Correct Tyre Inflation
Correct tyre inflation pressure is essential for safety, optimum tyre life, fuel efficiency, and will
reduce CO2 emissions too.Check tyre pressures (including the spare tyre) using an accurate gauge at least
monthly, and before any long trip. Correct the tyre pressures if they do not correspond to the vehicle
manufacturer's recommended levels for the conditions of use.
Ideally check pressures when the tyres are "cold"; this means that they have not been used in the
last 2 hours, or have covered less than 2 miles at low speeds. Any tyre not in this "cold" condition
is considered "hot". If the tyres are "hot" use a pressure 4 to 5 psi (0.3 bar) higher than those recommended
by the vehicle manufacturer. Do not deflate a "hot" tyre, even if the pressure is above the recommended level.
Tyres gradually lose air inflation pressure naturally; hence the need to check and adjust them regularly.
This regular check can also make you aware of any abnormal loss of pressure caused by things such as:
- A perforation by a screw or nail
- A faulty valve
- A poor seal between the tyre and the wheel rim
Tyres should always be used with the correct pressure, as under inflation may cause irreversible
damage to the tyre's internal components and could eventually lead to a rapid deflation.
Inflation with nitrogen does not dispense with the need to frequently check tyre pressures. If you
are unsure about how to check your tyre pressures, you can call into our workshop for assitance.
Why should your tyres have the correct inflation pressure?
Having the correct inflation pressure is important because it will:
- Optimise road safety
- Maximise tyre life
- Minimise tyre related fuel consumption
- Reduce greenhouse gas emissions
- Improve your driving experience
- Save money!
Did you know that if your tyres are under inflated by 10 psi, as well as being a safety risk, that's
the equivalent of paying an extra 3c per litre for fuel because your engine has to work that much harder
to overcome the extra rolling resistance from its tyres.
