One of our drivers encouraged me to get a fairly used tyre because it is more original to the new ones, and I should go for first grade, that I may be lucky to get the complete four even with rims, he also said a new tyre if it picks nail it's same thing with a fairly use one.

Informative

Great job. Thanks

Please what of the air pressure how do one know how many u will pump into the tyre? Cos is not stated on it.

Tyres expires 3 years after date of expiration or once the tyre as cover 80, 000km before the expiration date of the tyre.

Topiipii:

Tyres expire in 6 years from the date of manufacture, although I have read on several sites that it's 4 years in Nigeria. Whichever the case may be, you can calculate the expiry date based on the date of manufacture of the tyre.

The type of car determines the pressure of the tyre. Check d driver side door, you will see the tyre presssure.

So I just bought this tyre for 19k

Using the link above, I realized that the dot number is only 4 digits and not 11 like the link says...

Also, I'm seeing two sets of numbers that could look like expiry date!

Temperature and Traction rating for the tyre is A

With this tyre matta how come non of these major tyre manufacturers had come up with this. How come it's always third party sites?
Main while the issue of tyre expiry dates does not exist in the west ie the UK? They just check for the depth of your thread. Your tyres have markers have you seen urs?

tooman:
expiry date is not how far but it's about time of purchase.

So why do tyres not expire in the west?

How old is too old? The five year test
After five years or more in service, your tyres should be thoroughly inspected at least once per year. If the need arises, follow the recommendations of the vehicle manufacturer regarding replacing the original equipment tyres. As a precaution, if the tyres have not been replaced 10 years from their date of manufacture (see how to read a tyre sidewall), Michelin recommends replacing them with new tyres. Even if they appear to be in usable condition and have not worn down to the tread wear indicator.

Regularly checked tyres last longer
Check your tyre pressures monthly and before any long trip. At the same time check the tyre tread depths, and look for any signs of sidewall damage, or irregular wear. If in doubt, seek the advice of a trained tyre expert who will be able to tell you if the tyre is suitable for further use.

Six reasons to change your tyres
Below, we list six major reasons when you should seriously consider changing your tyres. In certain situations, a tyre can be repaired. However, the repair of Michelin tyres must be preceded by a careful examination of all areas of the tyre, inside and out, by a trained specialist. The removal of the tyre from the wheel is essential because internal damage is not visible while the tyre is fitted.
1. If you get a puncture
Modern tyres are very sturdy and can cope with most things. Punctures, though, can and do still happen. A tyre specialist should check your tyre after a puncture to decide whether it can be repaired.
Safety procedures when you have a puncture while on the move:
Always consider your safety and that of your passengers, pull off the road in a safe place
Put on the parking brake
Switch off the engine and put the car in a low gear (or in Park on automatics)
Switch on your hazard warning lights
Wear a yellow high-visibility vest
Place a warning triangle at the side of the road 100m behind the car
Your safety comes first - always! Helpful tips for changing a punctured wheel
DO NOT attempt to change a wheel if it risks the safety of you or your passengers.
Carry a pair of sturdy gloves
Carry a bin bag in your boot, in case the tyre you're removing is covered in mud!
Carry a sturdy board to place your jack on in case the ground is soft, to avoid the jack sinking in.
Where necessary, use a light machine oil on the wheel nut threads to help their removal.
Check the inflation pressure of the spare tyre before fitting. If this is not possible, once fitted drive carefully at low speed until it can be checked.
Visit the nearest service station and inflate the tyre correctly.
Badly tightened wheel nuts risk damage to the brake discs or wheel mounting system
Use a torque wrench to make sure you tighten the nuts correctly with the correct torque.
If you don't have a torque wrench get a tyre specialist to check them as soon as possible. This will ensure the correct torque has been applied.

Correctly tightened wheelnuts will also make it easy to remove them.
2. When your tyres worn down to the legal limit of wear
It’s a good idea to check your tyres regularly for tyre wear. But how? Here’s a simple way to tell if your tyres are worn out.

Legal limit

A Michelin man figure on the shoulder of a Michelin tyre shows the location of the tread wear indicators situated in each of the main grooves of the tread. These indicators are small raised areas at the bottom of the grooves of the tread pattern.

If the surface of the tread rubber is level with these raised areas, the tyre tread depth is most likely very close to the legal limit of 1.6 mm. Or below it! Michelin strongly recommends that you consider changing your tyres before this limit is reached. They may no longer provide sufficient safety and you could be breaking the law.

Even if the remaining tread depth is greater than 1.6 mm, you should adapt your speed and driving style to the external conditions, particularly on wet roads.


