Summit Racing has them listed for $240 per tire.
I'm torn. I want the 255s for the look, longer life (per rotation per mile), and a little better highway performance, but I have a hard time spending this cash on something that simply gets used up. If I stick with the 235s I can get the K02 AT (this is my daily driver) tire for about $400 less for the set, and I can swap my current tires to a vehicle that is used less, and continue this every time I get new tires. I also really trust the KO2 on ice. I wouldn't mind one of the Coopers in 255, but they are even more expensive, and I'm not sure I like the sidewall look, and I have no history at all with these tires.
All I know is that going from some other tires that said they were snow/ice rated, back to the KO2s was a night and day difference in every respect. That experience makes me want to stay with the BFGs...... I want the 255s though. They just look so good!
