Default Tire options for ST?

What is the popular tire & size for a GC running in ST? I wanted to get the Dunlop star specs or the Hankook RS-2's but neither are available in the size I was looking for (225/45/16). I would rather run 16" wheels if possible but I can't find any information on other good ST options. Thanks

I'll be using 16x7.5 wheels BTW.

the rs2's should not be an option if you want to be competitive. take a look at the kumho xs instead.

noone makes a good st option in 225/45/16 so the next best size would be 225/50/16 if you're set on running 16" wheels.

So what is the competitive tire size in ST? I'm not a national kinda guy so I'm not worried about that and I won't buy a $200+ Advan tire. I really liked the Star specs on my STi.

It doesn't matter. You will probably lose to a 1989 civic si.

I was running the RT-615's and just bought a set of the star specs to replace em. 225/45/17 on 04 sti wheels.

QFT!

Did you see a big difference going to the star specs from the rt-615's? I only ask because i am considering a switch.

Won't get to try them out for 1-2 weeks. I'll post up my findings after the next event.

I looked locally for that exact car before I picked up my RS. I've never auto-x'd a FWD car but I thought I would give it a shot. Oh well, my RS only cost me 2K. And now I'm spending twice that in upgraded parts.
I decided against the 16x7.5's I was going to get and now looking to see if it's possible to fit a 17x7.5 wheel under there. Anybody know if that works without rolling fenders or does it have to be 17x7? Can I just run more neg camber?

With the negative camber and spring rates you should be running , you'll probably only rub "slightly" in the rear if at all. I have 225/50/16 on the stock RS wheels and with basically 0 camber it rubbed in the back, but not in the front. A quick fender roll later and it's fine now.

If you're going 17, definitely go for the 7.5 inch wide wheel, and light weight if you can. 225/45/17 in your flavor of choice (star specs, xs, re01-r).

I've been trying to confirm if the 17x7.5 wheels will rub with the 225/45's. So you don't think it will?

I know Rota has a 17x7.5 that is made for WRX wagons. Its slightly more than their normal et48 offset should clear GC fenders. Either way offset will be critical, as will the camber selection.

it all depends on your ride height and rear neg camber. i rub right now with 17x7.5 rota's and 215/45/17 kumho xs, springs are p1's and it has about -.8 for camber.

your best bet to make sure the 225's will fit is to roll the rear fenders

i've run the starspecs in 225/45/17 on 7.5" sti bbs's (+53et). fits fine up front... and ok in the rear with -1' camber, coilovers and a fender roll.

615's, ad07's and ad08's also fit fine with the rear rolled (225/45/17)

this photo has the dunlops mounted up, and they're the widest 225's I've seen to date

Best 16" tires for you might be the 225/45/16 Toyo R1R. Hankook may come out with that size later in the RS-3 which is supposed to be much better than the RS-2. I used to run 215/45/16 Azenis rt-215s on my GC8 and liked that size for tight courses and the new Kumho XS is available in that size and is a top performer.

As mentioned above the hankook RS-2's are not good, they get greasy FAST.

I was running RE-01's when I got some on sale.
I would look at
1. Dunlop Star Specs
2. Yokohama AD08 - which have amazing grip in the wet also, in case that's a factor
3. RE-11
4. Kumho XS

I know the first two are great tires, don't know much about the last two.
