Which E rated ties have the most weight capacity?

Nobody mentioned that the rims may not have the capacity for the chosen tire even if it fits?

I had 295/70/18 dick cepek tires E load with a 4080 rating also. They did fine on and off the road. I used them for daily driving and towing.

Same rating with Goodyear DuraTrac and Wrangler MT/R. Probably same with other brands too. Nothing special extra about the 4080 rating.

All E rated tires of the same size should have the same weight capacity.Here is a 4,080 lb capacity tire :

Last year, I bought Cooper AT3 XLT 295/70R18 which is 4080 per tire. With that tire you get an extra 440 lbs per tire for a total of 880 lbs for the rear axle. That translates to an additional 4400 lbs you theoretically could haul on the fifth wheel at 20%. These numbers are for a 2018 Ram 3500 with 18 inch tires.

They are only 1 inch taller verified (my brother has the 275/70R18's) and they are wonderful tires. As soon as my new trucks Firestone HT's get some miles on them I'll replace them with these tires. $1700 for 5. But that gives you some serious extra capacity if you are close on the rear. I run about 6900 on the rear and I'm good for 7280. An extra 880 lbs gives some serious headroom. 60,000 mile warranty. You have to have them force balanced. I may put on centrimatic balancers right away.

For the OP the 3200 tire is a D rated tire 3195 actually according to standards:

Tire Size LT275/70R18 Single Tire
35 psi 2070 lbs

40 psi 2270 lbs

45 psi 2470 lbs

50 psi 2680 lbs (C) 115

55 psi 2840 lbs

60 psi 3020 lbs

65 psi 3195 lbs (D) 121

70 psi 3360 lbs

75 psi 3530 lbs

80 psi 3640 lbs (E) 125

95 psi 3970 lbs (F) 128

8.1 Van, I agree but still waiting to be shown the capacities are different even in the same load range and tire size.

The tire industry has load/inflation charts for tire sizes that does not change by tire brand.

A friend of mine always said "prove it" and every chart you look up will have the same results!

To the OP...careful shopping for the same sized tire with the highest load rating. As some stores will only show you what they sell. Even though another brand might have a higher rating.

Do your research and make sure your wheels are also rated for MORE than the tire’s rating (personal preference), as the tire has more compliance than metal wheel will have.

BUT, none of this would be confusing if the OP did a little research on tires. They would presumably understand the conventions relatively easily.

This is where my confusion started. I was looking online at different tires. My 275 70R 18 firestone tranforce state 3640# at 80 psi on the tire. The ratings I would see online all listed around 3200. I figured they must be using a generic number.

The LT275/70R18E has the 3640 rating the tire with the 3200 is most likely not a LT and/or an E rated tire.
