Check your current tyre pressure at National
If you want to check your current tyre pressure, you can pop into your local National branch for a free tyre check which includes a tyre pressure check and adjustment.
Either over-inflated or under-inflated tyres can negatively affect your overall driving performance by harming the tyre tread. In some instances, both over-inflated and under-inflated tyres can cause the tyres to become unsafe and illegal to drive.
Every year, dangerous tyres lead to around 5,000 convictions, 900 casualties, and 160 deaths or serious injuries. Not only that, but illegal tyres can actually end up costing you more than the price of a new set: you could face fines of up to £2500 and 3 points on your licence per illegal tyre, not to mention that if you're found to have illegal tyres in an accident, it can invalidate your insurance.
A free tyre check from National can make sure your four wheels are ready for the road. Book in now to stay safe on your journeys.
