As the UK braces for another heatwave with temperatures forecast to hit 34C, motoring experts are warning drivers to take extra care on the roads. Tyres can be vulnerable in the heat, and the likelihood of blowouts and vehicle-related problems rises during periods of intense heat.
James Harding, a tyre expert at Blackcircles.com with over 16 years of experience, said: "As temperatures rise, many drivers are unaware of how much strain summer conditions put on their vehicles. From tyre pressure fluctuations to overheating engines, small oversights can turn into major issues."
How to Prepare Your Vehicle for Summer Driving
Check Tyre Pressure Regularly
Warm weather can impact tyre pressure, potentially diminishing grip, accelerating wear, and heightening the danger of a blowout should tyres be over- or under-inflated. As the temperature climbs, the air within your tyres expands, pushing pressure up by approximately 0.1–0.2 bar for every 10°C. For the most precise reading, inspect tyre pressures while the tyres are cool, either before setting off or after the vehicle has been resting in the shade, and always inflate them to the manufacturer's recommended levels, as outlined in your owner's manual or on the fuel filler cap.
Top Up Fluids
Heat places additional stress on your vehicle's engine, so ensure you regularly monitor oil and coolant levels, as insufficient fluid levels can result in overheating and mechanical failures. Motorists should also maintain their screen wash to preserve clear visibility amid insects, dust, and pollen.
Guard Against Sun Glare
Sun glare is responsible for thousands of collisions annually, so clean your windscreen both inside and outside, replace worn wiper blades, and store a pair of sunglasses in your glovebox to enhance visibility.
Monitor the Dashboard
Summer weather can push your vehicle's systems to breaking point. If any warning lights illuminate on your dashboard, particularly temperature or engine alerts, pull over safely and investigate or summon assistance before any damage escalates. If you cannot identify a warning light, be certain to look it up or contact a qualified mechanic.
Check Your Air Conditioning System
A working A/C is crucial not merely for comfort but also for demisting windows, which can fog up in the heat when moist air contacts a cooler surface. Guaranteeing you have a complete range of vision is essential when driving. If your system isn't cooling properly, it may require re-gassing.
Prepare for Your Journey
With greater numbers heading out on summer excursions, roads become more congested, particularly around major motorways. To prevent lengthy delays and minimise the risk of stop-start traffic, which can overheat engines and deteriorate the brakes, check your route on traffic applications and arrange to drive during off-peak hours.
