In modern vehicle safety, Run-Flat tires let you keep driving for a short distance at limited speed even after a sudden loss of pressure. Whereas a regular tire collapses onto the rim when punctured, Run-Flat designs use reinforced sidewalls (self-supporting) or support rings that sit on the wheel to hold shape and preserve steering control. Depending on the manufacturer, typical guidance is up to 80 km of range at a maximum of 80 km/h—enough to reach a service point safely.

At the heart of the tech is the strengthened sidewall: heat-managing rubber compounds and a high-load carcass prevent collapse even with zero pressure. TPMS (Tire Pressure Monitoring System) is mandatory, because you can still drive on a punctured Run-Flat and need an alert to know you’ve lost pressure. Wheel compatibility and the automaker’s approval matter, too; many models specify RFT-compatible wheels.

Pros (Why Drivers Choose Them)

Safety: In a blowout, handling remains more predictable; you can move to a safe spot without panic.

Time & convenience: You avoid roadside tire changes, a big plus at night or in bad weather.

Cargo space: Often no spare is needed, freeing up trunk volume.

Cons (What to Consider)

Ride & noise: Reinforcements can make the ride firmer and increase road noise slightly.

Weight & efficiency: Extra material adds some weight, with small effects on fuel/range.

Cost & repairs: Purchase and repair costs are typically higher; sidewall damage is often non-repairable.

Don’t mix types: Do not mix RFT and standard tires on the same axle; ideally all four should match.

Who Benefits Most?

Highway travelers & families: Confidence to reach a workshop after a puncture.

City drivers: New cars without a spare and those wanting more trunk space.

Fleets & premium vehicles: Many models offer OEM-approved RFT packages.

Quick Take

Run-Flat tires deliver limited post-puncture range, stable control, and time savings. In return, expect trade-offs in comfort, weight, and price. With the right wheels, a healthy TPMS, and OEM approval, they’re a practical, safety-forward choice for everyday driving.
