Looking for some ideas on what air pressure to run with Potenza RE11 at an autocross. Running stock C6 ZO6 sizes with DRM shocks and Hotchkis sway bars.

I ran 36 frt 32 rear on my 08 Z51 with stock size RE-11. I now have a 12 GS but have been unable to locate RE-11 in GS sizes. Where did you locate stock C6 Z06/GS sizes?

I'm a Bridgestone Tire dealer and ordered them direct. They are listed on there website. Not sure how much longer they will be made since they just released a new RE-11A in limited sizes.

Thanks for the RE 11 info. I was at Barrett Jackson in West Palm Beach last month and spoke with a Bridgestone rep, he said that GS sizes were in the works and probably available from Tire Rack first. I will keep monitoring Tire Racks web site. Or should I look for them at my local Firestone store?

I would check locally.

TireRack does not yet list them available. Is there an ETA?

EDIT: http://www.bridgestonetire.com/tire/...e-11?advisor=t
Bridgestone lists the tires on the site, but Tire Rack does not.

^^ I second that

While searching for more info on available sizes of the RE-11 I came across reviews for the new RE-11A, I wonder if this is the tire that will (someday?) be available in GS/Z06 sizes. Does the A denote autocross? So far I have searched Tire Rack, Tirebuyer.com, carid and Firestone stores' web sites. None of these show the GS sizes.

"Sharing the tread design of the popular Potenza RE-11, the Potenza RE-11A adds an exclusive tread compound that combines silica with a new long-link carbon black to increase road contact and abrasion resistance while promoting tread rubber flexibility across a range of cool to hot temperatures."

As far as I understand, it wears better and lasts longer, but does it have more traction than the regular RE-11? By the way, in a recent comparison by Car & Driver, RE-11 was compared with some of the leading extreme performance and Mac performance tires, and Michelin's Pilot Super Sport tires made better lap times both in the dry and when wet compared to RE-11s...

I see that the tread wear rating on the Pilot SS has increased to 300. I recall the last set of PS 2's I owned that the tread wear was 220. I don't think one can rely on those numbers anymore (if ever) to give you a sense of how soft tread is. The RE-11s I had a year ago on a C6 Z51 had a tread wear of 180. I think the new RE 11 is rated a 200. They are getting harder and improving traction at the same time. Interesting.

RE-11s are 180, while RE-11As are 200 treadwear. I never tried RE-11As..

36psi hot worked well on road course.

My car is the narrow body and have been running these in my sizes for 2 years or so. I always check the treadwear indicators on the side. For autocross I usually don't exceed 36 psi. I like running 34 front 32 year - hot. Hope that helps.
