i assume higher is better?
Howdy. Given two identical tow vehicles but with different gear ratios where one has a higher one than the other how does that factor into the towing capabilities issue?

Examples, using a F150 of my vintage.
A 3.55 ratio is higher than a 3.73.
A F150 with a 5.4, 18 inch tires and 3.55 rears is rated to tow 8000lbs.
A F150 with the 5.4, 18inch tires, and 3.73 rears is rated to tow 9000lbs.
Does tire size make a difference? Yes. A F150, 5.4, 17 inch tires, and 3.55 rears is rated to tow 8500lbs
Same with a 3.73 is rated at 9500lbs.
Some will say with the 6 speed trany, Rear gears don't mean anything. But they really do. GM example. Suburban with 3.08 rears with a 5.3, 6 speed, tow max is 5000lbs. Same vehicle with 3.42 rears, tow max 7000lbs. 2000lb is a good bit of difference.
