Tyre Pressures 
Tyre Pressures: Why They Matter and How to Check Them
Keeping your tyres at the correct pressure is one of the simplest yet most important parts of car maintenance. Properly inflated tyres improve safety, fuel efficiency, handling, and tyre lifespan. At Freeway Fast Fit Tunbridge Wells, we recommend checking your tyre pressures at least once a month and before long journeys.
Why Tyre Pressure Is Important
Driving with under-inflated tyres can cause several problems:
- Reduced handling and grip, making your car feel less stable, particularly on wet or winding roads.
- Increased risk of blowouts, especially at high speeds on motorways.
- Higher fuel consumption because under-inflated tyres create more rolling resistance.
- Faster and uneven tyre wear, reducing the overall life of your tyres.
- Increased CO2 emissions due to higher fuel use.
Maintaining the correct tyre pressure helps ensure safer driving, longer tyre life, lower running costs, and a smaller environmental footprint.
How Tyre Pressure Affects Performance
Tyre pressure influences several key aspects of your vehicle:
- Speed capability: tyres perform safely up to their rated speed when correctly inflated.
- Load carrying capacity: Overloading tyres or running them under-inflated reduces their strength.
- Handling and braking response: Proper pressure ensures predictable steering and stopping distances.
- Overall safety: Correct inflation reduces the likelihood of tyre damage and accidents.
How to Check Your Tyre Pressure
- Always check your tyres when they are cold, before driving, or at least three hours after use.
- Use a reliable tyre pressure gauge to measure each tyre.
- Compare readings to the manufacturer’s recommended pressure found in your vehicle handbook or inside the driver’s door frame.
- Inflate or deflate tyres as needed and repeat the process monthly and before long journeys.
Tyre Pressure Monitoring Systems (TPMS)
Modern cars come equipped with a Tyre Pressure Monitoring System. This alerts you if tyre pressure drops below the recommended level. At Freeway Fast Fit, we can assist with resetting your TPMS and fitting sensor valve units to most vehicles.

FAQs About Tyre Pressure
How often should I check my tyre pressures?
You should check them at least once a month and before any long journey.
Can I check tyre pressure when the tyres are warm?
It is best to check tyre pressure when the tyres are cold for an accurate reading.
What is the correct tyre pressure for my car?
Check your vehicle handbook or the sticker inside the driver’s door frame for the manufacturer’s recommended pressures.
What happens if my tyres are under-inflated?
Under-inflated tyres reduce handling, increase fuel consumption, cause faster wear, and raise the risk of a blowout.
Can over-inflated tyres be dangerous?
Yes. Over-inflated tyres can reduce grip, increase wear in the centre of the tread, and make the ride harsh.
How does TPMS work?
Tyre Pressure Monitoring Systems alert the driver when tyre pressure drops below the recommended level, helping prevent accidents and tyre damage.
Do I need to adjust tyre pressure for different loads?
Yes. Heavier loads require higher tyre pressures, as recommended by the vehicle manufacturer.
How do I reset my TPMS?
Freeway Fast Fit can help reset your TPMS after adjusting tyre pressures or replacing tyres.
What is the effect of incorrect tyre pressure on fuel economy?
Under-inflated tyres increase rolling resistance, meaning your car uses more fuel and produces more CO2 emissions.
Can I rely solely on TPMS for tyre safety?
TPMS is useful, but you should still manually check your tyres monthly, as TPMS may not detect gradual pressure loss or all types of tyre damage.
