Modern tyres are for the most part excellent, but that doesn't mean they don't lose pressure and go flat over time, often at a pace imperceptible to the human eye.
Properly inflated tyres are also safer and will return better fuel economy so it's always worth keeping an eye on those black orbs of rubber.
Most modern cars will come with some built-in tyre pressure sensor gauge but there are still plenty of cars on the road with no feature to check the tyres. This is why we've found the best aftermarket smart tyre pressure monitors that are guaranteed to fit your car.

What you need to know about smart tyre safety monitors:
How do they work?
It's fairly simple, the sensors screw into your tyre (where the standard valve cap once was) and this allows them to check temperature and pressure. The sensor has a wireless transmitter that sends this data to the receiver. The receiver can either be a satnav, smartphone or separate screen that will show this data and inform you of any problems.
Do they need charging?
While none of these monitors needs to be hardwired to your car (like a dashcam), they do require power to work, usually from batteries. The sensors will more than likely use button cell batteries (the type found in some wristwatches) because of their size, but they should last for ages. If your key comes with a special monitor then that will need some form of power, often a USB/12V port. If you're using one that connects to another screen (like a satnav or smartphone) then that device will obviously need some charge to work.
Are they suitable for all cars?
Most modern cars do come with in-built tyre pressure monitoring so there is no need for an aftermarket system. If your car is missing this feature then these aftermarket tyre safety monitors should fit. All they do is take the place of your car's standard tyre valve cap meaning they're pretty universal. Be careful, however, some of these monitors are incompatible with certain valves, with aluminium valves being notably suspectable to damage.
