When Will You Need New Tyres? How Long Do Tyres Last?

Because your car’s tyres are the sole link between the vehicle and the road, keeping them in good repair should be a top priority. Tyres deteriorate over time and lose their capacity to retain optimum road grip. If you leave them on for too long, the tyres may blow out, resulting in an accident.

How long do tyres last is a question that many automobile owners want to know the answer to? Is there a limit on how many kilometres or years they can operate? We’ll go over this, as well as how to extend the life of your tyres, further down.

When it comes to tyres, how long do they last?

The lifespan of a tyre may be measured in two ways: time and wear. Tyres, on the other hand, have an expiration date — kind of. Every new tyre has had a 12-digit identifier called the tyre identification number (TIN) or Department of Transportation (DOT) code imprinted on the sidewall since 2000.

The last four digits of this code are always numerical and represent the tyre’s production week and year. A tyre with the final four numbers “2620” was made in the 26th week of 2020, for example.

According to most tyre manufacturers, a tyre’s usable life is around ten years. However, some experts advise having them evaluated every six years and contemplating replacement.

The age of a tyre is important because the rubber begins to dry up over time, causing it to harden and lose traction. Old tyres’ tread can also become brittle and break from the tyre itself, resulting in a catastrophic blowout.

The depth of the valley between two tread blocks is used to estimate tyre tread depth, which is used to determine wear. Most tyres are safe up to 1.6 mm, but above 3.2 mm, some winter and all-terrain tyres must be replaced.

How long are my tyres going to last?

Predicting how many kilometres a tyre will survive is more difficult since it depends on the tyre type, driving circumstances, and driving style. However, the guarantee on a tyre can give you a decent sense of how far it should go.

Tyre warranties differ, and some tyres have no warranty at all. Those with a kilometre warranty usually have a range of 40,000 to 130,000 kilometres. If the tread depth on your tyre falls below the manufacturer’s guideline before the warranty period ends, you’ll most likely be given a prorated credit toward a replacement tyre.

The treadwear rating is another factor to consider when estimating how many kilometres a tyre will endure. The treadwear rating, which runs from 60 to 620, is imprinted on the tyre’s sidewall. This grade represents how far a tyre travelled in comparison to other tyres during a 9,600-kilometer controlled test.

The reference standard for a treadwear rating is 100, which represents a normal tyre. A tyre with a treadwear rating of 200 will wear twice as fast as a standard tyre, while one with a value of 620 will wear 6.2 times as fast.

High-performance and summer tyres, in general, have the lowest lifespan because they employ softer rubber to improve grip. Performance and summer tyres, in many circumstances, do not come with a kilometre warranty. They only have fault guarantees in these cases.

All-season tyres, on the other hand, have the longest tread life since they’re more concerned with ride comfort and traction in the rain and snow than with high-speed grip. These are the tyres that are often found in the 130,000-kilometer warranty range.

What effects do driving style and weather have on tyre life?

Your vehicle’s tyres are its sole link to the road, and how they interact with it may have a significant influence on its longevity.

Aggressive driving can increase the amount of heat and stress that the rubber is exposed to, causing early tire wear.

Here are some examples of aggressive driving:

  • At high speeds, there is a lot of hard cornering
  • Excessive acceleration
  • Braking forcefully
  • Driving at a high rate

However, the problem isn’t always caused by poor driving practices. It might be the road conditions you’re travelling on in certain circumstances.

Snow and ice on the road are common in Canada, and they can cause your automobile tires to slip and slide. While sliding over snow and ice will not shorten the life of a tyre, if a slipping tyre suddenly grabs concrete, it places tension and heat on the tire, which can cause excessive tire wear.

How can I make my tyres last longer?

Tyres are one of the most costly maintenance items you can buy for your car, so you want to be sure you’re getting your money’s worth. This is possible with appropriate tyre care and a few other pointers, which we’ll go over below.

Change the way you drive

If you’re finding that your tyres are wearing out rapidly, take a look at your driving style. Do you ever find yourself accelerating or braking too quickly, or turning like a Formula One driver? Or perhaps you’re speeding down the highway.

Whatever the issue, changing your driving technique is a simple and effective strategy to extend the life of your tyres.

Choose the correct tyres

It’s fairly unusual for automobile owners to bring their tyre size to a tyre store and just ask for the cheapest tyres they can find. While this is occasionally acceptable, certain vehicles necessitate the use of specialized tires.

If you buy a conventional passenger vehicle tyre, you may put too much stress on it, causing it to wear out prematurely or fail.

The same may be said regarding the driving conditions. We have harsh, snowy winters in Canada, and snow tyres are almost a need to get through them.

Manufacturers tailor their rubber compositions to remain soft in low conditions, and winter tyres feature unique tread patterns to reduce wheel slippage, which can cause excessive wear. When all-season or summer tyres are exposed to sub-zero conditions, their rubber hardens and becomes brittle, causing excessive wear and even tread chipping.

So, when winter approaches, swap from your all-season or summer tyres to some winter shoes.

Rotate your tyres regularly

Tyre rotations are one of the most routine maintenance tasks, and they are crucial to their longevity. A tyre rotation entails lifting the car and removing all four wheels, then repositioning each wheel on the vehicle.

There are five different rotation patterns to choose from. Some designs are designed to fit certain tire types, while others are designed to compensate for uneven tire wear.

Plan to rotate your tyres every six months or 12,000 kilometres, whichever comes first. Some vehicles demand more regular rotations than others, so verify the manufacturer’s official guidelines in your vehicle‘s owner’s handbook.

Every six months, get your alignment checked

Your vehicle’s chassis must bend and move to maintain the tyre tread on the surface. All of this flexing and moving leads the chassis components to lose their baseline orientation over time, resulting in the tyres resting at an unnatural angle on the road. This is known as out of alignment, and it can lead to excessive tyre wear.

You may avoid this by having your vehicle’s alignment examined every six months and, if necessary, having it corrected. Four-wheel alignments may be costly, ranging from $60 to $100, although some businesses charge a greater rate for lifetime alignments.

Regularly check your tyre pressure

Your tyre’s air pressure has an immediate influence on how they wear. When there is insufficient pressure, the middle part sags, forcing all of the car’s weight to fall on the outer edges, resulting in excessive wear on the outer edges. Too much air pressure causes the centre area of the tyre to bulge, producing excessive wear in the tread’s midsection.

Check and adjust your car’s tyre pressure once a week to avoid this. Always check and adjust the pressure before driving, since the heat from the vehicle can cause the pressure in the tyre to rise, giving a misleading reading.

Also, set the pressure according to the manufacturer’s recommendations, which may be found in the owner’s handbook or on the tyre placard in the driver’s door jamb. Never set the tyre pressure to the tyre’s maximum pressure rating, since this will almost always be far too high.
