Hi, been a long time, Yes 15x8's, I had a set of 8" rally wheels on it but they were REALLY heavy, they had 5-1/4" backspace I think, went with the Welds but could only get them in 4.5' BS. so I cut the housing 3/4" each side and lopped the same off the ends of the axles [mosers with about 4" of spline]. Made my own offset spring hangers to move the spring hard against the chassis rail and now had room for 275/50-15 ET streets. Hope this helps
