Yep, as for Peter:
for around 35 years I've been using my spare as a "quick-fill" reservoir after sand driving: I use a coiled airline I bought from K-mart (for around $7.99 in the 1970's).
Ignore the "max pressure rating" - that's for under load on the road,, hot from driving...., where compression from bumps and corrugations need to be allowed for.
I fill the spare to 120psi or so before each trip, and have had no problem except for one year I left the pressure in after a bush trip and when I next took the spare tyre cover off 12 months later, (ie after a long hot summer) found a small bulge in an otherwise unused tyre - from memory, Bridgestone gave me a free replacement......
I can air up 3 tyres to highway-adequate pressure whilst my compressor tops off the 4th tyre, then
check and top them off at the next service station. That means I get there before all the other trip members arrive and want to hog the Servo's compressor for themselves! (nyuk, nyuk)
