“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.”

“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. Im 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 dont want to trim anything and dont 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.”

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.
