Ok I have a 03 cobra pushin a lil over 450rwhp and street tires are suicide i have come to conclude lol.. So next year I am looking to pu some dragradials on the back on some 18x10 inch rims... Ok now people say nittos have the longest treadwear but have the lowest traction.. I am putting about 5k on a year and i am thinking the bf goodrich tires would work considering i already run t/a kdws and those would be on the front...What size should go on the back
Not going to be hitting the drag track due to the drop top, just fun on the street, shows, and some daily driving

 

With the 18x10's Id go with 315's. With the 9" rims, you could go with 315's too, but you wouldnt get the best traction or tread wear. So Id go with 275's for the 9".
