84 FJ60 stock suspension 15"wheels: I am purchasing BFG All Terrains, should I get 31 X 10.5 or 33s ???. Will the 33s fit, and if so, are'nt they a little big for stock suspension. What would be the best tire size for my situation. I will not be buying a suspension lift for a very long time $$$$. I look forward for your suggestions.
