From factory, for an Xs, the fronts are 225x45x19 and the rears are 245x40x19 correct?

Well with the OEM wheels, my tires are the same front and rear (225x45x19)

Is that an issue? I'm assuming I just have less grip and maybe stretch in the rear?

 

Your tire sizes are correct (all four are 225/45/19) since you have the AWD S coupe. Only the RWD Sport models come w/ staggered (wider rear wheels/tires) setups.

 

Okay, thanks! Glad that was cleared up. I don't have an owners manual and I thought wrong.

 

Yeah, looking good there!
