What do you inflate your ten ply KO2s to? Long story short, my local Costco tire center guy said the KO2s ten ply is supposed to be inflated to 50 psi, but the FJ calls for @ 32-36 = if you only inflate to the FJ spec, the sidewalls give out or something like that? Or something happens with the bead/s? Everyone raves about the KO2s, but why buy them if this happens? After checking out Tire Rack's On-/Off-Road All-Terrain Ratings chart and reading numerous compliments about the tire, I am strongly leaning toward the Cooper Discoverer AT3 4S. Thanks for your two cents.
