Do any car manufactures include TPMS with spare tyres? I presume they don’t.
Ideally, spare tyre pressures should be checked intermittently. A yearly check at service time seems insufficient. I wonder what proportion of car owners actually check the pressure of their spares (if they have one).
I posted the above in the topic ‘Alloy vs Steel Wheels’ in 2021. It is so much simpler to check the spare’s pressure via an extension tube. I had to also buy a short right-angled connector to avoid bending the valve stem too much. Some spare wheel wells may not have enough room for the above, but I have used it in 3 different cars. It is better than risking a back injury in myself or the car service workers.
