BFGoodrich All Terrain TA KO2 235/80 R18 Land Rover Defender 5,000 miles January 27, 2021
Great tires in wet, mud, snow and ice if you ant to go forwards. never had a problem. If you want to stop in the wet, snow or ice, they are the worst tires I have every used. They lock up at the slightest brake pressure and offer no retardation. I tow a trailer and they are even worse then as the trailer ends up pushing the Land Rover before the trailer brakes operate. Cannot comment on wear as I have only done about 5000miles with them. I would NEVER buy again.
