@SpicyPaneer @heavyD Have you actually experienced summer tires turning really slippery in 40-50° F? Which tires exactly? I've never experienced that, and I've driven with summer tires in such weather for many years. All the ones I've used grip perfectly fine at those temps, still easily better than a typical allseason. I'm sure summers aren't at their
very best in such temps, but they don't turn into hockey pucks!
If you feel my summer tires are unsafe at 40-50° F, then you're saying a tire like the Primacy MXM4 (that often comes on base model Tesla's) is unsafe at
any temperature. Which, okay, I might agree with that!
Even my old 200 TW street/track summers that I used back when I did track days, did not turn into hockey pucks at those temps, though I did not run them year round.
