Low load/speed rating bfg ko2 vs high bfg ko2

Hey guys,

Time to swapmy Mickey Mtzs around and want to go all terrain.
Recently I've been quoted $310 for LT285/75r16 bfg ko2s with a load/speed rating of 116/113R. Whereas I could fork out the extra for either a higher rated ko2 or Mickey Atz p3 ($370 a piece).
I currently drive a mav/gq and don't tow too much, and I want to do more higher tours/sand/4wding.

What do you think would be better? I can fork out the extra $300 for 5 tyres total, but don't want to if I don't have to. (tax return is coming up Hehe)

Thanks in advance!!
Riley
