Ok so I found a really good deal on some tires. 295-70-17 NITTO TERRA GRAPPLER but they are load range D not E. What really is the difference and should I be worried? I am not hauling anything heavy or really hauling alot at all.

Thanks

D load range tires are 8-ply and have a max inflation pressure of 65 PSI. E tires are 10-ply and 80 PSI. For a given size, the E range tire has a considerably higher load rating. Personally, I would go no lower than E range on a 3/4 or 1-ton truck. Higher ratings usually give you less rolling resistance and more tread life as well.

 

I agree with Joel your truck came with E load tires for a reason. The D load are going to feel squirmy as well.

 

I had Firestone Destination ATs 285/70/17 load range D for about 20k miles. Load rating on the Firestones was the same as the load rating on the E 265/70/17 BFGs that came with the truck, although lower PSI. I towed frequently and they never felt squirmy but I check tire pressure BEFORE I tow EVERYTIME. The only reason I changed is, like the BFGs, they were aweful in the sand. I would agree that you should use E rated tires, but not manditory. Remember, load rating is more important than load range. In my case, larger tire with lower PSI = same load rating.

 

I always stick with "E" tires.

 

I agree with nick d rated side walls don't hold up nearly as well if load is applied.

 

I had 10-ply tires on my truck in the stock size, but I wanted to go bigger so I went with 8-ply 33"s. I also put on new rims, though, so I kept the 10-plys if I ever need to haul. I towed the biggest U-haul trailer from Seattle to San Diego on the 8-plys with no problem though.

I think you'll be fine if you're not carrying too big a load, just make sure to air up the rear tires to the max pressure for a load, D or E tires.

 

I ran load range Ds and they werent as fun to drive with weight. I also got worse wear. Ds will wear faster.
