F 250 Tire load rating.
I am looking for numbers on load rating of 17 vs 18 LR E tires on the F 250. What would i grain, if any, by going from 17" to 18" tires?

You have to go size by size to determine. I am going to go with 265/70R17 vs 265/70R18, and then 265/70R17 vs 265/65R18. All numbers are from BF Goodrich KO2 Tires.
Going from 17 to 18, you go from 3195lb (17") to 3525lb (18") but you also gain 1 inch in overall tire height, effectively reducing your gear ratio slightly.
Now, keeping it even sizes, comparing 265/70R17 and 265/65R18, you go from 3195lb (17") to 3305lb (18"), and you lose (not loose, that refers to lug nuts that are not tight) .1" of overall tire height.
