    Anyone using CUP2s in winter?

    As per title. I've heard that the CUP2 tyres can be dicey in the wet, is anyone using theirs through winter?

    I drove my GT3 from Portland to Bend in late spring with Cup 2’s, in the 30’s with snow on the side of the roads and wet conditions. No drama but I was careful. The main thing is the tires can’t maintain pressure in the cold weather and pressures drop. A recent trip in our 18 Turbo with 4S’s over Shasta in the 20’s, rear tires lost 4 psi below cold pressure settings, again I was careful. TPMS is a great tool.
