I went to buy a tire Pryr look-alike and I had to choose the one for 5″ or 6″ wheels. To find out, I checked my builder’s sheet and I have KG Aluminum 170mm and 140mm wheels. I went to look this up and a website says there is no company called KG. The wheels I see on Kart retail websites don’t come in those widths either. Kind of makes me feel a little concerned I can’t replace a wheel if it gets damaged.
