I can report that they work well in cold, dry conditions as well. Drove the RX-7 to work the last two days, well, because I felt like it? It's been around freezing at night and low 50's in the day. It squirms a little under power (as much power as a 232K mile 12A makes anyways) when dead cold, but by a mile down the road they gripped nearly as well as hot days. I'm still super impressed with these tires. Passengers always comment about how you can here the tires picking up dirt and all sorts of stuff! They're sticky I explain
