Well it was time for new tires and after much research, I decided to purchase the Cooper Discoverer S/T in 265/75R16. I gained 1" of clearence thanks to the larger diameter and the fact the 245/75R16 Discoverer ATR's were completely worn down.
Here are the before and after pictures:
UPDATE:6-16-08
I am impressed with these tires. Since purchasing them in April, I driven through snow and rain covered roads, made a couple trips out to the desert and a road trip rockhounding south of Jackpot, NV. What a huge incrase in traction from my old Discoverer ATR's. These tires offer a lot more grip over the ATR's, and the same amount if not more than the BFG AT's I had on my Jeep. Granted vehicle dynamics are at play here too, but I do believe they may be better.
Here are my impressions:
Pavement: The noise from these tires isn't as bad as people make it out to be. It peaks at 55-65mph and then the general wind noise takes over. The reduction in pavement traction is noticible in corners and cross winds on the interstate, we usualy get gusts up to 40mph. In all I am pleased with the pavement traction.
Wet Traction: Wet traction was quite good and I have not experienced any hydroplaning as of yet. I believe this is due to the radial voids clearing out water.
Snow Traction: Not driven enough to know
Off-Road: I am really impressed with the traction of these tires off-road. Believe I have only had the tires slip once and that was while crawling up a mud and snow covered trail to one of the near by buttes. They really just dig in and go. Times when I figured I would get some wheel spin, they just crawled right up. So far I have had them on dusty desert trails, rocky mountain trails, and loose gravel roads. They do throw rocks, but I don't believe as bad as my old BFG ATs did. These tires rock!!!
