Be sure to check your tire tread on a regular basis to find out whether a tire needs replacing. 
All passenger, light truck, and medium commercial tires have tread wear indicator bars molded into the tread and located at the bottom of the tread grooves in several locations around the tire. When the tire is worn to the point where any of the bars become visibly flush with the adjacent ribs it has reached the minimum legal tread depth (1,6 mm). We recommend to replace the tire well before the minimum level. If the tire tread is wearing out in only one or two places, it can mean that the tire is inflated wrongly.
Adequate tread depth is essential for good grip on wet roads as the tread pattern helps to remove water from the road surface. This is why driving with passenger tires of under 1,6 mm tread depth is both illegal and dangerous.

It is essential to check tire inflation pressure at least once a month using an accurate tire pressure gauge. Both under- and over-inflation can cause abnormal, excessive wear and tear, which in turn can lead to tire overheating, fuel overuse and even a tire blow-out. 

The inflation pressure indicated on the side of the tire is the maximum operating pressure, it's not necessarily the right inflation pressure for your vehicle.  Always use the inflation pressure recommended by the vehicle manufacturer which you will find in your owner's manual, posted on the edge of the driver's door, on a door post or on the inside of the glove box door.  And make sure you check the pressure while your tires are cold. Driving even one kilometer will cause your tire pressure to increase and so cause an inaccurate setting. Continuous loss of inflation pressure indicates a possible tire or wheel assembly problem and you should consult a professional tire dealership immediately.

Goodyear EMEA* favors Tire Pressure Monitoring Systems (TPMS), as they inform you in real time on the tire pressure level, and enables you to adjust it, which enhances safety, optimizes fuel efficiency, reduces CO2 emissions and lengthens the life of a tire.

In the effort to promote good practice ETRMA (The European Tyre and Rubber Manufacturers’ Association) has created basic guidelines and recommendations on tire service life tire handling and storage for tire dealers and basic tire safety and maintenance for consumers.
