What load rating do I need on a size of 315/75R/16 tires for my lifted truck? I think I saw it was E. Seems a lot of tires I am interested in are only Load Rating D. What are your suggestions?

 

I think you should figure out the weight of your truck along with the max load you plan to carry first. My truck came with E's but the winter tires are D's. I just know the load difference and don't exceed it when I have the winter tires on.
Your tire shop should be able to help you out with your decision.
Good luck.

 

A tire shop will try to sell him the more expensive E's. And since the truck came with E's from the factory, they might not sell him D's.


Mike, you said your truck is lifted. So I can assume you don't tow heavy or haul heavy in the bed? D's should be fine. A load range D in the size you are looking at can generally handle 3200lbs each.

 

A lift has little to do with what load rating you should use. As stated it depends on the GVW you'll be running.
A lift, if it's high enough, might have a very slight bearing since the CoG is higher, but it's likely a minimal affect.

 

Lifted trucks suck for hauling stuff...either in the bed or on a trailer.
Generally, someone with a lift doesn't load their truck heavy for one. And generally, aftermarket lift springs (if he has them) are not rated for the same load as factory springs. They are tailored towards flex and ride quality.

With D's the OP can handle a RAW (rear axle weight) of around 6400lbs give or take a few hundred depending on the tires. The OP's rear axle (Sterling 10.50) is rated for 9,750lbs. Only the OP knows how he will load his truck...

 

Right, that's why reiterated that the load rating depends on the expected maximum GVW he'll be running, which is really all that can be said since there isn't any relevant information posted about his setup or how his truck is used.
