Cooper Discoverer AT3 XLT vs Cooper Discoverer AT3 LT — Compared

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!”

“Put some new tires on the XD today. Cooper Discoverer AT3 XLT in 275/70R18. I usually run BFG KO2s on my trucks but wanted to try something different this time.”

“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.”

“I have the Cooper Discoverer AT3 LT tires on my 2010 Tundra with Hawk. They are E series tires. Found this link that discusses the differences between the LT and XLT. Really like my LT's. The increased tire mileage would probably be a good thing of the price difference isn't too great. Paul”

“I got 80k (rotating every 10k) out of Coopers on my 2010 and have 40k on current 2019 SL ... Discoverer AT3 LT ... they are designed for heavier trucks... excellent noise, excellent in water. I got stuck in a grass field in the factory HT hancocks... same field few years later with coopers.. no issues.. never tried in snow but imagine they would do well...”

“From the Cooper site: Discoverer A/T3 55,000 Mile Treadwear Protection - Light Truck sizes 60,000 Mile Treadwear Protection - SUV sizes The Discoverer A/T3™ is an all-season, all-terrain tire designed to perform well on the highway and off for drivers of SUVs and light duty trucks. Excellent highway performance Excellent wet traction Improved treadwear and traction in rocky and gravel terrain M+S Rated Discoverer AT3 LT 60,000 Mile Treadwear Protection - LT-metric sizes The Discoverer AT3 LT™ with Durable Tread Technology™ hauls heavy loads with less wear and are built to withstand ongoing assault from dirt and gravel. Designed to prevent shredding on rocky and gravel terrain Extreme durability for hauling Superior control and braking in wet weather Cutting through the marketing-speak, it sounds like the A/T3 is more road biased and the AT3 LT is perhaps heavier duty and more offroad biased. And the AT3 LT is not rated for winter conditions. I've had Discount Tire try to feed me a load of BS on more than one occasion. It sounds like that's what they were doing to you. The A/T3 is definitely still available.”
