Maybe try some TreadWrights?
Here's a link to their site. https://www.treadwright.com/default.aspx
They have BFG AT KO knockoffs, that are better in terms of winter traction due to the crushed glass and walnut shells that they mix in with the rubber for the tread. Obviously the tread wears a little faster than your standard BFG, but you pay a bit less anyhow.
From what I've read, lots of folks have had good experiences with the tires, and with customer service.
Compare the price... the price of a BFG AT KO at about 150 a tire, while a TreadWright Warden AT with the same pattern goes for about 100 a tire. That's 200 bucks in savings right there.
Or some Super Swamper Trxus STS. Them buggers are expensive, though.
And no, I am not a tire saleman. Just throwing some options out there.
If you like running the BFG's, then go ahead and get them. Nothing wrong with them.
