For £9.99 I purchased a neat little device which is an extension to the spare wheel tyre valve....braided hose....connects and extends way out beyond the spare wheel well. CLIPS on the carpeted side on the inner wing with velcro and has a little warning tab/valve (colour green) to show tyre inflated to correct pressure 60psi, changes colour if pressure drops. Just by looking in the boot, I know the spare is fully inflated to correct pressure and never need to empty the boot to get to spare to check the pressure......(you never do it anyway).....My spare has actually NEVER been used, thankfully.Confidence part is that if I EVER need the spare at least I know that it is usable.
