An air wrench set a maximum is not the way to go.
They also found a sheared locking bolt. When shown I figured it failed due to metal fatigue or flaw. Now I suspect they cross threaded it when using the air wrench on the previous set of tyres fitted.
I'd do the job myself (as I used to do) but those wheels/tyres sure are heavy when carrying them 100 yards.

As you say, no excuse whatsover!
Personally, I always undo the locking nut/bolt with a bar & socket, then remove the rest of the nuts/bolts with an impact wrench.
But, I never refit any alloy wheel nut/bolt with an impact wrench & the same goes for any locking nut/bolt.
