Tire and wheel questions

Thanks for the advice guys. Also if you didn't notice my link in the first comment, I found a set of American Racing Torque Thrust D's that I have my eye on, and they're from Newstalgia. The car will be more of a street car, and plan on running drag radials. I have a Buick Grand National with 235/60R15 and they really hook! Hopping to get that kind of traction with the old Fish, especially with the new motor I plan on building.
