I am about to replace the bfg hydro-trails on the truck.

I have the BFG AT's on my frontier and love them to death.

I am putting BFG AT's (31's) on the Xterra.

Are you guys buying 4 or 5? I know you are not supposed to run a smaller tire on the LSD rear would it be okay in an emergency to run the stock 265/70/15 on the front?

Regards

Hayden
