Ok im buying 265/75-16 tires you can get them in a D or E rating. I know that one will hold more weight than the other but is there some reason to get the lesser rated tire? ride different? they are pretty much same price like $1 difference. Nitto AT or BFG AT

Its going on 98 chevy full size, ex cab, 4x4, but 5 speed no power windows/locks, bench seat and only the 305 so it prob is a little on the light side.
 
correct me if i am wrong but i think the rating determines what the maximum speed is the tire can handle, i would go with the e rating.
 
on passenger (P-P175/55/15) tires i think they are for speed, on light truck (LT-LT265/75/15) tires, i think it is for load rating. i think that it is more of a towing rating more than anything else.
 
B-F are load range ratings (M-Y are speed ratings). D are 8 ply and E are 10 ply. D are 65 psi and E are 80 psi. I had E's on my Suburban once and the tech said I could run them at 70 and it would give me a smoother ride. I don't know about the smoother ride but just like running any tire under pressure the tread wore on the outside faster than the inside. I have different E's on my burb now and I like the way they handle. I don't really like airing them up to 80psi though. Sounds like you could go with either and maybe not know the difference.
 
You'll be fine with either, thought the E rating will be a stiffer sidewall and tread construction to better handle the weight. For comfort, I'd go with D.
Just my $.02
 
The only true way to tell load capctiy is with the load index, service numbers on a tire... load rating is really an older scheme when actual rubber plys were used, its a good indication of capacity and ply 'rating' but not actual plys used.

A tire with 2 ratings is for its rating when used in a dual applicatoin,
for example my D - rated BFGs are 119/120 a dual would be 119 (each) and my Single tire would be rated at the 120 value.. (at the spec'd PSI)
