I recently purchased a used racing go-kart. One of the tires had a small sliver of metal in it and is leaking air. The tires are Burris racing slicks size 10 x 5.6-5. This seems to be an oddball size as I have not had any luck finding a replacement. Does anyone know if another tire size will fit the rims? The rims are ARC ( I think) split rims.
