Jzap, the wheels are 15x7 with 3.5" backspace. They are a knock off of WELD wheels, I found them on ebay. The guy who makes them ( made them, they're gone now) had the centers and rims seperate. He made them to any backspace you wanted. They are VERY light, not paticularly suited for rock work
, but I use them off road all the time. Just got to be careful. The best part is I paid $80 each. PS, Nice looking rig, like the matching paint. Did the same to mine, but gotta admit, I got the idea from you!
