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.

The best tires money can buy

When I tell you I'll never buy another tire again. I mean it considering what I've experienced with these tires. I already knew that these tires were very reliable. Due to me having them on my motorcycle & previous vehicles. But Monday sealed the deal for me. I ran over a collated nails in a construction zone. Totally unaware of it, my tire began to go flat. When I looked at the tire I could only see for nails. But when I took my car to the tire shop & they removed the tire. You could see the actual extent of damage that occurred. And just how well these tires held up, keeping my son & I safe. Needless to say I purchased another set of the same tires with a warranty. I'll vouch for these tires every single time.
