We all know that summer tires have more grip than all season tires in warm weather. But did you know that summer tires outperform all weather tires in the rain? Summer tires are optimized for excellent road grip whether it's baking hot, slightly damp or raining heavily on the road. They're made from a tread compound (the mix of rubber and fillers that make up the tread) containing sticky additives for road grip in wet conditions. But this tread blend also provides enough stiffness so tires hold up and retain their shape when the heat is on. This keeps rolling resistance to a minimum on hot pavement. Tread patterns typically feature shallower, straighter grooves than what you'll see on all-seasons, and solid, continuous ribs, so more rubber is always in contact with the road. The result: more stability during cornering, braking and acceleration. Read this informative Article: https://www.popularmechanics.com/cars/how-to/a7760/know-your-tires-all-season-vs-summer-9647443/
