On 18" wheels a 315/30/18 is plenty rear tire for a GT3. Same on 19"... A 305/30/19 is plenty. Do not think more tire will make up for less talent.

. Man, I'll have to do some googling.. I know the RS has a wider track but sI'm almost certain that the 7.2GT3 has a different (the 4-wheel drive) body than the 6GT3. And I have not had any beer yet
But anyway, narrow. more wide or (really) wide body
, I'm still on the hunt for an answer of whether or not the RS-sized tires for F and R fit onto the GT3, stock wheel or RS wheel or any other wheel. I wouldn't want to have 245's or even 265's in the front and not at least 325's on the rear. PS: 345's can't be that tough to put on an RS, CarreraGT has them (Hoosiers) and they seem to fit -and he's really fast! Ask me how I know

He is probably busy on the Fiat forums comparing valet spots they gotover the weekend

And they're only $200 more!the same size in front and going bigger in the rear could make you go slower in theory. You will have to have a different alignment for sure as the rear will not rotate like it does on 305's. I've seen guys show up at the track with Hoosiers and still have the same time at the track. A lot if it is talent not tires.
Also 997.1 and .2 GT3 and Carrera are narrow body. RS, Turbo, GTS and Carrera 4 are wide body cars.

My Sport Cups (10 GT3)...3400 miles, 3 or 4 autocrosses.(but used Hoosier A6 for like 15 serious autocrosses)....
Rears just about gone...even wear no cords, but I don't know if it would be safe to run them on the street until cords...front have like 30% left.
I think I am going to replace my Sport Cups...with......Sport Cups...identical OEM tires and sizes.
IMHO....don't go bigger with cups use stock sizes.

OK, I'll weigh in. The wide body vs. narrow body version of the cars has been widely discussed and reviewed. If you choose to disagree with some very knowledgeable people here on the forum, its your prerogative, I guess. I think everyone here is just trying to help. I will say that the most of the guys that have posted in this thread (myself excluded) are pretty accurate and have helped me out tremendously.
On the subject of tires, I will echo everyone's comments on the MPSC's. I have run the Corsa's, R888's and Sport Cups and have a set of the Michelin Super Sports for street use. If you're going to run DE's, forget mileage. Tracks shred tires. That's the trade off.
So far, I have 6 track days on my MPSC's and am just getting down to the wear bars. I'm going to run them until they cord and when they do, I will buy another set. My experience says that they provide the best grip and longevity of the tires that I have tried on the track. If you've got the time, sometimes you can find used sets on the web. There are lots of P-car people that don't track our cars and often sell these tires very early for a longer lasting "quieter" tire.
Good luck and I'll be interested to hear your experience on finding the right tire setup for your car.

Ask me how I know But 997.1 GT3 and 997.2 GT3 continue to have narrow 2wd platform body.
The 997.1 RS and 997.2 RS have the 4wd bodies .
The 997.1 and 997.2 narrow body has a different rear offset wheel then the RS.
Because of the narrow body and rear wheel offset you are limited to tire size on the rear.
Next time you see a RS park along side and you will see the difference in rear width.
345 MPSC on the the rear of a RS requires removal of rear spacers and tuck n roll of rear fender.

FWIW I ran a set of Pirelli Corsas on my 10 GT3, got 10k miles, 6 track days and lots of spirited driving. They have great grip and can run in the wet. I'll miss those tires as they don't fit on the RS.

As I recollect *all* the GT3s have been based on the Carerra 4 chassis because those were stiffer than the 2's; nly the 997 RSes were based on the 'widebody' 4S bodies (the 996 RS being a narrow body also).
The difference between the GT3 (997.2) and the RS (apart from the wider track of the latter) are the wheels/offsets:
The GT3 wears:
- 8.5" x 19" ET53
- 12" x 19" ET63
The RS:
- 9" x 19" ET47
- 12" x 19" ET48 You can easily fit a 9" up front, I have the HREs. A 245 up front should be possible, and maybe even a 325 in the rear although it may be tight.
I personally like the Pirelli Corsas on my 3.

It's late and I'm going to stop arguing with you
Whatever you call it -wide or narrow- but per the Porsche website, the 2011 GT3's wheelbase is 92.70", the GTS's wheelbase is 92.52. 
Small difference but ... 
.
PS: And I will spend my money on the fattest tires I can find so my personal coach can stop complaining about my skinny wheels

Wheels base is NOT what determines a wide body and narrow body 997 car. It's width...rear width to be exact that determines a narrow body to a wide body and it's only the rear body width that is different.
GT3RS, Turbo, GTS, Carrera 4 and Carrera 4 S and Targa are WIDE BODY based 997 cars. GT3, Carrera, Carrera S are narrow body cars.
The .2" wheel base (NOT rear width..i.e wide body) difference between the Turbo, Carrera 4, Carrera, GTS with the GT3 based cars is due to the lower control arms provide a little more caster.

FWIW, I think there's a bit of a language and written word issue here, but certainly no disrespect intended -- I know that what's Horstair has written is meant in jest even though I can see it reads as being a little sharp.

Now you are
Hey, I told you in my last post that I don't care about what you call "my body". All I wanted to find out what size tires fit onto the GTR3...Did you even read my initial post with the questions I had?
Anyway, I learned what I needed to know about tires for the 7.2 GT3 from the more knowledgable folks on this board. Tx izzone and tcsracing1! Let's move on
