Optimal depths A new car tyre begins life with approximately 8-9mm of tread depth. Legally, you can drive on them until they reach a minimum depth of the tread of 1.6 mm, across 75% of the tyre’s width and all around its circumference.
What is the average tread depth of a tire?
New tires have an average tread depth of 8 to 9 millimeters (10/32 to 11/32 inches). As you drive, the tread will wear down. A tire with a tread depth below 1.6 millimeters (2/32 inches) lacks grip. Braking distance and vehicle control are impaired. These tires are not safe for driving and must be replaced.
How deep should new tyres be?
Legal requirements for tread depth New tyres are manufactured with around 8mm of tread depth, but this wears away over time, which compromises the car’s road handling, ability to cope in wet conditions, road grip and safety.
How much tread is on a new tyre?
All vehicle owners and drivers should make a point of inspecting the tyres on their vehicles regularly, ensuring that they have adequate tread, are correctly inflated and are completely fit for purpose. How much tread is on a brand new tyre? On a new tyre, tread depth is about 8mm.
Is 2 mm tyre tread legal?
Tyre tread depth has to be above 1.6mm to be legal. This must be the case for the middle three quarters of the tyre. What is the legal limit for tyres to pass MOT? The legal tyre tread depth in the UK is above 1.6mm in the middle three quarters of the tyre. How long does the average tyre last?
Do tires go bad with age?
How long can a tire last? Most auto manufacturers recommend replacing tires over six years old regardless of tread depth. Some tire manufacturers like Michelin and Continental give a 10-year limit. As rubber compounds age, they deteriorate and become weaker like other rubber and plastic components on your car.
Are old tires dangerous?
Old tires are dangerous, regardless of tread depth. While there’s no federally sanctioned safety guidance on when a tire is too old to be safe, many carmakers recommend replacement at six years from the date of manufacture. Old tires have been the culprit in fatal accidents. Here are just two examples:
Is it safe to replace a tire that’s 6 years old?
A tire that’s 6 years old or older isn’t safe and should be replaced, regardless of wear. People usually rely on a tire’s tread depth to determine when to replace it. But tire age is critical, too.
How long is a tire safe to use?
The National Highway Traffic Safety Administration (NHTSA) and official manufacturers suggest a tire is only 100% safe to use until it turns 5-6 years old. However, some admit that a tire can be operable up to 10 years if you check it for issues annually after the 5th year.
When do tires age?
That’s when the real ageing process starts, when it’s exposed to high speeds, sudden braking, difference surfaces, extreme temperatures, and heavy loads. And mind you, tires also degrade even when the vehicle is not used. So, what does Michelin recommend?
How long should tires last miles?
50,000 to 60,000 miles
Your tires should last 50,000 to 60,000 miles on average. But that really depends on the manufacturer. Some manufacturers build their tires to last up to 80,000 miles, while some design their tires to last as little as 30,000 miles. You can see how many miles to expect out of a tire by checking its treadwear rating.
How many miles do new tires last?
Though we would expect at least 50,000 miles from original-equipment new tires (and quality replacement tires), the reality can be quite different. Owners of late-model Honda CR-Vs have complained to us, for example, that they had to replace all four new tires around 20,000 miles.
How long do tyres last?
In 5 years, your tyres will probably have been run over many different surfaces and perhaps have suffered shocks. After 5 years of use, have them checked by a professional at least once a year. This will ensure that they have not been damaged prematurely and that they do not endanger you or your passengers. Tyre DOT: how to tell tyre age?
How long do scrapped tires last?
For what it’s worth, the USTMA did a review of several thousand recently scrapped tires and found that most were three to four years old. There was no way of telling how many miles were on those tires, but it’s easy enough to multiply four years by 15,000 miles annually to confirm the rough approximation of tire durability.
How often should you rotate your car’s tires?
As a general rule, we recommend every 5,000-7,000 miles, but it depends on numerous factors, including your car’s alignment. You can read more on The Drive ’s guide for How To Rotate Car Tires. How Often Does Your Car Need an Alignment?
