Re: Wheel Size Calculator / Rim Weights
I replaced my 235/50VR-17's in the rear on my coupe with 255/45ZR-17's. I have had no problems. My speedometer should still be correct, right?

Re: Wheel Size Calculator / Rim Weights
Go to www.tirerack.com. Choose your tire. Click the "Specs" tab and it will list permissible rim widths for your tire. Tires vary by manufacturer. You can put the front Pilots on a 8.5" rim for instance, and the rears on a 9". Every tire has a range. I used this to determine that I can go with an 8.5 in the front and a 9 in the rear and keep my stock tires.
If you want to replace your tires with wider tires, make sure you pay attention to weight. The pilots are among the lightest, the Bridgestone Pole Positions among the heaviest. You will notice. You will also notice performance variances depending on what you do to your tire widths, so make sure you define your mission first.
Do you want to drag? Drift? Corner? Looks only? Contact patch alterations will cause differences in performance.

The second link is for rim weights, either factory equipment or aftermarket wheels. I don't know how accurate this site is, but should give you a pretty good idea of rim weights out there.

tires sizes
Hi,
1st post!!!
I own a 2003 g35 coupe, purchased nov 2002.
I replaced my goodyears with Michelin pilot sports.
Stock 17 in rims:
Front 245/40 r17 (7.5in wide rims)
Rear 255/40 r17 ( 8in wide rims)
almost 2 years and no problems, ever.
great tires too, by the way, great traction
i'm actually lookin into putting 275's on the back. yes,yes I know everyone might think they wont fit.... but.... a freind who also auto-crosses his 350z has 275's, are you ready for this..... all the way around!!! no problems yet in 2 seasons of soloII.
the recommendations the manafacturers give are alittle on the safe side, for there protection and ours. But they can be stretched alittle...
hope this helps

Selecting tire width is generally pretty straight forward if you know your rim sizes. I would not recommend 275's on an 8" rim, that is just a bit too much rubber for that width wheel. Sure some people do it, I also see guys wearing white socks with sandals, but you will never see me doing it I can tell you that much =)
For more details on selecting tire widths, here is an example I posted in this thread that shows the simple math used to figure out the best width tires for 18x8 wheels:

203/235 = 86%
203/245 = 83%
203/255 = 80%
203/265 = 77%
203/275 = 74%
So it looks to me like the 255's are probably the best fitting tire, with the 245's and the 265's being safe alternatives.
