Replaced the OEM Pirelli 'junk tires' with the ST right after they hit the market. I am about to hit 50k miles and they look like I will need to replace them in the next 5-7k miles. VERY happy with the tires. I have a minimal drop kit on the truck which changes the geometry for the better. the tire is quiet, handles nice, good in water and in Oklahoma snow. Great tire. Keep them properly inflated and they will last a long time.
