The car has 17" rims, 12" wide.
The need is for streetable rubber. For Road Race tires; I think I have more options.
Im thinking about going to 18s or 19s in the rear, that would open up the options considerably.
When I did this, I intended to run 390x710x17 treaded DOT legal race rubber in the rear. I guess I took too long building the car; they have obsoleted that tire size and I cant find them anymore.
My remaining options for wide 17" rubber is 335 series radials (not enough sidewall to look right in these wheel openings), the M&H I just mentioned (would look right, dont know about the rest), or the Mickey Thompson Pro-Streets...which are 31" in diameter...which will make the rear look pretty weird. Probably OK for straight line, but they wouldn't corner.
So, there's the rub.
