Out with the old, in with the new. I just picked up a set of 235/75/15 Kumho Road Venture MT KL71 tires to replace my very old BFGoodrich All-Terran T/A tires. The Kumhos are mud-terrain tires and should do quite well off road, especially when the trails get muddy around here in the winter. I honestly haven't even had them up past 40 mph yet, so no word on whether the vibration is better or not. We'll see.
Until then, I will say that I love the way they look. Can't wait to try them out in the dirt.
