Tires on the '93 are due. Maxxis Bighorn MT in 315/75r16, and they are close to have given their all.

Browsing 4WP and DiscountTire, I see that most 315s nowadays are rated 'E2'; there appear to be very few offerings that are 'D".
I've always ran D-rated tires, and thought E-rated tires are for trucks that see towing duty or carry very heavy loads. So the idea to go with E-rated tires is alien to me, but there are more choices at 'E2". The '93 isn't that heavy (~2" lift, 315s, Slee front bumper + HF12k winch w/ synthetic rope, WKOR sliders), and I want sidewall flex and traction. No towing duty.

Does anyone have real-world experience (I've perused the load rating tables etc. so I'm aware of numbers ) in comparing E1, E2, or D2-rated tires?

Did you not like the Bighorns? Why not get another set of those?
 
I've run E-rate tires on my 93 for a couple years now. If you're not concerned about sidewall damage, stick with the D's?
I peruse tires quite often and haven't come across the 'tiered' designations before. E1 & E2? News to me.
Happy trails!
 
I really wanted D's because I thought they'd be more compliant, but they were hard to find. I ended up with Goodyear Duratrac's in E and I have been super pleased with them. They get super soft when aired down.
 
I sell tires and have never seen E1 or E2, normally just C, D, E ratings. You will have a hard time finding D rated tires in that size. My 285 Toyos are E rated and they flex well offroad. I would just get what you want and air down accordingly. The E rated tire should be tougher and last longer but still flex when aired down.
 
The Goodyear MT/R is D rated in the 315/75 r16 and a high quality tire.

D rated is more than sufficient for a loaded 80 series. It will also ride more comfortable.

I ran the GY MTRs (both generations) in 315 for many years on my K5. I really liked the grip I'd get from those, wheeling primarily around Phoenix, and in southern UT; I'd start to get cuts after 3-4 years. Availability of replacements was a constant issue at that time; I guess GY only make truck tires when they feel like it. So I haven't looked at GY any longer. When I went to 37s on that truck, I went with Toyo R/T (didn't like the sidewall flex on those).

The Bighorns have done well, and I tend to stay with them; price is great, as well. Last summer I put ProComp XMT2s (37s) on the K5, and really liked how well those tires worked in the rocks on a recent Johnson Valley trip. So I looked at ProComp 315s for the '93, and that's when I came across the issue of 'E1' vs 'E2' vs 'D2'; the ProComps are 'E2' for the 315 size.

Here's Discount's link to Load Rating/Load Range:

Ah, it just indicates the max pressure. Either should be fine. I've never seen an E2 (65 psi).. All of them I have done is 80 psi.
 
I have load range e tires on the truck and I have no problems with them, ive never seen an e1 or e2 rating but they would both be 10 ply tires and the only difference is the max tire pressure. I wouldn't worry about it being an e1 or e2 get what ya want and run it
