“275/60r20 General Grabber A/Tx Just thought I'd share what my truck looks like with a slightly larger tire size in case anyone wondered. No level, just stock. Good looking tires in my opinion.”

“Cooper adventurer (pep boys exclusive version of the discoverer), and then Cooper discoverer at3 xlt have been the tires on my tundra for the last +10yrs. I have put 80-100k on each set. I tow a smaller camp trailer regularly. They discontinued that tire, so I'm going to try the stronghold AT next.”

Tire A

General Grabber A/TX

Positive

Community sentiment toward the General Grabber A/TX is largely positive, with owners frequently praising its winter traction on snow and ice as well as its quiet highway ride. Buyers appreciate its availability in lighter standard load ratings and competitive pricing compared to rivals like the BFG KO2. Minor drawbacks cited include fuel economy loss with heavier LT versions and a tendency for the tread to pick up and fling gravel rocks.

If I had one complaint, I run a lot of gravel roads and rocks will stick in the tread. When I get up to highway speed the rocks come out and come out hard. I have factory rims so my tires don't stick out beyond the fenders except a tiny bit. I have a couple nice rock chips on the side of my truck from that.”

“Thanks Coldcase, you always come through. Im thinking of going for the General Grabber A/Tx, 1 vehicle from the link you posted is using them and even a bigger size at 285 without any issue, difference is they have the altitude package instead of Overland. Do you think ill be fine?”

“New Cooper Discoverer AT3 XLT 275/75R20 these ride way better than my old Open Country A/T II”

“Quote: Originally Posted by SodiumMonkey Thanks for the reply. I actually read through your entire build thread last night. Wow. Awesome stuff there. I’m planning on keeping the OEM Platinum trim 20” wheels. So I could run the Discoverer AT3 XLT 275/65 R20 without any rub at all with either a 2” spacer level or something like this kit from Fox? I don’t want to trim anything and don’t want any rub even when suspension is flexed. It seems like most info online indicates a 33” tire is the max for a 2” level and no rubbing. I believe the 275/65 R20 is a 34” tire. Thanks for the advice! I only ever rubbed with my 285/65R20s when I was reversing and turning right down an angled driveway, on the street and flat ground it never rubbed. Offroad is where I had the most rubbing but that is expected. A 275/65R20 is what a lot of people run with only a 2 inch level. It fills the wheel wells nice and it will very rarely rub in any on road circumstance, no matter how you level the truck. A 33" tire is too small in my personal opinion.”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
