why would you want a drag radial on the front?
I don't know.
Guess I'm a dumbass when it comes to tires... 
I was trying to keep the tread patterns the same. Should I go with 555s on the front and 555Rs on the rear? If that's the case, the 255/40-17s look nice. Not too wide and about the same sidewall.
that's funny... did you buy your wheels from an e-bay store? I got my 18x9, 18x10 FR500's with tires for just under $1,000 shipped... man that was a great deal even if the tires are chit.
