245's on both my fronts and rears!?!?
I was just checking the size of my tires to begin the process of pricing a new set.. and when I look... I get very confused. I have always been told that the rear wheels are wider than the fronts and therefore I couldn't rotate my tires.. I have an 03' Touring.
Well I never looked before (original tires that came from the dealership) but I now see that they are 245/45RZ's on both front and rear... I always thought that the rears were 225?
Ummm what's going on here?
I never bothered rotating knowing what I 'thought' was that the tires were different sizes...
I mean... would a 245 tire fit on a normal front wheel? I honestly don't know alot about wheels/tires.

I, too, was wondering the same thing about rotating tires. Consensus seems to think it is ok. But I was a little skeptical at first as to whether or not the "non-stagger", "same size all around" set-up would affect the TCS/ABS, as I heard it may affect VDC, but if your tires are "factory-direct" and 245-45-18 all around, I am DEFINITELY convinced that you will have no problems rotating them!

So, I don't know if I have all the facts correct or what, but were the tires from your '03 Touring "factory," or "aftermarket" that somebody else just put on over the stock 18'' wheels? If they are indeed factory, I don't understand why some members here have argued against the "same size tire all around" concept. I mean if it comes factory that way, there is no way there should be any problems w/VDC, TCS, ABS, right? Unless Overall Tire/Wheel diameter (height) is the problem being considered.
Maybe those members have done some other kinds of mods to their vehicles leading them to believe their issues were due to the "rotating" tire set-up, but in reality not actually the case? Still unclear about this. Anybody with stock Touring Z's, please shed some light!

Anyways, now thinking my set-up of 265/40/18 all around should be fine. Hopefully I don't run into any issues w/install, besides maybe some fender rolling.

I'm running 265's all the way around. No rubbing at all. Running a staggered setup causes under steer and its much better to run the same size all the way around for handling and then you can rotate your tires. If you have a drag only car then a staggered setup with a small tire makes sense but this is at the expense of handling.
Also you get quicker steering response and better consistancy of traction loss with a stretched tire. It baffles me why so many people use 305's or larger on G35's and 350's at near stock hp. And then run a smaller wheel/tire up front. This kills handling and what is the reason for having that big of a tire. Also running a streched tire or proper fitting tire you will have a larger contact patch then you will by running a bulging tire. Unless you are making over 400hp to the wheels a 235 or 245 will have plenty of traction. Running a 265 is a perfect compromise. Wide enough to have great traction without the over kill of huge tires. Especially when you look at the weight a large tire adds. Reducing the rotating weight makes a huge difference. If you have a crazy built turbo charged car and need that traction I apploud you but for most of us that is just not needed.

I run 225f and 235r on the daily driven tires, and I have some 255/40's all around on the Volks for the track. All 17's.

But thanks for the info, though. I think it really helps us all understand how the Z thinks/works just that much more! I think this is a great thread, btw.
