The importance of correct tyre pressure
The correct tyre pressure is vital for both safety and for extending the life of your tyre.
You should check your tyre pressures monthly, including the spare and before any long distance driving. Make sure the tyre pressures match the pressures recommended by the vehicle manufacturer.
Tyre pressures should if possible be checked cold. If tyre pressures are checked hot, add 4 to 5 psi (0.3 bar) to the recommended pressures.
In the case of unusual pressure loss, the internal and external condition of the tyre should be checked, as well as the condition of the wheel and valve.
Get a grip on tyre pressures!
Maximum grip on the road is vital for road safety. This can only be achieved with the correct pressure in your tyres. The diagram below shows how much grip a tyre has on the road depending on its pressure.
Tyre pressures - top tips
1 - Safety
Under inflated tyres can not only overheat increasing the chances of it bursting, but also lead to poor handling of your vehicle. Low pressure on the front axle will increase under steer (fig. 1) whereas low pressure on the rear axle will increase over steer (fig. 2).

fig.2 Over steer
2 - Economy
Over inflated and under inflated tyres suffer more damage than those with the correct pressure and need to be changed more often. Even 60% inflation, which is not uncommon, can increase tyre wear and significantly shorten the life of the tyre. Vehicles with under inflated tyres have increased rolling resistance that requires more fuel to maintain the same speed.
3 - Environment
Correct tyre pressure helps to maintain optimum fuel efficiency. This equates to lower CO2 emissions from your vehicle and helps protect the environment.

“Very very happy with the service I got. Five stars as far as I am concerned. After my car was fixed it ran like a dream ..so so happy with my car now. The nitrogen wheels are amazing.

“Very friendly both over the phone and in person. Good advice and sensible prices.”
“Called in on Saturday 4th March as I was wanting to purchase three new tyres and also have a tyre swapped from one rim to another. I had been let down the day before by another company so needed sorting out asap. HRW could not of been more helpful, they sorted the job for me there and then,and the lads took great care with my new alloys. Very reasonably priced also. I was very impressed and will certainly use their sevices again in the future. cheers Craig (CMS).”
