Same size tires and rims on the four corners
I just bought a 2008 Grand Touring Roadster with the Brembo brakes. The wheels are scuffed up from scrubbing curbs and I was looking to replace them. My thought was to go to the same size front and rear so I can rotate tires. Has anyone done this? What size did you settle on? I am not looking at increasing the 18" diameter.

Don't mind that other guy he's not very nice. Probably some ego issues.
But anyways, yeah you can run a "squared" set up.
Run a search of this site through google and you'll get some good threads with tire and rim sizes that'll help you out.
New ride huh? Lets see some pics!

Thanks PP08HR,
I had searched but did not have the word "Squared", makes sense, just never heard it before. My car is black and it has been raining here for some time. It is in dire need of a bath before I can get pics.

If only there was a section where it was label "wheels and tires" where people go to discus this question. If only there was a sticky that had all this information covered already....

Yes, many people run a squared setup. Take a look in the Wheels/Tires section.

Neilca congrats on your new car! Ignore the smartasses, there's quite a few on this site. That being said a search will give you the details to your questions. Enjoy that Car.

Yeah a search will let you know not to do that because your going to have problems with your traction control...
Default Also.. Q: What size tires should I buy?
Q: The "Slip" light come on randomly, especially in turns, even though my tires aren't slipping. What's up with that?
A: Both the Traction Control System (TCS) and Vehicle Dynamic Control (VDC) can cause the "slip" light to come on. There are a couple of things that can make it come on even though you don't feel/hear your tires slipping.
The most common cause for this behavior is replacement of the OEM tires with a different size. All Zs come with staggered tires, that is to say the fronts are a little shorter than the rears. This causes the tires to rotate at different rates which TCS and VDC depends on for normal operation. If you install tire combinations that don't maintain that stagger, it can cause problems for TCS/VDC resulting in the "slip" light illuminating.
The stock tire sizes and Outside Diameters are:
225/50/17 25.9"
235/50/17 26.3" (0.4" stagger)
225/45/18 25.9"
245/45/18 26.7" (0.8" stagger)
245/40/18 25.7"
265/35/19 26.3" (0.6" stagger)
265/40/18 26.3"
285/35/19 26.9" (0.6" stagger)
When choosing new tires, try to find front/rear pairs that maintain the stagger of at least ˝" and less than 1". You should also look for front/rear setups that maintain the same OD as that will keep your speedometer and odometer accurate.
Here are the most common "upsized" tire combinations. These are known to work and keep TCS/VDC happy.
245/40/18 25.7"
275/40/18 26.6" (0.9" stagger)
245/35/19 25.8"
275/35/19 26.6" (0.8" stagger)
255/35/19 26"
285/35/19 26.9" (0.9" stagger)
245/30/20 25.8"
275/30/20 26.5" (0.7" stagger)
Check the manufacturer's website to find the Outside Diameter of tires before you buy them, or use one of the online tire calculators:

A less common cause for the "slip" light to illuminate comes from replacing the fronts or rears only. If you replace only the fronts or rears, the stagger may not be what you think it is because the other worn pair is actually up to ˝" smaller than they were when new.
New tires also come with a release agent on the surface of the rubber that must be worn off. That makes them slick and can result in your tires actually slipping, hence the "slip" light.
NOTE: The slip light does and will come on during "normal" driving that is unrelated to tire size or wear. If you apply too much throttle when launching or going around a turn, the wheels will slip and cause the light to illuminate. Also, driving on slick road surfaces (water, oil, rocks) can also cause your tires to slip.

I bought the same size rims but chickened out on changing the tire size. I am going to see how these wear without rotation.
Wallygator,
I assume you had no issue with the traction control by going to 245's. Thanks for the input. I may do this if I do not like the tire wear.
