I have normal summer Mitchelins tyres with pressure and temp sensors in the tyres. When it was zero degrees outside the temp in the tyre after several miles were from memory approx 15 to 17 degrees. that's measures inside the tyre so not sure what the outside surface would be.

So the the theory that winter tyres are better when temps are below 7 degrees!!!

Will check external temp and tyre temp on the way home today.
