The tires are 215/35r17. The wheel manf. drilled the rims for us. honestly dont know the offset. they said they would take care of it... they retail for 2499 installed. i know its why high for 17's but they said it was cause of custom work. i takes about 2 weeks a set to get them in..
this is the only close pic i have. i will try and get a close up later
as for driving: turning is the same. Road noise a little higher. It does stiffen the ride a bit; how ever that is to be expected with any tire with a short side wall. Its fun to drive though, handles GREAT and looks sweet. The pics dont do it justice
