Yep, very valid reminder.
Ironically, I passed the same information onto someone when we headed to Coral Bay for a few weeks many years ago. The boat trailer tyres were ancient. One tyre let go just out of Dongara, and the spare was put on, which lasted 2km before blowing. Ended up having to drive to Geraldton to get new tyres, then back to the trailer, then continue the journey.
A 12 hour trip to Coral bay became an 18 hour one!
