Deal Alert: 275/65R20 Cooper Discoverer AT3 XLT - $219 ea

[johnnylawson]

I've had these tires for 10,000 miles and love them. Load range E, which means the operating tire pressure is significantly broader than the OEM's. I run mine at 65psi (80 psi max) and my range is practically identical to OEM. I've written a number of reviews on them....comfort, traction, on and off road performance.

How they holding up now? I just ordered them on tirebuyer.com and having them installed right around the corner from me.

My deal I put together:

Then minus another 6% off using Microsoft Edge browser cash back, then - 100 cooper tire rebate. the -150 on picture is RAK10 coupon code.

The total basically comes down to 1388 for these with tax and install. PRetty gooooood deal!

21,000 miles. At least 10K treadlife remaining. No odd wear, still reasonably quiet. I've had A/T's from 30+ years from Cepaks to BFG's and everything inbetween and these have been fantastic for me on my truck. Run them between 60-65psi to recover efficiency losses.

I know lots of variables but what's it saying for you for range on a full charge? And what percentage is a full charge for you? Thanks

Finally got them installed today - running 68psi (max is 80). So much quieter so far

They look great and it's glad to hear another owner commenting on tire noise. They are more beefy than the Scorpions, but must have engineered the rubber and tread pattern quite well for noise and longevity!

DISCOVERER AT3 XLTLT275 /60 R20 123S E1 BSW ~ is this the correct specs?

That is correct. These are still quiet at 31,500 miles. I think I will get 40,000 out of them.

Thank you!

Sorry is it 275/60 or 275/665. Postcard 275/65 but my link had it as 275/60. This is so confusing for me. Planning to get some forged wheels 20” to use with these tires

Glad to hear they are quieter. Looks great. How is the ride quality at 68psi compared to scorpions at the stock 48?

I’ve been running Discovery AT’s for years and have 3 sets of XLT’s on ICE trucks and SUV’s. I love them so I’m glad to hear they are doing great on the Rivians. This will be my replacement for the Scorpions for sure now. My suburban has about 40k on the XLT’s and is as quiet now as the day I bought them. I’m pretty religious in rotating but they should last another 30 or 40k on the suburban. 40k on the R1T will be great.

Same if not better. Never stuck out to me as bad. Got 24k on them now and holding up well and still no increase of noise.

Just checking in here and I'm at 50k on these and got another 10k left I think. Going to buy again when it's time!

Pretty impressive if you can get 60k! What’s your MPK? If it’s anywhere close to 2 then that’s very impressive…

I had these on my R1S a year ago. The steering had a wobble above 45 MPH. Tried balancing again but didn’t fix it. Discount Tire swapped them for a different brand/tire and the issue went away. YMMV - I don’t have a lot of experience with A/T tires so I can’t draw comparisons but I didn’t like these at all. They felt very sluggish and my foot had to stay on the accelerator a lot more compared to A/S tires. Maybe that just comes with the territory for A/T tires given the higher rolling resistance?
