I have been looking at tires and comparing sizes and load rating what is the difference between a tire rated for 3100lbs at 65psi compared to one rated at 3100lbs at 80psi. what about load rating comparison like C D and E.

 

If you are towing do not even consider lower than 80 pounds pressure capacity.

My stock Michelins were 80 psi "E" tires.
My current BFG's are 50 psi "D" tires.
According to the sidewall they both can carry the weight.

The Michelins looked "full" at 65 psi.
The BFG's look low at 50 psi, the maximum.

I wouldn't try to load my truck down with the BFG's on it, I bet they would blow before I even got on the road.

They sure look nice though. 8)

I will be getting "E" rated's the next time out, an inch or two taller even.
I'll pay for it though, planning on twice as much per tire.
Parnelli Jones dirt grips, the only "E" rated 37's I've seen.
