Just to add to the thread regarding the wheel studs. People go very 'health and safety' on the things, on the premise that there's no such thing as too tight. Well of course there is. Look at the design of the wheel, and hub, and you'll notice that the hub itself sticks out, and the central bore of the wheel actually sits on this. The wheel studs are there literally to hold the wheel
against the hub. They don't - in the strictest engineering sense - hold 'any' weight (of course they
do take
some force in practice, otherwise they'd be made from plastic). But that's the function of wheel studs - to hold the wheel
against the hub, thus allowing the hub to take the weight, as opposed to actually holding the wheel
on the hub. For the same reason it's actually dangerous to fit a wheel from another vehicle with even the same PCD, but a different central bore. Because in that instance the wheel studs are actually taking the full weight of the car.
