The Sentinel kit comes with external sensors. They screw onto the valve and you fit them yourself. Internal sensors sit inside the tyre, so a tyre shop fits them and balances the wheel. We quote those by email.
The Sentinel watches 4 tyres. To watch a spare as well, pick a 6-sensor kit: Aura A6 or Guardian 6.
It watches 4 tyres, so it suits a vehicle on its own. For a car and van, see Aura A6 or Guardian.
