@steter @sibrosan @DerekL @kibcol1049 Ah, yes, I discovered the "might not be services for 150 miles" aspect of North American motoring on Vancouver Island.
The hire car got a puncture. It didn't come with a real spare wheel - it came with some sort of "lite" "get-you-home" half-arsed tyre.
Which was rated for fifty miles.
We were more than fifty miles from the nearest garage.
