I have now delved into comparing the two.
I put roughly 18k miles on my PSAS4 tires on a Kia EV6 GT, and my findings were that the tires when new would provide a 60' time on dry pavement of 1.86-1.87 seconds. They would provide a 60' time on wet pavement with standing water visible, of around 2.0 seconds. Their impact on range was negligible, with the car rated at 206mi range (revised for 2024 models to 218), and an actual real world range on these tires, when half worn, of 255mi.
My experience with the CC2's now that the release agent is worn off, is that on dry pavement they will return a 60' time of 1.89-1.91 seconds, and on wet pavement with standing water, 1.97-2.0. I have not yet fully evaluated them yet for range, but I am noticing a preliminary drop compared to the 4/32 used PSAS4's of roughly 5-10%.
The handling characteristics of the tires are that the PSAS4's were somewhat more "direct" in steering feel, and that medium imperfections transmitted further into the vehicle. The CC2's are more relaxed in every way, but still plenty sporting. My car has suspension modes (Normal, Sport, Stiff, basically), and it feels like they all "moved half a mode to the left" with the CC2's. On 40 series rubber, consider me a fan. I prefer this.
Road noise is comparable on most pavement, but when you're doing 70 or above on smooth pavement, I give the edge to the CC2's. In the 20-50mph range, the PSAS4's were a hair quieter. Neither was objectionable.
If all 4 tires got slashed tomorrow and insurance covered it, I'd turn around and buy another set of CC2's.
1) Nothing has ever cut through standing water at speed like CC2's
2) The PSAS4's were way better in ice and snow than anyone had any right to suspect. NO range penalty on my C40 or my EV6 GT.
3) I am extremely impressed with the wet traction of the CC2's. For straight line performance (I have not yet tested braking), they are comparable to the PSAS4's in dry and wet, although their ultimate best 60' times are about 0.04s slower, however, I've yet to test this in warmer weather.
Dry concrete with CC2's, 10/32 tread, 70% SoC, battery optimally conditioned. The 60' is 1.89s:
Dry concrete PSAS4's, 4/32, SoC 97%, battery just under optimally conditioned (this tracks with my experiences of battery % mattering less than battery temp, within reason). The 60' is 1.90s:
This is the CC2 at 90%, not quite optimal conditioning, standing water visible on the blacktop. The 60' is 2.00s:
This is the PSAS4 on the same stretch of road in similar wet conditions, battery at 60%, not conditioned (ambient temps were warmer, though). The 60' is 2.03s:
