Simple question, I've read around quite a bit and I'd like to go with a 245/40/19 - 275/35/19 setup when I replace my tires. Everyone I see doing this does not have AWD. Can I run a 245/40/19 - 275/35/19 setup on a G37xs without hurting anything?

 

All wheel drive requires front and rear tires to be of a diameter that is within 1%. Use the tire calculators that have been stickied on the forums here to determine.

 

Best staggered size for AWD would be 245/40/19&285/35/19 or
235/40/19&275/35/19 the difference front to back is minimal w/ both those combos.

 

Thanks for the replies guys, time to start checking out tires.

 

My understanding is that a staggered setup provides a traction advantage in a RWD car without limiting steering response. The drawback is that you can no longer rotate your tires, especially if they're directional. What would the advantage be in a AWD car where traction isn't ever a problem?

 

Most that get the staggered setup are doing it for a more aggressive look and a bit more planted feel in the rear, not a lot of performance advantage, having a bit more rubber in front may give you a bit better launch but I'm guessing that would be about it.

 

Yup and the fact that our X is not full time AWD and mostly rear means alittle more in the *** aint a bad thang !

 

Essentially what he said. If I'm already buying tires and I can improve the look of my vehicle a bit then I'm down for that.
