slick size

26/10 15s if you have 15" rims.4.5" bs wheel will most likely put slick against the frame rail. D radials might not rub on the frame rail.You can use wheel spacers to move that 4.5" bs closer to 4" bs and they should clear inside and out.I assume you're runing 3.42 gears. good luck

Prior to purchasing the MT Drag Radials I contemplated a set of slicks. From what I've seen on the board, a 28x9 slick is as big as you can mount on a car that has not had the frame notched.

Im useing 26/10 15 mts on 4" bs rims. They fit fine.The wheel back space is where the problem comes from.To much bs and you rub the frame and to little bs gets the tire into the fender lip. a 10' slick fits fine otherwise.
