I would like to buy tires to go on the track with my Challenger.
It's a street car but want to go to on a real track this summer in UK ( SantaPod ).

416 ci with weiand Xcelerator, 727 with Transgo TF2, rear end 3.73 + Gear vendors.
I shift at 5800-6200.
Converter is 2500
Edelbrocks heads with 0.525 camshaft and 237 duration. prosystem carburetor 850 cfm DP

Today my best time with street tires, Avon CR6ZZ, track was not good.
diameter of tire, 27", 275x55x15.

13.02 @ 110 Mph, 60'@2.25

What diameter and width do you think?
And Slick or quick time pro?

thank you