How much difference in tire size is acceptable?
As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of your existing tires’ diameter — assuming your current tires are what your owner’s manual recommends.
What is a tire size calculator?
What sets this tire size calculator apart from the available alternatives is that it also computes the difference in pace at which the vehicle can reach a given speed between two different sets of tires. You may also like to try our online power to weight ratio calculator to determine the power-to-weight ratio of any vehicle.
Do you go up a width when replacing OEM tires?
I’ve routinely gone up a width (and usually in quality – performance-wise) when I replace OEM tires. Most vehicles can accommodate that extra quarter-inch on each side and often have optional tire sizes one or two widths up from basic stock.
What are the differences between tires from each manufacturer?
Tires from each manufacturer have small variances in diameter and width from one another. In most cases the calculated dimensions will be very close, but this is why we provide a list of tires that are manufactured in each size. After calculating, you can select individual tires to check the actual manufacturer specs for that tire.
What should I consider when buying a new wheel & tire?
Also, you should be sure to consider the downsides of larger, heavier wheels and tires. Your vehicle’s ride quality (and susceptibility to wheel or tire damage by potholes) as well as braking distances may be negatively impacted, potentially severely so, depending on how extreme you get with your wheel-and-tire size.
How much tread is legal?
1.6mm
Use Tread Wear Indicator (TWI) The legal limit of 1.6mm is reached when the tyre is worn to the level of the tread wear indicators in the main groove — as soon as this happens, the tyre should be replaced.
How many miles can you wear with 1 mm of tyres?
approximately 1,000-4,000 miles
How Many Miles Per 1mm of Tyre Tread? On average, you should get approximately 1,000-4,000 miles out of one millimetre of tyre tread, but everything from your driving style to the road and weather conditions can have an effect on how fast it’ll wear.
How many miles per mm of tyre tread?
The legal limit of tire tread is 1.6mm, and when it’s getting low, many vehicle owners will start to hold questions like ‘How many miles per mm of tyre tread.’ It is normal, and you have a right to know so that you go for a replacement at the right time.
How many miles can a car go on premium tires?
Besides, we all have varying driving habits, meaning that I can make many stopovers and fast cornering while you don’t. Approximately 1mm on premium tires means a lot as you can go up 10000 miles. But, with budget tires, the mileage won’t exceed 10000; unless your vehicle spends a lot of time in parking.
Can You Drive on tyres with less than 2mm?
Don’t be tempted to risk driving on tyres with less than 2mm, as road grip will be affected. This is particularly the case in wet driving conditions, compromising your own and your passengers’ safety. Cracked, worn and damaged tyres need to be replaced as a matter of urgency – never be tempted to drive on unsafe tyres.
How many miles should a car tyre last?
Miles wise, you should be able to get at least 20,000 miles out of your front tyres and 40,000 for your back tyres. However, this depends on a few factors, chiefly: The quality of the tyre itself. The road conditions it’s used on.
How long do rear tyres last?
Under normal driving conditions, you should get a minimum of 20,000 miles out of front tyres on a front-wheel-drive car. For rear tyres, it can be double that – around 40,000 miles. We recommend moving worn rear tyres to the front when the front ones wear out. How does wear affect tyre lifespan?
How many miles do tires last?

Is 4mm tyre ok?
Optimal depths Legally, you can drive on them until they reach a minimum depth of the tread of 1.6 mm, across 75% of the tyre’s width and all around its circumference. However, we strongly recommend that you replace your summer and all-season tyres when they reach 3mm and your winter tyres at 4mm.
Should tyres be 3mm or 4mm?
Legally it’s been said 1.6mm, [but] some people are starting to say 3mm, 4mm, which is almost half of the tread depth, which is an absolute waste for the economy. If you remove the tyre at 3mm instead of 1.6mm it means you have one tyre per car every two years to be added – which is enormous.
