gt2 size tires are 18"s..the best sizes are 235/40 X 315/30 ( oem gt2 ) so maybe the question should be: is it worth it to run 19's!? lol...18's really are optimal for handling and yes, you can run a 315/30 on a stock twist. whether or not you have any liner rub will probably be driving condition dependent. if you are lowered, on 19's you'll rub at hard lock, at the least ( i did anyway..)
but most opt for the 315/30 with the fenders rolled. using a 15 spacer just pushes it out that much more, and its a wicked oem look on stock twists. especially if "lowered". on the plus side it will ride better. not as "harsh" as 19's can be. rolling the fenders is not a big deal and isn't as bad as it "sounds" depending upon the kind HAMMER you use lol

If you already have nice HREs I would just stick with those. We have pretty smooth roads here so 19's are fine. Order up some Sportcontact 6 or get some PSS in 295 or 305 if you want sidewall.

If you look around for 18's they are getting scarce as well. PS2 production is spotty, Rivals in 315 can be hard to get as well. Yokohama discontinued the 295 AD08. The easiest to get tire with the most plentiful options is the 305 in 19 inch, the same size as the 997 turbo and gt3.

The 245 fronts are a closer match for either option. If you go 305 you can get some really sticky tires like the Bridgestone re71 or the Yoko AD08. The Michelins are probably the best all around compromise though.

19's are good, you just need to find the right tire combination. I spent way too much time researching this and explored every option.
If you go with 18's:
Stock 225/40/18 or 235/40/18 fronts along with the 295/30/18 PS2 are best in this size.
GT2 sizes 245/40/18 front with 315/30/18 in PS2 or BFG Rival tires are best.
If you go 19's:
Best fit but hard to get 235/35/19 with 315/25/19 Sportcontact 6 ordered in from Germany are best in this size but low profile sidewalls have rougher ride and less grip. Toyo and Nitto make these but are poor tires.
Next best fit 245/35/19 with 295/30/19 Fronts are .2 inch smaller than rears so front drive may have less efficacy but these are available in many great brands and are very close in size. Won't fit on 12 inch rims though.
Next is 245/35/19 with 305/30/19 Rears are .5 inch taller than fronts which is pushing it, but I haven't heard of anyone ruining their diff with this setup. Lots of rubber on the road and plentiful tire choices. I like the Michelin PSS or new 4S for street tires and the Brigestone RE-71 or Yokohama AD08 are great sticky aggressive tires with awesome sidewalls that will work on track.
