While the weather may keep jumping from hot glorious sunshine to overcast and rainy, the summer holidays are now upon us. Many Kwik Fit customers are thinking about packing up the car, hitting the road, and getting away for a while - forgetting the cares of the world for a couple of weeks. But with so many things to consider such as bags, suitcases, sleeping bags, camping stove, suntan lotion, hats, rain coats, wellies, buckets, spades, food for the cat or the dog (you get the general idea), we can be forgiven for forgetting to think about the air pressure in our carís tyres, canít we?
Itís easy to simply say Ďyesí, of course, everyoneís busy and itís easy to forget these things, right? With the kids and your loved ones in the car, the answer from Kwik Fit is an unequivocal NO! Ignore your tyre pressures and you wouldnít forgive yourself if something went wrong while driving, would you?
Donít let your tyres let you down
At Kwik Fit, when it comes to tyres weíve seen and heard it all and thereís a misconception among many drivers that you donít need to bother checking tyres regularly. Itís estimated that around two thirds of all UK drivers donít check their tyres for wear and tear, or make sure theyíre correctly inflated either in their everyday life, let alone before they set off on their holiday.
This is especially true of drivers whose vehicles are fitted with Tyre Pressure Monitoring Systems (TPMS). But even if you have TPMS you still need to make sure you regularly check your tyre pressures.
In our latest tyre safety article, we explain not only why itís so important to check your tyre pressure regularly, but also why itís crucial to adjust your pressures when your car is fully laden for your holiday.
So exactly why are tyre pressures so important?
Simple. Itís mainly and most importantly about you and your familyís safety.
Itís a well known fact in the automotive and tyre industries that under-inflated tyres affect your carís handling and braking, and not in a positive way. Under-inflated tyres have a direct impact on how quickly your vehicle can come to a full stop when braking. The result is often significantly longer stopping distances. In wet weather conditions this can be up to four car lengths.
Stopping distances are also influenced by whether your car has premium or budget tyres fitted. Four car lengths is clearly an unacceptable distance to travel when you need to stop quickly and safely - such as on a fast motorway, or if a child steps out in front of you as youíre driving around your holiday location. The consequences are frightening and all too obvious.
Over-inflated tyres, on the other hand, dramatically increase the risk of high-speed tyre blow-outs Ė with consequences none of us want to ever have to deal with. Not a summer goes by where we don't hear about UK holiday makers both at home and abroad becoming victims of unforeseen traffic accidents, particularly on winding country roads.
But itís not just safety to consider, itís also about saving money.
Itís a proven fact that incorrectly inflated tyres wear out unevenly, and as a result require replacing more regularly. Itís also true that if your tyres are under-inflated your car will use more fuel, and as a result emit more CO2. Thatís lose-lose both ways, and who wants that?
For these reasons, the Department for Transport and leading tyre manufacturer Continental recommend that you undertake monthly tyre pressure checks, even for cars fitted with TPMSs.
So why do heavy loads change the way your car handles?
Itís a good question. Letís say that your tyres were correctly inflated to the standard ďun-ladenĒ pressure values before you set off on your holiday (because you regularly check them, right?). By the time youíve added a few hundred extra kilograms of luggage, bikes, equipment, and general stuff, as well perhaps as the dogs, a couple of adults, and some kids, youíll be looking at around an additional half tonne of additional weight - perhaps even more.
That extra weight changes things dramatically for your tyres. Why? Because the rubber compounds are slightly flexible, the tyres expand and Ė instead of being correctly inflated Ė they start behaving as if theyíre under-inflated.
Remember, under-inflated tyres affect your carís handling, as well as its ability to stop quickly in an emergency. Youíll also waste fuel, so itís vital to adjust your tyres to the ďladenĒ weight pressure before you set off on holiday. The money you save on fuel is better served being spent on your holiday.
Where can you find tyre pressure values?
Look up the tyre pressure values in your carís user manual. Theyíre often also printed on the inside of your fuel cap, and inside the driverís door. Youíll typically find two figures; oneís for normal Ďun-ladení use, and the other Ė a higher figure Ė is for when your car is laden.
How do you adjust tyres to the laden pressure?
Typically, the easiest place to top up your tyre pressures is at your local service station, and this can be done for a relatively small charge. Simply remove the valve dust cover from each tyre, and attach the air hose. The hose also measures tyre pressure. Then, set the correct tyre pressure according to the vehicle manufacturerís advice. Either top up or release air until the pressures are correct for all wheels at the laden weight.
If youíre not sure youíve got it right, leading tyre brand Continentalís advice is ďdonít leave it to chance, seek professional adviceĒ.
