I researched wheels a bit, but it seems that the info on whether we had to have the acorn nuts, hub centric wheels was debated. Anyway, i was pulling my Welds of and putting back the factory ones for winter (don't laugh, in MI it comes fastwer than you want). Teh Welds do not have the hub centric, acorn lug nuts. I have never been thrilled with the ride on the Welds, but attributted it to the fat 305/55/20s on the probably too narrow for the tire 20 x 8.5s. Where are the experts on whether we need thehub centric with acorn nuts?
