For stock wheels, use 90/90/21 Front and 120/18 Rear, Avon "Gripster" tires. You won't be close to dragging your knee, with sock wheel size and suspension though. (*NOTE Keep your weight foreward on the bike at all times, or you will chatter and push the front, mid-corner)
For 17" wheels, call Buchanan's Spoke and Rim, in Azusa CA. (909) 555-1212 then when you get them, mount up a set of Dunlop 120/60/17 D208GP Star front and 150/60/17 D208 GP Star rear "Dot" race tires. If you actually want to drag your knee, lower the bike 2" and use 120/60/17 Dunlop KR-106 Front Slick and Dunlop 155/60/17 KR-108 Rear Slick. (*NOTE You'll still need to keep your weight foreward, to avoid chatter and tucking, but it won't be as bad)
