sold

 

When were these originally purchased? I'm interested in the 255s for fronts, but cant fit the rears (12" rim). If you find someone who only wants the 295's maybe it can work? I am in zip 32615 -- price shipped?...will be buying a new front set after 1/19 regardless but GLWS!

 

the 295 has a section width just under 12” when mounted on a **10.5 inch** wheel. I think they will probably work on a 12, at least as good as whatever you’re hoping to pair with the front yok.

 

I currently have a 305 Falken on the rear 12" and it looks stretched and the car balance is not good with a 265 in the front (way too much oversteer). I am set on putting a 315 Falken on the rear instead of stepping down...

I also think my installer would hate me even more if I asked him to mount a 295. He did not enjoy the 305

 

SS was won this year by a GT3 with 295/35-19 on a 19x12 wheel…

 

Do you know what size was on the fronts?

I assume they only ran a 295 because it was a A052 and that's as large as they go, and wanted the faster tire for 3 runs in Lincoln? I want something that can take a bit more abuse/deal with heat in the rear better (for the amount of events I do, which include some light TT and co-driving, all in the hot South), so I am set on the RT660 for the rear for now. If I am not happy midyear perhaps, I'll give the golden setup a try

 

255

 

Yes we ran the 255/295 setup for Lincoln because of the Yoko and its what is available. I however do run the Falken often locally with a 275/315 setup on the GT3. So I would recommend this as a setup for light TT and it is still amazing for autox. I won two years ago in Toledo at the pro with the Falken setup.

 

I thought SCCA SS was +20mm max which comes out to 265/325 for the 991 GT3.

 

Restrictions are on the wheel width, not the tire itself, at least for street classes.

 

Never been any such restriction, at least not in over a decade.
Rim offset allowance in Street classes is +/- 7mm from stock plus a +/-1" diameter allowance.
Some classes, such as Street Touring, have a max tire width restriction, depending on various factors like 2WD vs 4WD, etc.

 

Thanks for the clarification.

 

I'm about to order the tires so I think I'll go Falken 275/315. What pressures do you run? I'm getting 5 mm extra offset on the front 19'' rim I'm getting, I hope it won't rub in 275. I can downsize to 265 too.

edit: stock front is 20x9 ET55, I'm getting 19x9 ET50

 

FWIW, when I ran a 305/265, it was almost impossible to induce understeer. I am dropping the front down to a 255 (and increasing rear to 315) and will know in a month or so if that worked.

 

On a 991 GT3? I ran stock rear, oversized (+20) front 71R on a 997, no problem. But the 991 turns in a lot easier and has way more power. Can you not dial in some understeer via tire pressures or the sway bars?
