What are the best for All-terrain and especially for snow??

BFG All-Terrain, Nitto Terra Grapplers or some Procomp tires or somthing else?

Bfg and Goodyear are great because they have the Severe Snow rating on them. This is indicated by the snowflake symbol on the side wall of the tire. I also think that the pro-comps carry this rating.

seems like the nitto's have the snowflake too, I want 315s but then I dont want to lose performance time in 1/4. Will the 315s really make a difference as a oppose to 295s v.s. my stock 265s?? Thats why im leaning towards the 295s, not sure??!?!?!?

I've had a few sets of the Pro-Comps and they are an excellent tire-imo. I ran them in Colorado and the sever weather rating lived up to its name--drove a 2wd f-150 over vail pass in a blizzard. No chains. Manual tranny and a 4speed. Just cruised it on out in 3rd. For the $$, a great investment. Never had them in a load range E, however. I will be trying them on my ram when this set of cheapos wears out.
