I replaced my BFG ATs with a set of the new Yokohohama ATS last winter and can only say good things about them. On my truck they outperform the BFGs in every respect but in Canadian Winters they really shine.

I was driving 130 miles a day throughout the Canadian rocky mountains during winter last year with my JDM Pajero running the new Yoko ATS. Also did several runs 1000 miles roundtrip across the province wich involves driving through 5 different high mountain passes. I never lost traction once in the snow and the only time I would touch the transfer lever is for putting it into all wheel drive when it got really icy or I was driving the road before the plow.

If you want an all terrains for winter driving, you can't go wrong with these.

The BFGs might be better for wear though. I have put 30K miles on the Yokos in the last year rotating at every oil change and I am down to 12/32 from 18/32 which isn't bad if you ask me. I am planning on getting a set of the MTs for next summer and using the ATS for winters.
