using tubes as wheel spacers?

hey guys, i want to run some wider wheels, and according to my calculations, the new wheels have 3 inches more of backspacing then my old ones
so, to keep the tires out of the frame, i figured i could install some longer studs and cut some tube to use as spacers
as long as all my tubes are close to the same length, and i bump my wheel studs up to 5/16th i should be good right?









Wheel Spacers in general are a terrible idea! Buy the correct wheels.




























almost forgot to mention, im talking about a 5.5 hp go kart, of course
