One thought on “BFGoodrich Mud-Terrain T/A KM3 Tire Review

  1. I put a set of BF Goodrich tires on my F250 FX4 and could be happier with the performance of this tire. The KM3 is the best mud tire I’ve ever owned, it has a lot of bite and the threads clean themselves out very efficiently. The truck is used for farm a agriculture purposes and is always in muddy pastures and fields; tire spin is a thing of the past. Although this tire is not meant for the highway it’s performance there is just as good as in the fields. Ride quality is very good with very little tire sing. If you are looking fo a tire that spends 75 percent of the time off road then I highly recommend the KM3. If you have a pretty boy city truck then you might want to look at something made for highway more.
