Hi Kiwi Kia,
The reasons chains damage vehicles are:-
Being the wrong size for the tyre. It doesn't matter what you do they will never fit correctly and you risk them coming off.
Not re-tensioning them after fitting. The chains settle and find their place on the tyre after a few rotations so it is necessary to stop and re-tension them.
When you have clipped them up, tie the end off securely. I've heard a lot of vehicles bang banging down the road because the end of the chain is whipping the guard every time it goes around.
If your driving in snow and ice a tighter fit of your chain is a good idea but for mud, particularly sticky crap, having a looser fit enables the crap to be flung off; same principle as mud tyres, clear treads give you traction.
When a tyre fitted with chains is rotating the centrifigul effect wants to throw the chain off the centre of the tyre tread so brake would be fine. An off-road vehicle would have extra clearance in the wheel arches to allow for this without any problems. If there is a problem
check for the correct size, tension or fitting.
