I have a 07 vex 1800 with a champion trike conversion it has the original champion wheels on it and they are flaking badly I am having trouble finding some replacements as I am wanting to do an aftermarket polished aluminum wheel but mine are a 4 lug 115mm 8”x15” wheel does anyone know a website and the exact size I need to get because I don’t want to get the wrong size and I’m not for sure I measured them right thanks a lot
