I found an interesting post in the Autocross forum by chriswd62 that I am cross-posting here since it indicates the possible release dates in March and August for new sizes of the RE-71R from Bridgestone:

So, no 305 or larger in 20" appears to be on the horizon for this tire in the next 8 months at a minimum, but it appears that GT4 sizes will be available by August. If you have 19" rims for the GT3, you will be able to fit them with a 305 rear by August, to go with a 245/255/265 front, depending on the final diameter of the 305 and your setup preference. Here is a screenshot of what Bridgestone shows on their website as sizes that are already available:

I know it would be nice to have more tire options (I just ordered a new set of Cup 2 for $1,500) but why would any other tire company bother to manufacture an N0 20inch tire considering most people will just stick with Michelin Cups. I reckon at most only 1-200 hundred GT3 owners globally that would genuinely consider buying an alternate tire. That's a small ROI by anyone's standards.

 

Are replacement Cup 2s really only $1500 in Belgium? I wish we could get them that cheap.

These alternate tires will not be N-rated, and will fit far more cars than just GT3s. The MPSC2 is a fine tire, as I said in the OP, but I believe (and hope) there are far more than 1-200 GT3 owners world-wide who will track their cars and want a good high performance tire at less cost. The only alternative right now is the Trofeo R or Dunlop Sport Maxx Race, both of which are just as expensive, and don't perform any better. If you only buy one set of tires every year or two, you probably don't care. If you're going through tires every 4-6 track days, it would be nice to cut your consumable costs by $800/set or so.

 

Yes, you can buy them over here at a pretty good price. I got a set for 1,394 euro = $1,576 USD. Even though I don't need them right now, I thought I would get them and store them away until summer.

 

That's a really good price! I guess your proximity to France and the exchange rate is helping you out. Our price is nearly $2,000USD here shipped from Tire Rack without tax! The best price I have found on the Trofeo R is $2350USD. The Dunlops are just as much and not that desirable to me from what I've heard about them.

Cool! Finally a decent reason to get a set of 19" wheels if these tires work out well.

 

Cup2s have another few days in them so I'm ordering the RE-71Rs for the March 4-5th track days at Buttonwillow.

 

Wow.....I don't believe it...I have finally found something associated with Porsche which is cheaper in Europe than the US, the home of cheap everything compared to the ROW.

 

Not everything is cheaper here. When I found out that the Base price on the 991 GT3RS in Canada is $200,700 Canadian, or about $147K USD, I started thinking about moving to Vancouver.

You may want to reconsider when you find out how much tax you will have to pay on it and how a house costs in Vancouver...

 

I'm probably going to run the 255/35/19s and 305/30/19s in the fall.

 

I called TireRack and ordered 20 in. RE-71Rs for my GT4!! Supposed to ship 8/1/16. Thanks to all for getting us these sizes!

 

What site is this if I may ask?

 

I just called Tire Rack and the guy I talked to says they aren't expecting any RE-71R tires in 20" yet and couldn't find anything in his search on their system to indicate anything incoming. Who did you talk to when you placed your order? Damon?

Thx,
