Hey Gang, 2014 Q60S AWD (Late 2013 G37 Body Style) currently running 225/45/19 on stock rim sizes. Looking to move to a 255/40/19 and just wondering if I will have any body interference issues or rubbing on the front or rear tires. Car is stock height and not lowered in anyway I plan to use the same sized tires all around and will be running all season tires...Any brand recommendations?

 

Someone more familiar will have to confirm rubbing or not of the 255/40/19. Gut feeling says you'll should be fine in that regard.

Speedo error nearly nil. I'm a fan of michelin pilot sport AS series. Ran AS3+ on a different car, now AS4 on the stinger. It's no PSS but does give nearly year round driveability. Being a cancuck you got dedicated winter tires? If I had to daily drive my car in the winter, I'd be using winter tires here in chicago.
