“COOPER DISCOVERER AT3 XLT / NO STUD / 32.56" / 54 LBS / 3 PEAK / $265.99 This is what I came here to suggest ^ BFG also has the KO3s coming out soon right? Pictures KO3s release for Spring 2023 Patagonia Milestars are also pretty great tires I hear, but I've never had them. They are a subsidiary company of Nankang, made in Taiwan.”

“Quote: Originally Posted by Stadt This was while I was running a ReadyLift 2.25" level only. The ride was good with only the level, just normal body roll and bed hop. Upgrading to the Bilstein 6112 and 5160 made the truck handle much better. You can gain this same set up with Bilsteins as well. The 285/65R20 did not rub unless the suspension was flexed, but under normal driving conditions, no issues. This tire size is perfect for a 2" level while running the stock wheels. Aftermarket wheels will require a smaller size, 275/65R20 is typically largest before significant rubbing. 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 figure any tire review is good, even if late. I'm nearing the end of use for Cooper Discoverer AT3 XLT in LT275/70R18E 125S on OE 18x8" chrome clad wheels. They have been fantastic tires , great in the snow, quiet, never felt like they were giving up any traction except for the fourth (last) winter, but they never felt dangerous. They wore dead flat across the tread, kept the fronts at 65# and rears at 75#, rotated about every 5k miles, used Thuren alignment specs. They made 50k miles (the warranty in 2020) no problem. I have no problem getting them again or recommending them, but I like trying something different. If the different tires I chose this time don't work out (45 days), I'll just get these Coopers again.”

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.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
