 4psi in the snow with no problems. Oh they are on 15x8 rims, no locks.
