The stock wheels on my EXT are plain white disks. The EXT2 wheels I got are black with spokes. I mainly use my truck for bashing so it spends some time on asphalt and pavement as well as gravel and dirt. I may get some stickier tires if I ever find a track or make my own but I think I will stick with a longer wearing tire for bashing. I just don't want the wheels going to pieces on me. I figured if they used them on the BL EXT2 then they should be ok.
