Doug Schellinger posted some good info about NASCAR's allowed tire sizes in this thread:

In case the link doesn't take you right to his replies, here's the two sections from that thread which addresses tire size:

Max rim size for 1969-70 was 15 x 9 and was expanded to 9.5 in 1970.  The wheels have double welded centers for strength.    The size was 8/8.25 x 15.  Max sidewall width was 12.2"   The "tread" was kind of a hen scratch pattern.     Period Goodyears have a small letter pattern.    Anything with a large white "GOODYEAR" is circa 1972 and later.    You can still get tires in that size.

The K & K has seen actual track use in recent years, so it runs a modern set of race tires.   NOS sixties race tires are hard to find and require tubes.  Probably a good substiture is something like a Hoosier Street TD blackwall and copy the Goodyear markings onto them.

And another quote from the same thread:

That's the old time tire size.  There is a Goodyear Vintage Bluestreak available which should be very close.  It is an 8.00-15.  Fits a 15 x 10" rim,  26.5" diameter,  tread width is 10.2".  Section width is 12.9"   About $230 each   They have the original style tread pattern.    These are supplied for vintage Trans-Am racers.      www.sascosports.com
