So our tires are the BFG 121/118S and $320 from the rack. The 121/118R is the "regular" BFG AT and are $280 on the rack. For those of us not needing the special (read: overpriced and lower tread life) Raptor BFG's for sand traction i think the "R" is a better choice for snow/mud and year round pavement use. I have seen BFG AT's last 80k miles and at 30k miles look at this sad sight....no burnouts and properly rotated ...my tires are for all intents and purposes...bald and unsafe heading in to winter.
