How much would a set of 4 bfg m/t 31x10.50x15 cost. Will they fit on a stock 82 f150 and how will they do in the snow.

 

Yep they will fit. 4 Wheel Parts has them for $120.95 a tire. http://www.4wheelparts.com/product2....s=BFGO&cat=TIR
They're expensive but good. Otherwise you could go with a Uniroyal Laredo M/T. I have a set of 265/75/16 on my truck and they cost me $115 a tire mounted and balanced. These are good tires they are great in snow and mud. They area also predrilled for studs too.
