With fuel prices remaining high across the UK, drivers are looking for every possible way to reduce their running costs. One of the simplest and most overlooked improvements available to any driver is maintaining correct tyre pressure. The relationship between inflation and fuel consumption is well documented — and the numbers are worth paying attention to.
The Science Behind the Savings
When a tyre is under-inflated, its contact patch with the road increases and the tyre deflects more with every rotation. This increased deformation requires more energy to overcome, which translates directly into greater fuel consumption. Research from the European Tyre and Rim Technical Organisation indicates that for every 10% drop in tyre pressure, rolling resistance increases by approximately 3%. For a typical family car on UK roads, running all four tyres 10 PSI below the recommended pressure can increase fuel consumption by up to 5%.
What This Means in Real Terms
For a driver covering 10,000 miles per year in a car averaging 40 miles per gallon, a 5% increase in fuel consumption adds up to 125 additional gallons of fuel over the year. At current UK fuel prices, that represents a significant unnecessary annual expense — all preventable with a monthly tyre pressure check. Correctly inflated tyres also wear more evenly and last longer, further reducing your costs.
Other Efficiency Benefits of Correct Tyre Pressure
Beyond direct fuel savings, properly inflated tyres also support your vehicle's braking and handling systems more effectively. Your ABS, stability control, and traction control systems all rely on the tyres providing consistent, predictable contact with the road. Under-inflated tyres can cause these systems to behave less predictably in emergency situations. In short, correct tyre pressure is one of those rare vehicle maintenance tasks that simultaneously saves you money and improves safety.
Enzo Mobile Tyres will check and correct your tyre pressures as part of every fitting appointment. If you just need a pressure check and adjustment without a tyre change, call us — we're happy to help drivers across Nottingham and North London get the most from their tyres.
