I can see a problem here. The OP will train all the present staff to change wheels and, presumably, make sure that they have all the neccessary equipment with which to do it; including torque wrench, gloves, high viz vest etc. The problem will be keeping it up: Will he train all new drivers before he lets them on the road, and what about agency drivers. Before they change a wheel they will, of course, do a risk assesment to take account of traffic etc.
Hardly any haulage companies would expect a driver to change a wheel these days for very good reasons. If there was an accident involving a loose wheel which a driver had changed, the court would examine all the circumstances, inclding training and equipment. In fact many haulage companies won't even allow a driver to change a light bulb - prferring to pay for a fitter to do the work and take the responsibility.
A sad reflection of today's compensation culture.
Some vehicles do not carry spare wheels. Notably Fire appliances.
The world has gone mad if that is the case.

Well according to those "Police Camera Action" type of TV programs, there is no where safe on the fringes of any motorways..![]()
