Hi.
In line with your offer to ask you "anything", is it possible to know what proportion of a car's weight is lifted when you jack up on one side to change a wheel? Presumably some of the weight is being taken by the two wheels that remain on the ground. I ask this because, for a different job unrelated to the car, I want to buy a small hydraulic bottle jack (the smallest smallest possible to fit into a particular space) and I'm wondering if the max lift of the bottle jack is less than the total weight of the car, would it be safe to use it for changing a tyre.
As always, many thanks in advance, Philip
