SAO PAULO - What tires should be replaced, calibrated, balanced and aligned many many already know, but few know the meaning of the numbers printed on them. These numbers are essential for the driver to choose the right tire for the car.
You know what the code means 185/60 R14 82H of your tire? Idec (Department of Consumer Protection) help clarify what is behind these letters and numbers.
Cracking the code
The first number is the width of the tread - part of the tire that directly touches the ground - always in millimeters. Thus, the tire in question above is 185 millimeters wide.
The second number after the slash refers to the height of the profile in relation to the tread. In the example, the profile is 60% of the size of the tread, ie, 111 mm - 60% of 185 mm.
The "R14" indicates the wheel diameter in inches. The wheel of example, and has 14 inches or 355.6 millimeters in diameter, as one inch equals 25.4 mm. The number "82" is the load index. In this case, the tire holds up to 485 pounds. The letter comes next refers to the maximum speed that the tire support. In this case, the "H" indicates that it supports up to 210 km / h.
With an eye on specifications
According to coach Cesvi Brazil (Center of Experimentation and Road Safety), Felicio Felix, to keep an eye on the tire itself and the vehicle's manual. "It is strongly recommended that the technical specifications of the tires are maintained," believes.
In time to replace them, prefer to stick to the brand. Change, however, does not bring security risks, ensures Idec. "But whatever the manufacturer, the symbol of Inmetro (National Institute of Metrology, Standardization and Industrial Quality) is required," says the institute.
It is also recommended to escape the technique of scratching bald tires. "It's a very dangerous practice, because the tire can explode as the car in motion and cause a serious accident," says Felix.
