Verified Purchase

Can't go wrong!

Purchased these tires to replace OEM Michelin for my F350. Extremely happy with them. They handle better than the OEM tires. Like everyone, I have to run these tires on the highway, and they are as quiet as the Michelin road tires, but feel more confident. Strongly recommend!

Amazing tires!

So far sooooo, great! I own a 4x4 Mercedes Benz Srinter 2500. I had a set of K03's installed before hunting season. Awesome all around traction in wet, snow and ice. I live in a remote area so I'm in 4x4 almost everyday. Not noisy on the highway either.

The Only Tire You wil Need!

I have using BFG All-Terrian Tires since the early 80's and they have never let me down. I have a 2015 GMC Sierra 1500 that came with the KO2 tires, I just replaced them after with the KO3 tires. The KO2 had 121,000 kms on them and their warranty was for 80,000 kms, I would only recommend BFG All-Terrian KO3 tires based on my 45 years of driving with them!
