Incorrect tire pressure—especially under-inflation—increases rolling resistance, making the engine work harder and consume more fuel. This can reduce mileage by up to 10%.

Recommended Tire Pressure for Swift in Pakistan:

30–32 PSI for front and rear tires check the sticker on the driver’s door frame o r owner’s manual.

Common Mistakes:

Ignoring tire pressure during oil changes.

Using mismatched tire sizes o r worn-out tires.

Fixes:

Check tire pressure monthly, especially before long trips.

Use digital tire gauges for accuracy.

Get wheel alignment and balancing checked if fuel economy s suddenly.
