When it comes to buying tyres, most customers will undoubtedly have heard that there is an expiry date — from the date of manufacture — to look out for when making a purchase. However, how true is this notion? On the sidewalls of each tyre, there is a stamp known as the DOT Department of Transportation code, which includes a four-digit figure. This figure is the manufacture date. Should you find a tyre with a DOT code that has just three digits, the tyre is made before the year avoid these. Referring to our earlier example, this would mean they were made two years ago, around the end of September According to the United States Rubber Manufacturers Association RMA , there is currently no standard to determine the expiry date of tyres, as the damage done to each tyre is based on a number of factors like temperature, load, tyre pressure used, the velocity at which the vehicle is travelling and others. Be that as it may, the British Rubber Manufacturers Association BRMA does recommend that new tyres that have not been used for six years or more should not be fitted to vehicles, and that all tyres exceeding 10 years from the date of manufacture must be replaced or disposed of. Adding on to this, Michelin states that tyres are not like fruits that go bad if left untouched.

When you look on the sidewall of a tire, you will notice two prominent things: the brand name and size.
The latter will have a few formats but is simple to find. So, in this example, the tire is millimeters — 9. This is the height of the sidewall from wheel to tread relative to the width. In our example size, the tire will fit a inch wheel.

Tires are just about the most important part of your car. If they’re in bad shape, the car’s ability to accelerate, stop, and turn in all conditions is greatly compromised. Everybody knows to replace tires when the tread gets down to the wear bar, but what about when they get too old? The rubber in tires deteriorates over time due to UV and environmental exposure. The resulting “dry rot” leaves tire structure brittle and leads to sidewall damage and eventual failure.
This isn’t “Oh I’ll just fill it up and drive on it. As a precaution, the Department of Transportation recommends changing even new-looking tires once they hit 10 years old, and many manufacturers recommend swapping them out at six years old.
