Why don’t summer tires work in the cold? Does their effectiveness decrease with temperature in a linear or step like way?
In: Physics
The rubber has a mix that is meant to be working at a certain temperature range. Above and below, it won’t work the same way.
In your scenario, below recommended summer temperatures, it loses flexibility and so it doesn’t react properly at road asperities and generally has less grip (not being able to flex and enlarge the touch surface with the ground)
