front tires...

That's a really tall tire for the front, 4" back space should work ok. But the biggest on the front with out any trouble that I have found is a 205 60 15. Maybe a 215 if the car isn't sitting to low.
On my Cuda I ran a 235 60 14 and it cleared on stock rally rims. But they are probably a good inch lower over the 15" rims.
