Without the proper performance from your tyres, you will not be safe while driving. Your tyres are what keeps you safe when you drive, so it is of utmost importance that you purchase high quality tyres and that you maintain them while you drive. It is important to realize that tyres are made to wear out, the speed of wear is partly dependent of how well you maintain them, how you rotate them, the quality of your tyres, your driving habits and car load.
Tyres of higher quality tend to be more wear resistant and will last longer, they also tend to have a lower rolling resistance, which makes the tyres wear out slower and also consume less petrol. When you wear out the tyres, the grooves in the tread will diminish and when the tread depth reaches 4 mm, it is time to purchase a new set of tyres. You will need to make sure that all the tyres reach the 4 mm mark at the same time by rotating the tyres to even out any increased wear between the rear and the front axel.
Careful driving also tends to produce lower tyre wear, while heavy load will wear out the tyres faster. When you have a hybrid or an electrical car, those tyres will wear out faster due to the extra weight of the battery packs. It is important to purchase wear resistance tyres in this case and make sure to rotate them more frequent than you would with a normal car. If you change between winter and summer tyres this is a natural point to rotate the tyres, unless you need to do it more frequently.
The tyre maintenance that you will need to do to ensure that you can drive safely is to check the tyres for any damages caused by hitting curbs, or potholes or other possible defects. If you notice any cuts or cracks in the tyre, you should seek advice from a tyre service station to see if the tyre can be repaired. You need also make sure that you have the correct inflation pressure in the tyre. If you have too low pressure in the tyres, the tyre wear will increase and you will wear out your tyres faster. Also the fuel consumption will increase, so that it is more costly to drive. So check the tyre pressure to make sure that you drive safely and efficiently.
