is no one runnig wide 17 inch on rear or drag radial thanks again if you answer

 

I would suggest 255/50/17 for all 4 corners for the narrow stock wheel, and 275/40/17 drag radials will work for the strip, but I don't suggest driving on them to the track unless its a short trip, and not doing anything stupid along the way. Also filled up to 35 psi while on the way to the track. 13-17 psi on the track.
