woodchuck1,
Some info for you if you don't already know it.
Your 2500 came with 245's OEM at 3042 lbs capacity with 80 psi each tire. 2 times the 3042 is where your 6084 rear axle capacity comes from. Your axle stand alone is rated at over 10,000 by it's manufacturer. Your rear axle is identical to the 3500 SRW rear axle which has a 6800 - 6900 rear axle, depending on the truck's model year, as the 3500 SRW came OEM with 265's at 3415 lbs capacity with 80 psi each tire. The very same axle/dia is used on the 3500 DRW trucks with a different wheel mounting plate welded on the end for attaching the dual wheels. Your axle is very strong!
Tire dia's, widths, and circuference (Distance for one revolution) for your 2006 truck:
245's = 30.47" high, 9.65" wide, 95.72 circumference
265's = 31.65" high, 10.43" wide, 99.43" circumference
285's = 32.83" high, 11.23" wide, 103.13" circumference - 3750 capacity -(don't use as it hits and is more "wallowy"/"wandering" due the the greater distance from the tire bead to the tread surface giving more flexing) A couple of the reasons why few keep the 285's on when carrying a heavy TC!
Speedometer and shift points changes from 245's to 265's is 3.9% or you will be going faster than indicated and will shift/lockup/overdrive at a higher speed by 3.9%
