First and foremost, it is a matter of safety. However, it will also save you money in the long run. Taking care of your tyres is not just about switching between the winter and the summer set or checking inflation pressure from time to time. The presence of a TPMS in the equipment of your vehicle is a handy help in everyday life but does not exempt you from checking the tyres constantly, at least once a month and according to load.
FIRST OF ALL, WEAR
Correctly inflated tyres ensure maximum vehicle control at all times. They are protected from premature wear (and therefore unexpected costs) and the risk of punctures or air leakage is reduced. It is worth remembering that the correct pressure is indicated by the manufacturer in the owner's handbook. Ignore advice from non-experts and unsubstantiated theories (such as higher pressure improves fuel efficiency). The right pressure is the one shown in the handbook and must be respected.
ROTATE FRONT AND REAR
Looking after your tyres also means swapping them every 15-20 thousand kilometres from the drive to the dead axle and vice versa. Some still say to involve the spare tyre in the rotation but it is actually a mistake. Of course, you need to make sure that the spare is always ready for use in a possible emergency. Tyre rotation obviously extends their working life and, when the time comes, you can change the entire set. This will ensure that the performance of your car remains balanced. Rotation is absolutely mandatory for all-season tyres which are not changed seasonally. It is also the opportunity for an accurate inspection. Include the valves which are essential for proper operation in the check.
STORE THEM PROPERLY
The importance of storing tyres once they have been removed from the vehicle is often underestimated. Specialist tyre fitters have areas equipped for this purpose, but you can also store them in your own garage or storage space. Once again, there are some precautions not to be overlooked for the care and integrity of your tyres. The signs of poor storage are very visible and are usually recognisable as surface cracks. In any case, after having thoroughly cleaned the surfaces removing any oily residues, petrol or other, store the tyres in a dry, ventilated and cool place, protected from sunlight and from the elements. The location must be away from chemicals, solvents or hydrocarbons, sources of heat, incandescent bodies or materials which could cause sparks and/or electrical discharges or sources of ozone (transformers, electric motors, welding equipment and so forth). Again, it may all seem obvious, but it is not. Tyres should be stacked carefully on their sides, without placing weights on top of the stack as this could cause deformation, especially if the tyres are stored without wheel rims. Finally, an elementary but useful trick: mark your tyres with a chalk or any other erasable material, indicating whether it was on the right or left or on the front or rear axle. In this way, you can easily recognize them when they need to be fitted again and have all the information you need for correct rotation.
