4 years and 110k miles before replacing them… can't imagine giving them anything but a 5 star review after that.

Don't buy KO2's. They wear quickly. Started cupping early on. I rotate every 3k miles and service my vehicle regularly. Had suspension checked. No issues. I have a friend with the same issue.

The worst tires I have ever put on my truck period. 15000 miles and tire tech says they are worn out. They will not stand behind warranty because I missed 1 rotation. DO NOT BUY THESE! Going back to duratracks.

Excellent tires, I've been using them for years! There's a reason they've been around since the 70's. Good looking, excellent performance and durability.

really good for everything and specially for off road use

I've had a set for over 2 years and have 53,000 miles on them so far with 5-7k more on them. They have stayed balanced and are quiet on the highway. I highly recommend them.

My first set of KO2's lasted 102,000 miles! I just replaced them a few months ago. I thought the tread wasn't as deep, and now, I'm sure these tires aren't as good as my first ones. Something changed. I'm not happy at all.

I bought five tires, Two sizes bigger than stock two years ago and you can hardly tell there is any tread loss. They ride nice and Have been very durable. I've had them off-road on dirt and rock and I've never had a puncture. Great tire.

I have owned multiple sets of these tires since their inception. From Moab to job sites, never had a problem. Never had a flat. Never had a blow out.

Side wall failure took truck to a bf goodrich dealer in November was right at the 50000 mile warranty had cracks all around the side wall blew out on the way home from work
