The risks of underinflated tires

Model: (Various brands) Various
Part: Tires

Video tutorial

This video tells us about the risks of underinflated tires: it is a dangerous and also expensive thing. Braking distances increase due to the smaller contact surface; steering response becomes less precise and there is a greater likelihood of both understeer (the car goes wide in corners) and oversteer (the rear of the car slides); the risk of aquaplaning also increases, as the tread cannot drain water sufficiently.

There is also a risk of "tire bead unseating", meaning that the tire could come off the rim in a corner or during a very abrupt maneuver, causing total loss of control. Rolling resistance requires more energy, and therefore more fuel is needed to move the car; the tire wears irregularly, much faster on the sides.

Natural causes of pressure loss include: osmosis (natural air loss through the tire), temperature fluctuations, stresses such as potholes and irregularities.

Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
