Tire size and availability

[Hunterred]

I am looking at getting new tires for my 2015 GMC Sierra 1500. They are currently the Goodyear SR/A that run to 51 psi and 1120 kg (2400 lbs). The thing is the size, 265/65/18. The only LT tire I can find in that size is the BFG all terrain AT2. The RAWR is 4300 lbs so a solid P rated tire will keep above that. My question is, what are other guys running in that size? Or am I better to step into a 275/65/18 that is a little heavier, wider, and taller, but comes with greater selection in a 10 ply?

I missed where the op asked for brand advice.

Thanks for the replies, I'm thinking the coopers might be the way. I have run cooper a few times and have had great success. We have a tire in Canada called the AT/W that is supposed to be good in winter. Gonna have to step up a size to get the LT model though but I think that's about my best bet.

If purchasing Goodyear I recommend the top line Goodyear Wrangler® All-Terrain Adventure With Kevlar®

If you live in Canada and drive in snow, do you really want a wider tire?

If I remember correctly, the Cooper A/T3 is also available in a LT 265/65/18. But if you have the 3.42 gearing, I would just go with the 275/65/18. That's what I did on our '10 Chevy 1500. Never noticed a difference in acceleration or anything regardless if towing or not. And the 275's were cheaper than the 265's by a fair amount!!!

I agree a LR E is not needed, but I would probably still go with a LT LR C. That's what I put on my '10 and was very happy with them towing ~7200lbs with ~920lbs tw.

The Cooper A/T3 have a mileage warranty even in a LT model. And performance is awesome with it!!! In all conditions (except mud- didn't venture off into that!) they performed very well in the 11k miles we had them. The reason for only 11k miles is we stepped up to our current 2500HD. Not sure what part of Canada your in, but in traveling to Northern Michigan and the Sault Ste Marie, Ont area for snowmobiling, I never second guessed the A/T3's. They performed beyond expectation!!! I will probably be putting a set on this fall to replace our factory pos SRA GY's. Still trying to decide for sure due to wanting to go to an ever so slightly bigger tire, but the selection is limited in a 20" rim...

My buddy has been very happy with the Toyo Open County AT2. They also have a mileage warranty in.

Good luck deciding!!!

There is NO reason to go to a LR E 10ply rated tire on your truck. If the P rated tires are doing fine, then stick with them. Just choose a tread pattern that fits your driving habit.

My sons put LR E tires on a GM 1500, and a Tacoma Tacoma, neither puts more than 40-45 lbs in the tires. So a P metric at 51 would be fine for them too!

I'm using the BFG all Terrain but I have a heavier truck and we do go off road. I've been very happy with them. Have you checked out Tire Rack (online) That site will give you a good idea of what's available.
