These tires are factory fit for my Jeep SRT 6.4. They were a good tire for the first 5000 miles. Then the grip and feel Deteriorated. Wet weather grip got worse and chunks of rubber ripped off. The tire seems to have different types of rubber and it wasn't consistent due to its green status. My Bridgestone tires on my previous BMWX5 were much better. Don't buy these tires for your SRT JEEP. Currently have Toryo tires they are much better.
