don't want staggered tires
 

Have a 2012 g37s coupe. Was wondering if I can run 245/40/19's on the front and back and loose the stagger, I'd like to be able to rotate tires. I have the stock wheels. Thanks.

No. The wheels are wider in back than up front. To do what you want, you need to have all 4 wheels the same size. You can trade or buy a pair to get a set of 4 same sized wheels. Then you can do it.

You can use the same size tires.and have a shop flip the tires themselves around from front to back side to side.where i live.its 20 a tire mounted and balanced.pretty cheap.so 80 plus a tip to rotate tires off the rims not just entire rim and tire...i run camber and get camber wear.so i flip my tires inside out.to prolong my cambered tires.Goodluck

The front wheels are 19x8.5 and rears 19x9's. A 245/40-19 will fit wheels 8" - 9.5" wide so you'll be fine, but cant rotate due to the stagg wheel sizes. That's a pretty common tires size upgrade.

I did the whole rotating single sized tires on staggered fitment wheels thing before. I had 350Z wheels on my old Maxima. It is a pain in the a** and will cost you about $100 each time you rotate them. If you rotate them every 5-7K miles, you could just buy 2 sets of rears for every set of fronts you wear out and still come out ahead. Not to mention that the tire shop WILL scratch up your wheels at some point with all the additional mounting/dismounting every time they rotate.

So I guess I should change my statement - you CAN actually do it. But you SHOULDN'T. It will cost you more time, effort, and money than just running staggered and buying more rear tires than fronts.

I guess if you have assymetric tires (the ones w/ OUTSIDE stamped on them) you could at least rotate side to side without having to do a remove/remount. Better than nothing at least :)
