Tyres should be inspected at least once a month and before any long journey. Checks should include checking the air pressure, overall condition and tread depth.
Tread depths should be checked to ensure they meet the legal minimum regulations. Pressures should be checked in line with the vehicle manufacturers' recommended settings. Take care to increase the pressure if the vehicle is heavily loaded as shown in the car maker’s recommendations. The tyres should also be given a thorough visual inspection to look for any cuts, lumps or bulges. Also look for any objects embedded in the tread which should be removed.
Adequate tread depth is essential for good grip on wet roads as the tread pattern helps to remove water from between the tyre and the road surface. Drivers with insufficient tread depth face longer stopping distances, reduced grip and an increased risk of aquaplaning.
To stay safe on the road your car needs to have the correct tyre pressure. If the tyres are under or over inflated then handling and grip will worsen, potentially causing irregular or unpredictable car behaviour. The wheel rim and tyre will be more susceptible to impact damage. Over-inflation results in less comfortable ride, a reduced area of contact with the road giving less grip in the day and accelerated wear on the tread centre.
The vehicle manufacturers' handbook contains this information, as well as it being available inside the fuel filler cap or driver's door sill. Many tyre retailers will also be able to provide this information. Alternatively, car drivers can obtain the correct tyre pressure for their car by visiting your nearest Autometric outlet.
A. Irregular wear can be caused by a number of factors. Repeated scuffing of tyres against kerbs, misaligned steering, aggressive driving, the over- or under-inflation of the tyre, worn suspension parts, are just some reasons. There are so many variables that there is no one single answer. Tyres should be checked regularly for any signs of wear and replaced accordingly.
