Tire and wheel opinions

Not knowing what your rpm's are at the finish line I'll try to help . A 15"x7"rim with a backspace of 4-4 1/2" is safe . I would try M/T street radial inP 235/60-15 . I am of the opinion that you need a shorter tire to increase your rpm's . Start the "StickyMickeys" @20 psi and go down from there but stop @ 15-16 psi . Street radials don't require a lot (if any) water on a prepped track . good luck !