Are 4 mm tires safe?
This should be covered by law. In my country the legal safety limit for winter tires is 3 mm, and for regular tires – 1.6 mm. So 4 mm is not unsafe, but you should start looking for tires. If the road is perfectly dry, you would get the best grip with no tread at all – en.wikipedia.org/wiki/Racing_slick .
Are 4 mm tires good for snow?
Tires with a 4 mm tread depth fall short of even half the performance of the new winter tires. You can easily guess how well the tires with a minimum allowed tread depth of 1.6 mm will perform — they simply have nothing to bite into snow with.
Is 4 mm tread safe?
So 4 mm is not unsafe, but you should start looking for tires. If the road is perfectly dry, you would get the best grip with no tread at all – en.wikipedia.org/wiki/Racing_slick .

Is 2mm tyre tread OK?
Is 2 mm tyre tread legal? Tyre tread depth has to be above 1.6mm to be legal.
Should you change a tyre if the tread wears to 3mm?
Last week Michelin courted controversy by announcing that changing a tyre when the tread wears to a 3mm depth is essentially wrong, and that drivers should keep using their tyres right down to the 1.6mm legal limit.
How much tire tread is safe?
Tires are no longer considered safe once the tread depth has reached 2/32″. This is the point at which they will not pass an inspection and require replacement. It is often suggested that you replace your tires at 4/32″ or 3/32″ to improve stopping distance on wet roads and help reduce the chance of hydroplaning.
Should I check my tyre tread depth?
Here’s everything you need to know about checking your tyre tread depth. Your tyre’s tread is designed to keep the tyre in contact with the road. So, as your tyre wears, its ability to grip the road decreases, meaning longer stopping distances and a higher risk of aquaplaning.
Should tyres be 1.6mm or 1mm?
Exactly. Actually we encourage [this]. We say we should use the tyre to 1.6mm which is the legal tread indicator and that’s true for wet performance, wet conditions, snow conditions. Good quality tyres can be used up to the tread wear indicator at 1.6mm, in good safety condtions. BD: So why 1.6mm? Why not 1mm or 2mm?
Why 28mm tires?
A 28mm tyre will have less rolling resistance and therefore be faster, while still offering good grip and comfort. The main downside of a 28mm tyre is that they can be more susceptible to punctures, but this is easily alleviated by running a higher pressure.
Are 28mm tyres better?
The 28mm versions of the best-rolling tyres will be faster still, and over the next few years they’ll fit more and more new bikes as manufacturers expand their ranges of bikes with disc brakes. Riders whose bikes will take them report that the 28mm versions of the fastest tyres really are another step up in comfort.
Is 28mm the new 25?
This is why, a couple of years ago, road bikes started appearing in shops with stock tires measuring 25mm instead of 23mm. Now, thanks to the wanderlust that’s taking more of us off-pavement, and our collective growing desire to ride longer and more comfortably in more conditions, 28 is starting to become the new 25.
Is it time to switch to 25mm tyres?
For many years 23mm wide tyres were the default choice for road bikes. Many racers used 21s or even narrower. In the last few years 25mm tyres have become the most popular option for both professional and amateur riders, and some riders have gone wider still. If you’ve not yet made the switch, it’s about time you did. Here’s why.
What are the benefits of a wider tyre?
With a larger chamber of air between you and the road, a wider tyre allows you to drop the pressure without running the risk of a pinch flat (where the inner tube gets punctured as a result of being sandwiched between the wheel rim and the ground). The lower pressure increases the amount of cushioning you get from the road, improving your comfort.
Is 7mm tire tread good?
Legal minimum tread depth is 1.6mm. Safe driving in wet and snowy weather conditions is affected by the tread depth, the pattern design and the rubber compound of the tread of your tyres. On wet and snow covered roads braking performance will progressively decline with lower tread depths. Check your tyres regularly.
What is a good tread depth for a new tire?
