So... LT315/70R17 113/110S C or 35x12.5R17 Both BFG KO2's

Any advice on which to choose for a 1500 4x4, used as a daily driver as well as off road (nothing harsh sand/mud trails in Florida). They will be going on ATX mojave 2's (9 inch wide) rims. Occasionally towing a 5k boat.

I know both will be infinitely better than the current stock wranglers. The 315's are about 60$ cheaper each. Truck is will be leveled with bilsiteins at 2.1 or most likely 2.8 they are going on the same time as the tires.

I think they both measure out to 34.5 diameter, any reason to go with the 35's vs the 315's in this situation? load rating on 315's is 2535lbs vs 35's at 3195lbs thats the only real difference I can see, but most of you have way more experience with these tires than me!


Thanks!

Guess that’s a wash then. Some are much different. I was looking at 35’s or 295’s and the 295’s were like 10lbs less or something. Only other thing to verify is the speed rating but it might be the same.....

Went with the 35's, called 4wheel parts, they lowered the price to 4 bucks below the 315's each since they had the 35's in stock, free mount/balance, no sales tax promo, and 100$ rebate from bfg.


Thanks for the input!

Ran 35x12.5R17s on my 12’ 1500 at 45PSI F&R and on my 15’ 2500 at 55PSI Front and 50PSI Rear. Love them. They do great in all terrains that I’ve put them through.

Glad you went with the 35s. My local discount tire had both the 315s and 35s in stock. Side by side, the 35s look a little bit bigger. It's not much, but there's a difference.

Yeah I'm happy with the decision, now just hoping they fit with no trimming, the shop is concerned they might have to. But from what I read here they should be good, plus the bfg is really a 34.5in tire.

That's good you went with the 35s. I have 295 70 r18s which are suipposed to be 34.5 but on the truck they only measure about 33.5"ish I was kinda disappointed I didn't go true 35.
