Cooper Discoverer AT3 XLT vs Cooper Discoverer S/T Maxx — Compared

“Cooper Discoverer AT3 XLT Picked up a set of Discoverer AT3 XLT from simple tire. With the 4th of July discounts all 4 were under 1k before taxes. I had the AT3 4S on a previous ram and they held up so I’m expecting good things here.”

“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.”

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.”

“Interesting, I'm considering a Cooper Discoverer A/T3 Sport or Discoverer S/T Maxx in 245/70r16 for my Nissan. All of the reviews are excellent and have been recommended from friends using both types, one on little Suzuki Jimny and one on GC 2.7 diesel. According to them they are great both on pavement and off road, with GC driver being long time off roader.”

“I have 285/75-r16 on my f-150 and love them. I've put them through hell (rocks, mud, sand, rim breaking in half and truck skidding down the road on it) and the have held up amazing. My old set of cooper st's last around 60k and still had a little life left. Ill never run any thing but coopers now. and for the record i had that tire checked out by 3 different tire shops and they all said it was fine.”
