Do you know this phrase by heart? "April showers bring May flowers." Do you live in Florida or the Gulf coast and have the daily afternoon 1/2-hour downpour? Then looking at the rain traction of your tire is very important!
In early June I had the opportunity to drive on four High Performance All-Season tires and critique the wet traction. What I found was surprising!
The four tires tested were the Michelin Pilot Exalto A/S, the Yokohama AVID ENVigor, the Sumitomo HTR A/S PO1, and the Firestone Precision Sport.
Going into the study, I expected the Michelin to be the victor on the wet racetrack. I was wrong. The Michelin still is one of the smoothest rides, however the newcomers to the group did amazing in the rain.
The Yokohama and the Sumitomo were the clear winners. It was apparent on the track when coming off of the skidpad section and into a long sweeping corner that the Yoko and Sumitomo tires stuck better to the ground, while the Michelin and the Firestone allowed significant over steer.
Think of that as "wagging the tail" of the vehicle. My vote goes to the Yokohama AVID ENVigor or the Sumitomo HTR A/S PO1!
