Every automobile has tires and one of the main reasons for accidents is often because of driving on old and worn out tires. Here is some tire help and basic info.


Since every car has tires, it makes a lot of sense for any driver or aspiring driver to know about tires. There is a lot to know about them and you’ll probably surprised how much you didn't know by the time you finish reading this!

Tire Life

First off, it is very important to understand that tires typically have a life of 50,000 miles/4 years, whichever comes first. Most people know about the number of miles a tire is designed to run, but equally important is the age of the tire. Even if the tire has never been run at all, 4 years is it, the tire is no good anymore. Some higher quality tires last longer, but even for them it is almost never beyond 6 years from the date of manufacture.

That is why every tire has a 4 digit code written on it depicting the manufacturing week, like 0508. The first two, “05″ indicate the week of the year which is represented by the following two digits. In the “0508″ case, the tire was made in the 5th week of 2008. That would mean the tire is good to run until around the 5th week of 2012.

So before buying a new set of tires and whenever buying a used car, notice this, because you don’t want to find out your tires expire 6 months after you bought them! And driving on expired tires is extremely dangerous and lessens the vehicle’s grip tremendously so much that you actually feel the loss while driving at high speeds, on slick roads and while cornering.


Secondly, comes the traction rating. On every tire, you will find “Traction” written, along with an alphabet; either AA, A, B or C. AA is the best while C is worst. AA basically means the tire is rated to provide excellent traction and will provide a “sticky” grip, or otherwise expressed as “hugs the road”. C is the worst and should be avoided however and whenever possible.

You will also find tires with M/S or M+S written on them, indicating these tires are for mud and snow.

Speed and Weight Codes

You will also find every tire with another certain code in the format of a two or three digit number followed by a letter, such as 85V. The number represents the load which the tire is designed for; 85 for example is for 515 kg (1135 lbs), 100 is for 800kg (1764 lbs). The letter represents what speed the tire is designed for. It starts at A1, which is meant for 5 kmph (3mph) and goes on to Z which is for over 300 kmph (over 186mph). Most passenger cars will have either W (168 mph), V (149 mph) or H (130 mph).

There is a lot more to learn about tires, but I have made this article concise so that the basics and main important points are highlighted.

Hope this helps, happy driving!
