What's a really good 33' all-terran tire?

Hankook makes a good one. General grabber at2s are good. cooper at3s are good. Depends what you prefer I guess. Im assuming you have 16 inch rims, which means a 285/75 would be really close to a 33(32.8 inches), just in case you can't find a 33 in those brands.

Ill second the grabber AT2's they are nice. i run 33x12.50 toyo open country AT's on my ram 3500 cummins SRW, ive had them for about 10,000 miles and they show no signs of wear. my set was $1250 with tax only because i opted to go with specialty 12 ply over the average 10 ply and also my wheels are 17, youve prolly only got 15 or 16's. i think you can pick them up as 6 or 8 ply for about $800 a set.
