It's interesting to see the thoughts around whereby swapping out spare tyres on ones vehicle as was originally built as per vehicle spec? don't see or understand the logic here other than what you are doing, is at ones risk, noting extensive testing and validation was conducted to arrive at the spare tyre you have in the boot. all space saver tyres have speed limitations attached too. if you change your spare to another size of your choosing - and you're driving with the spare tyre on due to a flat, (other than OEM), and you're involved in an accident, most if not all insurance companies will look at ways to waive your rights due to this (even a spare tyre) - buyer beware!
