In the near future I'll be switching out the GY P-metrics for some LT C or E load. Does anyone know with certainty the maximum PSI rating on the factory 18" wheels?

Thx

 

They will handle anything the tire will. Just make sure it is the proper pressure for the tire. For a LR C probably around 40-45. For a LR E, depending upon the tire, anywhere from 40 (for high load carrying ability of around 4000lbs per tire) to 50 (for normal LR E load carrying ability of 3200 to 3400lbs per tire).

 

Max on a load E is 80psi which is over kill for my axle but I need to know what the safe limits are for the wheel. Will they take 65psi if I need for towing?

 

They will take anything the tire will take, including 80. And 65 would be overkill, even for towing.

 

80 is the max, if you put 80 in when they are cold you will be over 80 psi. I have the bfg ta ko and per bfg they recomended 50psi. That psi will handel anythign your truck is able to tow same with stock rims.

 

What is your concern with the wheel?? The wheel itself is probably pretty limitless on pressure; you're not going to blow the wheel apart, so I don't think we know where you're going with this???

c1t1d1...as for your comment, max tire pressures are cold specifications, not a hot limit or absolute max limit. Yes, Ina sense you are correct, if you pump a tire up to its max and then it gets hot (in the case of you example, 80 psi) then it's OK if the pressure builds up above 80, the manufacturer has accounted for this...thus the "cold" setting. Also, when you run a tire at those higher pressures, the tire is actually going to run cooler. If you take two tires with a given set of conditions and run one at the max 'cold' psi and the other at a lower psi, the one at max will not hear up near as much as the other. There are a list of problems from running a tire overinflated, but overheating isn't one of them.

 

Good answer!

 

I keep my 305 BFG TA KO at 45.
