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.

Smooth ride!

Very happy with these tires. Much quieter and smoother ride than the Nokian Rotiiva AT's that they replaced - it felt like I was floating down the road. In first 2 hours of driving on snowy and icy roads, traction was excellent and as a bonus, mileage improved from 18 l/100 km to 12 l/100 km!

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!
