Why is it important to check your pressures regularly?
Correct tyre pressure is vital to your safety on the road. Under-inflated tyres affect handling and grip, potentially causing irregular or unpredictable vehicle behaviour. They are also much more likely to suffer from a dangerous blowout, especially on high-speed motorway journeys.
By keeping your tyres at their optimum pressure, your running costs are also reduced. Under-inflated tyres require a bigger force to make them turn, so your car uses more fuel. Additionally, tyres which are not set to their correct pressure wear out more quickly.
So, to benefit from lower fuel bills, longer tyre life, increased safety and reduced CO2 emissions, make sure you check your tyre pressures at least once a month and before a long journey.
Why are Tyres Important?
Most drivers know that snow and ice can dramatically affect their safety on the road. Steering, acceleration and braking are more difficult as normal tyres have less grip in these conditions. However, it is not just these extreme wintry conditions which can reduce your safety on the road. Even cold, damp roads can dramatically affect the performance of tyres, leading to an increased accident risk.
Thankfully though, tyre manufacturers have developed a range of winter weather tyres which are specifically designed to operate in these conditions, delivering improved safety throughout the entire winter period.
While snow and ice present the most obvious hazard to motorists, most drivers change their driving style to suit these conditions.
However, cold, damp roads are visually no different to wet conditions in the warmer months and drivers tend not to adjust their driving style. A tyre’s performance though, is significantly reduced by this combination of conditions, making cold damp roads one of the highest safety risks to drivers.
Air temperature is a crucial factor in a tyre’s ability to perform. When the temperature drops below 7°C, the tread compound in normal tyres begins to harden, providing less grip. The tread compound in winter weather tyres contains more natural rubber and advanced silica compounds to minimise the hardening effect, giving extra grip and shorter stopping distances in cold, damp conditions. Together with sophisticated multi-sipe tread patterns, the combination is one that no summer tyre can match, making winter weather tyres the safest option from October through to March, when temperatures rarely rise above 7°C. This especially applies to commuters and business motorists who are on the roads in coldest conditions in the early morning and evening.
Tests conducted by the British Tyre Manufacturers’ Association found that a car braking at 60mph on a wet road at 5°C stopped five metres shorter, equivalent to more than one car length, when fitted with winter weather tyres.
Checks for all drivers, irrespective of whether they fit winter weather tyres or not, should carry out regular checks throughout the winter to ensure their tyres are in the best possible condition for maximum safety.
In winter tread depth should be checked to ensure it is well above the legal minimum of 1.6mm across the central 3/4 of the tyre, around its entire circumference. TyreSafe has developed the 20p test for a simple and quick way to test your tyres’ tread depth.
Tyre pressures should be checked at least once a month or before a long journey. Pressures should be checked when the tyres are cold (i.e. travelled less than 2 miles) against the vehicle manufacturers recommended levels.
When checking your tyre pressures, give the rest of the tyre a thorough visual inspection for any signs of damage. Look for any cuts, cracks bulges and remove any embedded objects.
A tyre which is more fuel efficient helps reduce your driving costs and CO2 emissions.
There are seven categories, from A, the most efficient which means you will use the least amount of fuel for your journey, to G, the least fuel efficient.
Choosing A-rated tyres over G-rated tyres could reduce your fuel consumption by 7.5%*
Wet braking Performance
Wet braking performance is critical to your road safety as it affects how quickly you will be able to stop in wet conditions. There are seven classes. An A-rated tyre provides the shortest braking distances on wet roads whereas a G-rated tyre will have the longest braking distance in the wet. Driving on four A-rated tyres at 50mph can
help you stop up to 18m* shorter than if you were driving on four G-rated tyres
Exterior Noise Emission
This is the amount of noise made by a tyre when it rolls along the road surface.
The tyre’s exterior noise emission is shown by a series of black waves. Three black waves indicate that the tyre produces the most amount of noise on the scale. One black wave indicates the tyre emits the lowest level of noise on the scale.
