Largest Width Rear Tires

[Thieleng]

I am in the process of having the wheels widened at Stockton Wheel to a 12.5" width, I am planning on running the Michelin PS2's or the Hoosier tires, waiting for the wheels before I select the tires. The inner wheel wells on the SPF is being widened (tubbed) by RED in reno, I will be running 335X35 17's on the rear, no modifications for the front. Not much of a selection in tires that size, but I am running the PS2s on my Porsche and like them. Concern with the Hoosier tires on running them on the street, not concerned about wear, just the safety and legality of running a track tire on the street.
