Is anyone running 305/30ZR19's R888 on their GT3 (NB). The Toyo website says they are good for 10.5-11.0-11.5 rim width. The GT3 has a 12" rim. Your feedback would be appreciated. I know there are lots of threads on tires, but could not find one on this.
Thanks!

You can run 305 tire on a 12" no problem.

I've been running 305/35/18 RA1's on my 12x18 CCW C14s for a while without issues.

I've been running the "Official Rennlist's Most Hated Tire"...Toyo R888 for years.

I currently run a 305/30/19 on 12" wide tires no issues at all. Most all tire manufactures...Michelin for example...show specs of only 11.5" wide wheels for 305/30/19 tires but Porsche ships GT3's with a 12" wide wheel and this tire size.

I run them on mine. No problems here either!

Toyo R888 suck, i'd rather lap Sebring in Deputy Dog's goped

Thanks for the feedback. There are not a lot of options for 19" R-Comps out there.

Yes, I hear they suck, but not much for options. With the 380mm disks in the front its a tight fit on 18" rims.....

CCW's to the rescue....

any good forged 19" wheel will fit over 380 mm disk

I have GMG they fit perfect

If stuck with 19" run corsa system.

or buy tire trailer, run cheap street tires and hoothers at track

mdrums

you run 18" wheels...not 19"...LOL

I went with 19" wheels only because I drive to the track (no where to store a tow vehicle and trailer..or even a small tire trailer to tow behind the car) and with 18" wheels you have Hoosier which you can't drive on the street or Toyo R888. With 19" I have a few more choices with Michelin and Pirelli.

Right now I'm on the dread R888's because with my new car I have a good comparison because I know this tire. Next I'm going to try out either Michelin Sport Cups or something from Pirelli.

Mike, R888 back to back with the Michelins will be a fantastic comparo to have for all 19" track wheel owners!!

mdrums

Yep that is what I'm thinking. 1st I need to get in some solid Sebring track days...LOL

See you next week in Daytona for Saturday Sunday. Then off to Sebring in November for a couple of events.

it is actually an interestinng topic - i was told by several people and my shop that for 12" wide 18" rims actual 'right' size in R888 lineup is a 305 tire and not 315 tire as one would assume. 315 sidewalls are not optimal for 12" rim but 305 fits just right. go figure.

in 19" i do not know, so, sorry to OP .
