[QUOTE="Anybodyhome, post: 445369, member: 19161"] Tongue weight is the downward force the weight of the trailer's tongue on top of the hitch ball. Tongue weight should be 9-15% of the gross trailer weight. The tongue is on the trailer and tongue weight applies to the ability of a vehicle to pull a trailer. Gear ratio effects tongue weight as it applies to a trailer and the vehicle's ability to generate enough torque to get the trailer moving [I]and [/I]to get the trailer to slow down. For example, a 3.21 JK Sport has a lower towing capacity and tongue weight because the gear ratio will put an undue amount of stress on the engine in the lower gears trying to get the JK and trailer weight moving. The 3.73 and bigger gear ratios have higher towing capacity and tongue weight because of the amount of torque they can generate to get the JK and trailer going. So, your bicycle rack and its ability to hold a couple hundred pounds of bikes is not a function of tongue weight at all. Hell, I'm close to 300lbs and I stand on my rear bumper all the time to load my roof rack. I could probably jump up & down on the hitch and it wouldn't bother it at all. The capacities are used as safety features. If you took a 3.21 geared jeep and hooked a 3500lb small trailer to it, you'd probably be close to red-lining the transmission thru the first 3 gears just to get it going. [/QUOTE]
