Guys, Thank you all for the responses; I appreciate the suggestions and vender references. Some more detail on the Cobra we have; it is a 1990 Butler / Arnst built Cobra with a Dan Fodge built engine and Jaguar rear. It has Halibrand spinners, but I haven't found any manufacturer markings on the wheels themselves...but the wheels seem to be pretty light weight when I pick them up. I'm sure the 6X15 and 8X15 designation on the existing track tires are a reference to the rim width rather than the tread width. I'll try to post a couple of pictures
