Since it's not a daily any longer and I have a set of "all (3)" seasons on separate wheels, been eying the v730 for the dedicated track set up. I've found local tire shop prices are terrible this year compared to the online warehouses :/

I'm passing through the states in about 2 months and heavily considering picking up a set and driving them across, their prices are making me quite jealous.

Agreed. Tire prices in Canada have been ridiculous forever if the model desired is even available. Last summer I visited a local Bridgestone dealer to inquire about RE71RS. I may as well had been speaking a foreign language. They were clueless.
Now that I’m in Chatham it is an easy hour to multiple Discount Tire locations in Detroit. Eventually I’ll pre-order at DT and roll over there on bald A052’s for a fresh set of ??.
DT is also an installer for TireRack in case DT don’t list my eventual choice.

Anyone had a chance to try the new Nankang CR-S 2023 compound?

Did it change from the existing CR-S?

Yes it did. Andy Hollis at Grassroots Motorsports just posted an article on it (that you need to be a subscriber to read).

Long story short, Nankang changed the compound and internal structure. GRM's testing showed it to be faster and much more consistent than the previous compound. This article has me very close to pulling the trigger on these. If I want 245 I can get them now, or if I want 255 I have to wait until June.

Besides the GRM article, I haven't been able to find any other info.

Decision finally made. Order being placed for 245-40-17. I wanted 255, but those aren't available until June and my current tires probably only have one day left in them.

The specs are interesting, specifically the tread width, when compared to the other tires I was looking at (ECF, V730, RS4). The CRS has a narrower section width while having the widest tread width by a margin.

I tend to overthink things.

Wow! The ECF are much lighter.
I’ll have to look at the weight of the Stones and Yokes.

Feedback from folks other than Andy..

"Drives like the old CR-S but takes more heat to work"

They appear to have less tread width also. Do you want more tread, or less weight for a given size?

My hope is that the effect of that is that they hold on longer before they overheat. GRM's testing showing that they had the ability to stay consistent lap after lap was the part that excited me. Did Non-Andy mention anything about their ability to handle heat?

Yup! They said they were setting PBs 8 laps into a track session. Pretty impressive.

They did say it was hard to place the car at all times and not super confidence inspiring having to drive with a lot of yaw.

Thank you to you and Non-Andy for the extra info!