Tread is the rubber on the tire that touches the road. New tires have an average tread depth of 8 to 9 millimeters (10/32 to 11/32 inches). As you drive, the tread will wear down. A tire with a tread depth below 1.6 millimeters (2/32 inches) lacks grip. Braking distance and vehicle control are impaired.
Are 6mm tyres better than 7mm?
It’s a complicated science, allied to the fact that a new tyre with 6mm will roll more easily, and thus more economically, than one with 7mm. You’re not wrong but it’s further complicated by big variations in the void ratio – so tyres designed for maximum wet grip will squirm and wear more than tyres designed for maximum dry grip.
What is the difference between 7/32 and 10/32 tyres?
Basically, the term 7/32 tires include two meanings. The first is that it’s a used tyre. The other indicates the new level or status of the tires. In this case, tire tread depth 7 32 compared to 10/32, an original tread depth, is quite good and comparative. We would like to mention the depth in other specifications for easier understanding.
How do I know if my tire treads are good?
Tread Depth Gauge – Another very simple way to test the tire treads is by using the tread depth gauge. You can consider buying a tread depth gauge online or find it at the auto parts store near you. The models may be different but they’re generally inexpensive and work in the same way.
Is 5mm tyre tread OK?
If the red is visible the tyre tread is below 1.6mm. This means the tyre is 100% worn and should be replaced urgently. If the orange is visible, the tyre tread is 3mm which is the recommended minimum. If the green is visible, the tyre tread is above is 5mm and is safe to drive.
How deep should tyres be?
Once the surface of the tread rubber is level with these raised areas, the tyre tread depth is approaching the legal limit of 1.6mm and you should have your tyres checked and replaced . If you’re unsure whether your tyre tread depths are at a safe level, you can use a handy tyre tread depth gauge to help.

How much tread left on a new tyre?
All tyres are differ. But most new tires come with 7-12 mm tread new. So u about half way to 30% left. I say around 6 months with normal driving on a medium compound. Or standard road tire! Sport tires are softer!!!!!!!!!!!!!!!!!!!!!!!!!
How long do budget tires last?
When we consider all the variables, the shortest distance the 3mm will last ranges between 10000-20000 miles. This is the minimum mile coverage, meaning that it can exceed the specifications. Try to replace the tires as much as possible before it reaches 1.6mm. Do budget tires wear faster?
Is 2.5 mm tyre tread OK?

Are 3mm tyres better than 1.6mm?
Independent research by the Motoring Industry Research Association (MIRA) has shown that tyres with 3mm of tread have an average 25% better performance than those at 1.6mm – which represents an extra 8 metres of stopping distance in wet conditions! The typical lifespan of a quality tyre is between three and five years.
Is 1mm tread better than 1.6mm?
There are many tire manufacturers in the lab, state-of-the-art testing tracks, chemical formulas, and test driving to produce a premium tire quality. Therefore, 1mm tire tread is more valuable in a premium tire than 1.6mm in a budget option. The assembled knowledge to produce premium tires is expensive, giving the tires a robust design.
Why 37 inch tires?
Designed for traction, all-terrain tires in 37 inch fitments feature aggressive tread patterns with plenty of biting edges and high voids. They also feature reinforced sidewalls and aggressive shoulder blocks for traction and durability when you have to tackle sharp rocks and harsh terrains.
What is the difference between 35 and 37 inch tires?
The 35-inch tire sits between the 33″ and 37″ in terms of on-road and off-road rolling resistance. In contrast, putting all tire sizes together, the 37-inch tire has the lowest off-road rolling resistance, which allows for higher fuel economy when you are driving off-road. The bigger the tire size, the higher it is going to cost.
Do you need a lift to run a 37-inch tire?
With a 35-inch tire, a lift is compulsory. For proper ground clearance, you will need a lift of 2.5″ to switch safely. If you have a 37-inch tire installed, it means that you are a serious off-roader. You will need a lift of 3.5″ or more to run a 37-inch tire.
