- 2017 White Orchid Pearl Civic Si Sedan
I've been googling the difference between summer and all season since Honda seems to be shipping only SI's with summer tires here to Indianapolis, where we get actual winter. Anyway- summer tires have no problem with rain, its cold and then snow that does them in. They loose their flex as temps drop and thus loose their grip.
"As ambient temperatures get colder, typically in the 40-45° Fahrenheit range, summer performance tires lose a noticeable percentage of traction as their tread compound rubber properties change from a pliable elastic to inflexible plastic. The tire industry uses the term "glass transition" to describe the temperature where a summer performance tire's grip/slip performance changes dramatically. "
