Probably the BFG simply because of available sizes. See
http://www.nittotire.com/popup_terra_sizes.asp
The 33" Nitto (LT325/60R18) lists minimum of 9.5" "approved" wheel. That's pretty big.
The 33" BFG A/T in LT286/65R18 (
http://www.bfgoodrichtires.com/asset...rain_ta_kd.pdf) lists an 8" wide approved wheel width.
But I do love my Nittos.
