Odd Tire Wear...have a look

[OldCracker29]

I run 60 psi all the way around. The tire wear on my truck looks normal, with the exception of the back, which are wearing slightly faster than the front.

Aren't you running an 8-ply tire too through? My buddy's 3/4ton tires are rated and run at 50-60psi.

I think my tires are only rated for like 40-42psi max.

I think he does, I have load range E tires and I'm running 50 psi all the way around.

Jeff probably has E rated tires which are 10 ply and are usually rated up to 80 psi.

Jeff probably has E rated tires which are 10 ply and are usually rated up to 80 psi.

So E are 10ply.

What are D tires? Is 8ply the standard or 6ply?

D are 8 ply and Im pretty sure they are the norm as far as LT tires go.

Load range actually is not connected to how many plies a tire has or does not have. It's just the load rating of the tire. In fact, the ply rating is often not actually a ply count any more. Hasn't been since the days of bias ply tires.

Here's some info from TireRack:

The load range or ply rating branded on a tire's sidewall helps identify how much load the tire is designed to carry at its industry specified pressure. Passenger tires feature named load ranges while light truck tires use load ranges that ascend in alphabetical order (letters further along in the alphabet identify stronger tires that can withstand higher inflation pressures and carry heavier loads). Before load ranges were adopted, ply ratings and/or the actual number of carcass plies were used to identify the relative strength with higher numeric ratings or plies identifying tires featuring stronger, heavier duty constructions.

Today's load range/ply ratings do not count the actual number of body ply layers used to make up the tire's internal structure, but indicate an equivalent strength compared to early bias ply tires. Most radial passenger tires have one or two body plies, and light truck tires, even those with heavy-duty ratings (10-, 12- or 14-ply rated), actually have only two or three fabric plies, or one steel body ply.

Actually the C rated LT tires are the most common out there.

Mine are rated at 50psi and I run them at 50psi. No odd tire wear and great handling. this truck rides so much smoother then my 3/4 I had that even with tires at max its a million times smoother.

Found this on the 'net...might help explain tire wear..
