Driving with tyre pressure at 180 kPa (26 psi) is generally safe for short distances at low speeds, but it depends on the manufacturer's recommended pressure. Most passenger cars require 200-250 kPa (29-36 psi). Underinflated tyres increase rolling resistance, reduce fuel efficiency, and risk overheating or blowouts.
If your tyres are at 180 kPa, follow these steps:
- Check your car’s recommended pressure (found in the manual or door jamb).
- If 180 kPa is significantly below the recommended level, avoid motorway driving.
- Drive cautiously below 50 mph to a nearby garage, avoiding sharp turns or sudden braking.
- Reinflate to the correct pressure immediately.
For example, a Ford Focus typically requires 220 kPa (32 psi). Running at 180 kPa for extended periods could damage sidewalls. If the garage is more than a few miles away, consider using a portable compressor or calling roadside assistance. Never ignore underinflation—it’s a safety risk and can lead to premature tyre wear.
