Great Handling Tire

I bought the Tires about 5 months ago and out of all the tires I have had on my 90 Corvette these are the best yet, Handling is great, Ride is very Good and they seem to be wearing very well.

Perfect Sporty All Season Tire

Traction is phenomenal whether its dry or wet out! Braking grip is very good, can easily lock ABS up. The tires handling feels razor sharp like it will go exactly where I want them to. Wear after 5000 miles is almost non existent. Tires comfortable to ride on the highway and backroads.

Unmistakeable Tread pattern

I drive a Mustang Ecoboost, the options most appealing were these vs Bridgestone Potenza. I live in NEPA so I need an AS with good tread, even though I rarely travel in bad weather. So I picked these for reputation and tread. I have hot water in my driveway hose... after washing my son's car for a trip... I asked him to pull my Mustang back into the driveway.. the next day, I backed out and CLUMPS of dried mud from the clearing across the street. It took a full 20 min to wash all the mud and gravel off the driveway. I have NO doubts whatsoever now about my choice!
