I have a 2004 G35 Coupe in need of new tires. I really want to try out the Michelin PS2s, but I'm unclear on tire sizing.

My current tires are front: 225/50/17 and back: 235/50/17.
The tires I want are front: 225/45/17 and back: 245/45/17.

So, first question, will these fit?
Second question, will it adversely affect traction control or anything else?

Many Thanks!

you should be fine but why not run the 225/50/17 upfront? is that size not available in michelins?

 

235/50/17 pretty much the same as 245/45/17???

im wondering the same thing, there's a great deal on TIRERACK.com
