275/70-18's in SL or C Load Rating?

[Mightyquinn]

I've combed through most of the threads on here and have listed most of the major tire companies websites to look for 275/70-18's in SL or C load ratings and it's very slim pickings right now. I was curious if anyone else has seen anything else that I might be missing. I have a TRD Pro inbound soon and was just curious of what my option are as I would like a larger tire size if and when I decide to upgrade from the OE tires which I haven't heard good things about. So far this is what I have found.

Goodyear Territory R/T SL 39lbs (Factory Tire)

Nitro Terra Grappler G3 SL 45.6lbs
Toyo Open Country A/T 3 EV SL 43lbs
Goodyear Territory M/T C 50lbs
General Grabber A/TX SL 46 lbs


If I find anything else, I will update this thread but I'm looking for a good all around AT tire that looks good but doesn't throw off the ride and performance of the truck too much. I'm sure I can't be the only one who would want/need something like this as my off roading will be mostly limited to the beach.

I believe General Grabber A/TX are available in an SL rating as well. BFGoodrich KO3s are supposed to be coming out in a C or SL rated tire in this size at some point this year, and the Falkens are already available, but they’re super heavy.

I have the KO3s, and yes, they’re heavy, but my ride quality is excellent and they’re smooth and quiet on the road. I personally think some of the concerns about effecting performance are a little overblown. I have a base TRD OR, and in my opinion, I hardly notice any difference in the truck’s performance. I went from the stock 265/70R17 trail terrain tires to the 275/70R18 ATs, so at first, I could definitely feel a bit of a difference, but after having these tires on my truck for 4-5 months now, I’m actually shocked at how little they really effected my mpg performance, losing about 20 miles per tank on average (not too bad for a significantly larger wheel and tire setup, I think).

Sorry, wrong size.

I made the same upgrade as user @Kdbradley85, Non Hybrid TRD OffRoad I went with TRD Pro wheels instead Traihunter but they are identical 275/70R18 E Load KO3's. I really havent noticed a power difference and I get into the throttle pretty good. I was initially really concerned about weight as well but I think if you stick too 33in tires it's not really a concern especially since you have the Hybrid. These trucks even the non Hybrid's have tons of low down torque. Weight seems to start being more of a factor with 35's and 37's. Congrats on the Pro btw

I have 265/70/18 KO3’s on Tundra PRO BBS forged wheels. They are solid. Don’t automatically assume load E wheels are too harsh.

Exactly. I'm betting the Pro would hardly feel different, and considering that the OEM tires are already 32.6", going only 1/2" bigger and a bit heavier will probably have even less of an impact on fuel economy as compared to the non-hybrid setup with the same wheels/tires. I agree with the OP though, I still wish there were more options in this particular size since I think they're the perfect fit for these trucks. So long as everything is balanced correctly, the E load tires ride perfectly fine on these trucks, but if I had the choice to get KO3s with less weight on 'em, I probably would have. Although the heavier duty tires are nice for driving on job sites and rough terrain types. I've already managed to pick up a screw with these, and I'd bet the thicker tread helps them survive a bit better.

Supposedly we’ll have more C and D options by end of year. But you have to go with availability sometimes and the E loads I have are fine. If I was doing daily 100 mile commutes at 75+ mph, it might be different.

Even then I’d probably run Michelin LTX AT/2 load E’s.

BF Goodrich has a sheet of all upcoming sizes for the KO3's through 2026 and I didn't see 275/70-18's in SL or C load on that list. I'm still leaning towards the Nitro's or Wrangler M/T's at this point but luckily I still have time on my side as I plan to drive the OE's for a little bit and see how they. I will revisit the whole E load debate again when the time gets closer.

So I just picked up some method 316’s in 18 x 9 with 18 offset. I believe they are about 5 pounds lighter than stock rims. According to a tire rack guy, they will widen the stance a lot over the stock offset.Might have to get larger fender flares.

I’m looking for tires now and this thread has been very helpful. I’m considering the Toyo Open country AT3’s and the Nitto Terra grappler G3’s. The G3’s have best in class wet traction and good dry, they aren’t super good in the snow, but I rarely go into the snow and happily trade that for the wet performance. G3’s come in SL and E, but are 46 pounds in SL. Toyo’s are 50 lbs. I understand oem trail terrains I have now are 39lbs so there’s no way to avoid increasing weight.

Anyone try these? If yes, what did you think/recommend.
