Thinking of pulling the trigger on 19 inch wheels(for street)with the following tyre sizes 235/ 35/ 19 and 315/25/19.

I have 17mm rear and 5mm front spacers.

Feedback from anyone who has fitted those sizes before would be appreciated.

 

if you are getting aftermarket wheels then you should be able to find appropriate offsets and not have to use 17mm spacers.
unless you got an incredible deal on narrow body wheels, then you should find wheels with the appropriate offsets.
the tires sound right, is the rear 11 or 11.5, 12?
