Again, to all those running 55 or above, for comparisons sake, here is the table for my 305/70-17 E Nitto's:
35 - 2405
40 - 2605
45 - 2780
50 - 3000
55 - 3220
60 - 3440
65 - 3640
So, as you can see, unless you really have a need to have your tires capable of carrying over 14k lbs, you prolly don't need them at 65 psi. Just my opinion.
