According to the New York Times, in the 1960s and 1970s, the typical car reached its end of life around 100,000 miles (160,000 km). Due in part to manufacturing improvements, such as tighter tolerances and better anti-corrosion coatings, in 2012 the typical car was estimated to last for 200,000 miles (320,000 km) [ 4 ] with the average car in ...
This heat compromises the internal structure of the tire which can lead to a blowout. When a tire is over-inflated, it wears the tread down faster, and becomes more prone to catching nails or screws in the tire. The best way to check tire maintenance is to check the air pressure, because that will lead you to whatever problem your tire might have.
The wet grip index (WGI) is calculated from the results of two tests specified in the regulations. The first test measures the maximum achievable average deceleration of a vehicle as it slows from 85 ± 2 km/h (52.8 mph) to 20 ± 2 km/h (12.4 mph). The second test (the "skid trailer" test) is usually performed using a tow vehicle and trailer.
Car and tire manufacturers may recommend tire rotation frequency and pattern, typically every 5,000 mi (≈8,000 km) to 8,000 mi (≈13,000 km) depending on the tire manufacturer and vehicle make [3] to ensure even tire wear.

Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency as approximately 5–15% of the fuel consumed by a typical gas car may be used to overcome rolling resistance.

Less commonly used in the US and Europe (but often in Japan for example) is a notation that indicates the full tire diameter instead of the aspect ratio of the side-wall height. To take the same example, a 16-inch rim would have a diameter of 406 mm. Adding twice the tire height (2×107 mm) makes a total 620 mm tire diameter.
