Im going with the 5Zigen Fn01RC's in 17x9. Anyway im horrible with tire size to match. What would I get, Im getting Kumhos. Ive heard either 235/45/17 or 245/45/17? Which one would be right??? thanks

 

The 245's and 235's will both fit wheels 7.50 to 9.00" wide. The 245's seem a tad tall and I couldn't verify fitment since its a wheel we don't carry. For the small difference it might be worth staying with your factory size.

 

Are you looking for an R tire or a street tire? If its an R tire the Kumho 255/40/17 V700 VictoRacer is a known good fit on stock wheels.

 

I have 245/45s on my stock tires and they seem to do all right.
