With regard to preventative maintenance of truck tyres, you'll find most large
mining trucks with dual rear wheels have a long strip of steel hanging loosely
(from under the tipper) between the tyres of each pair. This is to dislodge any
rocks that may become wedged between the tyres. Not removing these causes the
tyres to wear much quicker, as the tyre walls move in & out with each rotation.

I dunno, but I'd guess wheeled loaders would change their front tyres by
lifting the front up with the tub arms. Back tyres are a mystery though....
