Makes me think of a joke: this engineer takes his tire into the Goodyear store to get it balanced. While he's watching the work get done (...because we always have to watch to make sure it's done right -lol) the young tire tech takes the weight displayed and splits it in two, putting half on the outboard face of the rim and the other half on the inboard face of the rim.
He asks the engineer: "do you know why I did that?"
The engineer clears his throat and says, "why, yes, in fact I do. If you were to put all the weight on one side, the offset of the wheel introduces a moment, the resulting force being proportional to the lateral distance of the offset and increasing with vehicle speed. The resulting magnitude can create a disturbance which can magnify, particularly at it's resonant frequency and be felt in the car at certain speeds, generating customer pleasability issues, erratic tire wear and/or durability concerns".
The kid looks blankly at the engineer and says "yeah. Cause if I don't it'll wobble".
