Anyone have any intel about Bridgestone making 19” re71rs in sizes wider than 275 for the rears?

I've been emailing them on a regular basis requesting GT4 sizing. I'm not holding my breath

I might have to do 245/40-19 BS re71rs fronts + 295/35-19 Yoko a052 rears…

I would rather use a052s all around, but in their 19 fitments, the front diameter would be 4-5% smaller than the rear. I would also prefer all re71rs, but the 275 width rears...

Yeah, our GT4 sizing seems to be an odd ball combo that not many tire MFG. decide to make.

Maybe by the Lotus Emira using the same sizes as us, it will give a little more push for tire MFG. to decide to product them. I'm REALLY REALLY wanting the RT660's in our sizes.

TireRack shows them in stock in 285/35-19

^^^ Thanks beez. Just ordered the RE71RS in 245/40/19 and 285/35/19. The diameters should match Front & Rear and stock size about as perfectly as you can get.

Cool!

What 19" wheels are you using? I'm using Apex 19" SM10 on my CGTS 4.0, with 255/35 and 295/35 Cup2s. I want to dump the Cup2s and try the Yoko AD09s. I've heard a lot of good things about them. Also thinking about the Bridgestones, but just not convinced they'll hold up to track use.

The RE71s you bought are the perfect size to replace the OEM GT4 20" sizes.

Out of curiosity, why? The RE71Rs were fantastic track tires. What leads you to believe the next gen wouldn’t be?

According to my TR contact larger 19" 71RS will be known in Feb if??? they are coming. Another cleaning lady said ~ April with a grain of salt.

My wheels are custom BC Forged 19" wheels ordered specifically to meet SCCA rules for "stock" class. I wish (and I'm sure a lot of others wish) that Apex would just make 8.5" wide front wheels that were SCCA-legal for the GT4/Spyder, but here we are...

Ah, the "stock" SCCA 8.5" thing. I'm running the 9/10.5.

I've seen so many advanced and instructor group drivers tear them (the previous gen) up on the track in a day or two. Great for AX, but not for track use. I want to try the new ones, but hoping they'll handle heat better and last longer. I'm going to try the AD09s first though. I've been using SC2s - they handle the heat well, are pretty stout, and are reasonable fast, but the 295/35-19 rears that I use just broke the $500 mark, and that's a ridiculous price for one tire, and they're just not that good to command such a price.

I wonder if those drivers are running too high of pressures? RE71R liked lower pressure, like 30-32 hot. Can't run them like Michelins at 34-36.

I just got the new RE71RS and have a track day in a few weeks, but I'm not an instructor level driver. Full set was $1400-something in 19".

CR-S handles heat better than the 71RS but needs heat, be careful on cold mornings. 71RS better cool weather and wet tire. AD09 is more of an endurance tire lasts well but not for setting ultimate lap times with 200 TW.

What are the current go-to tires for stock 20" wheels for AX? I used to like the RE71R but there are no RE71RS in stock size. Currently I am on a set of Cup 2s but our PNW climate is too cold for them except in July/August and maybe September. Some people run Nankang CRS, though they are not 100% stock size. How are the AD09s compared to the A052s? Or the SCR3?
