After a glorious weekend and with more blazing sunshine on the way, it’s worth remembering hot weather can affect your car tyres.
Hot weather makes air expand which raises the pressure inside the tyre making it less reliable on the roads.
It’s critical to have properly inflated tyres, as this assures the best possible contact between the tyre and the road.
Read your owner’s manual to find the correct tyre pressures, and, if necessary, adjust pressures to compensate for the hotter operating conditions — especially if you’re doing lots of high-speed driving on a day trip or summer driving holiday.
Properly inflated tyres will also last longer and improve fuel mileage.
Because of summertime’s higher temperatures, the air pressure in a warm tyre rises. Why? Because air is a gas, and gas expands when it heats up.
Keep this in mind if you are checking tyre pressures. The given tyre pressure specifications are for when the tyres are cold, therefore the pressure should ideally be checked when the tyres are cold.
Also, an improperly inflated tyre can heat excessively, potentially leading to a blow-out on the highway.
