You should have room to fit a 245 width tire up front. Heck, when I ran my 17x9 03' Cobra reps I had a 255/40 Nitto tire up front with minimal rubbing up front. Only time it rubbed was in reverse and steering wheel at full turn. You need to look in to a tires section width and tread width when deciding on size. My BFG Sport Comp 2's run wider than others. So basically my BFG 235 tire up front is nearly as wide as a Nitto 245 tire. I would jack your car up in the front with the jack under the control arm to compress the
suspension while lifting the car up and look at the rim/tire clearance in relation to the strut.
What size tire do you have on rear wheels?
