I've had KO2's since the 90's. First on a half ton Chevy, then a Jeep 4dr Wrangler. Always loved them and considered myself a customer for life.

However, the last two sets had balance issues that just wouldn't quit. 4+ oz of weight on each tire to get balanced and rebalance required every 3-4k miles. Just drove me crazy. So I finally bit the bullet and switched to Toyo's this past summer. All balance with less than 0.5 oz weight and run find, although a bit more noise.

Shame really, I loved the KO2's...
