1Use the manufacturer recommendation
The correct pressure is usually listed on the vehicle label or owner’s manual. The tyre sidewall maximum is not the normal operating recommendation.
2Check pressure when tyres are cold
Driving heats the tyre and raises pressure. A cold reading gives a more consistent comparison.
3Understand under-inflation
Low pressure increases flex and rolling resistance. It may reduce fuel efficiency and generate excess heat.
4Avoid unnecessary over-inflation
Higher pressure is not a free mileage trick. Excessive pressure can reduce comfort and alter grip and wear patterns.
5Adjust for load when specified
Some manufacturers provide different recommendations for full load or high-speed use. Follow the vehicle guidance.
Practical checklist
- Use recommended pressure
- Check tyres cold
- Inspect monthly
- Adjust for load
- Examine uneven wear
Frequently asked questions
How often should pressure be checked?
A monthly check and before long trips is a practical routine.
Can nitrogen prevent pressure loss completely?
No. Tyres still require regular checks.
Does wrong pressure affect mileage?
Yes, especially under-inflation because it increases rolling resistance.
