Really interesting document, although I believe they missed the point.
The study should have focused on the difference in tyre pressure due to tempeture and altitude.
Altitude would be particularly interesting!
Good find all the same 🙂

Tyre pressure indicator valve caps
Personally on domestic cars I don’t think it’s worth it.
In other applications it have more significant benafits. For example.
If a military vehicle is taken from the UK after just been serviced placed on a ship and taken on a 4 week exercise to Norway where the tempeture is -20 C the pressure in the tyre will significantly decrease as the air in the tyre decreases, if the driver checks the tyre he fills it up to the correct pressure.
He drives the vehicle back onto the ship a week later where the tempeture is +15 C and the pressure over inflated.
However, tyre pressures are often reduced for driving on snow and rough terrain anyway, so it can also be argued that in this case air is better than Nitrogen.
As for my car, I’ll never concern myself with nitrogen filled tyres, at best if I want to keep an eye on my tyre pressure and I’m too lazy to check it regularly I might invest in those valve caps that show green for +30PSI and Red for -30PSI.
Has anybody ever tried them? I haven’t but have seen them, if they work I’d say they are a better investment than Nitrogen.
Given that they would give an early indication of a puncture especially.

You often don’t have the length of wire to do it but where possible I always tie the two wires to be connected with a reef knot before joining the ends either by solder or crimp.
This enables the wire to be pulled with the pulling force going through the knot and not the crimp thus protecting the connection against inadvertent strain.

The things I carry are more related to self recovery than fixing the car at the roadside.
To give an example I carry:
A rain coat
Head torch
Tow rope
Gloves
Warning triangle
Calume light sticksI also carry:
A leatherman
Spare fuses
Bulbs
Oil
Windscreen washer fluid
Jump leads
Tyre pump
High Viz vest
First aid kit
Fire extinguisher
Note pad & pen(I don’t think I’ve forgotten anything)
I have found that generally the stuff I carry gets used on other peoples cars more than my own (touch wood).
If I ever did breakdown my priority would be to get the car to a safe better equips place to fix it rather than messing about at the road side.
If I was off road driving in the desert it would be a completely different story and a much longer list!

Set it to voltage DC or VDC and connect the red and black to the plug going to the fan.
If you get the wires the wrong way around you’ll just get a -12.4 ish reading when the fan has power
