I know, someone is asking another stupid wheel question, but I have to. I have 13" chevy wheels and wondering is the center section the same as 14" or 15". Talking about the section welded to outer rim. Was think of putting spider rings on, but nothing for 13" rims. Don't have 14" or 15" rim to measure if any difference. On Wheelkid web site, they list a size for rings, not sure where their measuring at on wheel. Also, on the push through cones, do they push through the hub center and if so how. When the wheel is bolted on, the rim fits up tight to the hub and axle st the center hole. I know, i should just contact Wheelkid, but I was just checking with some of you guys real quick. Sorry for the dumb questions, and thanks for any replys. P.S., just trying to dress up the steel rims I already have and save myself some cash.
