So far (200 miles), I'm loving the Cooper ATP 275/65-20 (34") tires. With the OEM 275/55-20 (32") , when I was backing up with wheels at full right lock, I'd get rubbing on the wheel well liner, so I still have it, but no rubbing at all unless at extreme right lock. I'm going to try to zip tie the corner of the liner back and if that doesn't get it done, I am not scared of scissors. I have the Rancho Quick Lift at all four corners. The Coopers look a hell of a lot meaner than the SRA's. Man the SRAs are just craptastic tires. Already had two flats with them in 7K. The Coppers are just barely noticeably louder, but nowhere close to mud tires' constant hum. I was worried that I'd lose some ride quality going to the 10 ply, but the extra 1" of sidewall height seems to cancel it out- I can't tell that they're any more rough/ stiff. The best part is that Discount Tire Direct jsut had a deal on eBay for $100 off $400 purchases, so I bought two sets of two tires and saved $200 and Cooper had a rebate going so I will be getting another $70 back from them. All in all, I'm out $758 for the tires and $80 to mount and balance. The installer did tell me ahead of time that mounting them would peel off some of the plastidip around the edge of the rims, so I will either peel it all off or re-dip, maybe in black this time.
