20" Hoosiers for the GT3
I've only seen this mentioned once as a rumor in OrthoJoe's Track Journal but now it's official as far as I'm concerned - Hoosier will be offering 20" A7 and R7 tires next year.
I say this is official because I got the word directly in response to an email that I sent to a Hoosier product manager. Complete size designations are not yet finalized but he expects that the 20" R7 will be offered in 245, 265, 295, 315, and 345 sizes. He said that he would be able to give me an update next spring.
This is great news to me because I use and like Hoosiers on my GTS but have not been eager to drop to 19" wheels on my GT3. I prefer 20" wheels because I trust the Porsche engineers' philosophy that "bigger is better" when it comes to wheel sizes. They clearly feel that the larger contact patch overcomes the weight penalty.
I know that there are some number of GT3 owners that are running Hoosiers on 19" wheels. Assuming that most of you still have your factory 20" wheels, I would be interested in hearing of your experience if you decide to compare the Hoosiers on both 19" and 20" wheels.

I heard that as well. Apparently the problem was not demand but rather the machine that makes 20" tires. Great news for GT3 owners but not so much for new RS ones. I wonder if changing the RS's rear wheel to 20 would work but not sure if they will have a same size tire with a different rolling diameter, ugh.

Get a tire trailer setup for your car.
An A7 or R7 can hydroplane on a puddle of mouse ****.

If you frequent one track only, most venues will have a shop that would store them for you for a nominal monthly fee. If you go to multiple tracks or track infrequently, you can drive but it really has to be bone dry and a short distance as they are not meant for rain and do wear rather fast.

Just curious - why the need to inflate Hoosiers to high pressures for street driving?

I drove my RSA from Cincinnati to Road Atlanta on Hoosiers once. That was a long tome ago. Wouldn't do it again.

Those tire sizes should work for GT4 also. I think with many shared components among GT3, GT4, and RS it will make offering special parts more attractive to the makers of those parts (much larger market than if each used unique parts). Unfortunately, the 21" wheels on the RS are only shared with the 918, so that could take longer.

Hoosier A7/R7 work really well on wet tarmac buy only to a degree. I ran my A7s wet and dry yesterday. 65 seconds wet and 69 dry. By "wet" I am talking about color change like a slight mist would give you. If you can see the slightest reflection of the sky you will hydroplane like on ice.
Good to hear about the 20s as I was wondering what to do when my GT4 arrives next month.
