Roadster on page 42 Feb 09

I keep lookin at the A roadster sitting on the salt. I like the look of the radial tires hes running. Anyone got anymore info on the wheel/tire combo on this car? I am getting tired of dealing with white walls and bias ply tires.  

I don't know as that photo was just a grab shot for the races. I'll have to see if I can get the image and zoom in on it to see if I might be able to get the rear tire size but i doubt I'll be able to do the front.
