Need Help With What Tires To Buy For The Track

[No Such Luck]

I want to pick up a set of Weld RT-S wheels and Mickey Thompson Tires. What is the best combo to go with?

For the wheels, should I get the 15x8 or 15x9?
(I have an IRS, I will just grind it down)

For the tires, should I go with ET Streets or ET Street Radials? Do I need a tube with ET Streets? What size tire should I get?

The car is making 601/586 with a Whipple if that makes a difference.

Thanks for the input

I would go with bias ply et streets and bias ply fronts. The bias ply tires weigh less, should be easier on the IRS due to the softer sidewall and your car will be quicker with them at the track. And you don't need tubes for et streets.

Thank you for the info.

Do you think an 8in or 9in rim would work best?
