Yes exactly - conflicting advice!

Here are the specs for the 325/55/22 versus stock:

Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
315/70-17 8.7in 17.2in 34.4in 108.0in 587 0.0%
325/55-22 7.0in 18.0in 36.1in 113.3in 559 5.0%

Here are the specs for the 325/50/22 versus stock:

Specification Sidewall Radius Diameter Circumference Revs/Mile Difference315/70-17 8.7in 17.2in 34.4in 108.0in 587 0.0%325/50-22 6.4in 17.4in 34.8in 109.3in 580 1.3%

So the 325/50-22 is the closer size and will lift the truck by approx 1/4" and a 1.3% speedo error - whereas the 325/55-22 will lift the truck by 3/4" and give a 5% speedo error!