Winter tread wear indicators at 4 mm (only in some European countries)

The intermediary tread wear indicator indicates a remaining tread depth of 4 mm. Thanks to MICHELIN 3D sipes on the full tread depth , the tyre maintains its winter performance below this indicator.

3. If your tyre shows signs of aging
Tyres have no predictable life. It does’t matter when the tyres were made. Tyres age even when not used, or if only used occasionally. There are many factors that will affect the life of the tyre such as temperature, maintenance, conditions of storage and use, load, speed, pressure as well as driving style. These will have a great impact on the length of service life you can expect from your tyres.
Pay regular attention to your tyres
For these reasons, Michelin recommends that all drivers pay regular attention to the external appearance of their tyres for clear signs of aging or fatigue. This can include cracking of the rubber or deformation, etc. Excessive aging of tyres may lead to loss of grip. Michelin also recommends all tyres, including the spare, are inspected regularly by a tyre specialist. They can tell you whether your tyres should continue in service.
How old is too old? The five year test
After five years or more in service, your tyres should be thoroughly inspected at least once per year. If the need arises, follow the recommendations of the vehicle manufacturer regarding replacing the original equipment tyres. As a precaution, if the tyres have not been replaced 10 years from their date of manufacture (see how to read a tyre sidewall), Michelin recommends replacing them with new tyres. Even if they appear to be in usable condition and have not worn down to the tread wear indicator.

Damaged tyre

4. If your tyre is damaged
Your tyre can be seriously damaged if it impacts any solid object on the road, like a kerb, pothole, or sharp object. Any visible perforation, cut or deformation must be checked thoroughly by a tyre professional. Only they can tell you whether the tyre can be repaired or has to be changed. Never use damaged tyres or tyres that have run flat or at very low pressures unless they have been thoroughly examined internally and externally by a tyre professional. Inspection by a professional is absolutely necessary because internal damage is not visible while the tyre is mounted; only then can a decision be made as to whether the tyre can be out back into service.
Leave it to the experts
A tyre specialist will tell you if your tyre can be repaired after damage has occurred.
5. If you identify abnormal wear
Abnormal uneven tyre wear - in patches, in the centre, at the edges - may indicate a mechanical problem like improper wheel alignment, or a problem with wheel balance, suspension or transmission. It could also be that you're driving with the wrong tyre pressure. If you notice abnormal wear, contact your tyre specialist.

To prevent uneven wear, have your wheels aligned and balanced by a tyre specialist. This will also extend tread life and give you a smoother ride. Another way to keep your tyre wear even is to regularly rotate your wheel positions.
Common causes of abnormal tyre wear:
Wear on one shoulder: suspension misalignment.
Wear on both shoulders: under-inflated tyre.
Wear along the tyre's centre: over inflation.
6. If they’re not suited to your vehicle
For best all-around performance, the same type of tyre should be used in all four wheel positions. Tyres of different sizes, constructions, and stages of wear may affect vehicle handling and stability.

In addition, there may be specific recommendations by vehicle or tyre manufacturers which may apply to your vehicle. These should be followed, please check your vehicle handbook for details.
Never mix radial and non-radial tyres
Do not mix radial and non-radial (i.e. cross-ply or bias-belted) tyres on a vehicle. If mixing tyres is unavoidable, never mix radial and non-radial tyres on the same axle. If two radial and two non-radial tyres are installed on a vehicle, the two radials must be installed on the rear axle and the two non-radials on the front axle.

There are many ways to find the proper tyres for your vehicle. If you're not sure what tyres are best suited to your vehicle, use our tyre selector.
What does the law say?
REGULATION 25: This Regulation is concerned with the tyre's load index and speed ratings. It specifically deals with items such as the tyres fitted to Goods Vehicles, Buses and Trailers and for which a Ministry Plating Certificate must have been issued, and a Ministry Plate attached to the vehicle. Amongst other vehicle information the Plate, which must be securely attached to the vehicle in a conspicuous location, gives the maximum axle and gross vehicle operating weights. The Regulation requires that the tyres fitted to the vehicle are not only capable of supporting the maximum permitted load on each axle but of doing so at the vehicle's maximum legal speed. In defining 'load-capacity index' and 'speed category' the Regulation makes reference to UN ECE Regulations 30 and 54 and to the European Union Directive 92/23/EEC.

REGULATION 26: Deals with the mixing of tyres of differing structures. The regulation defines three types of tyre structure, diagonal ply (Crossply), bias-belted and radial. No vehicle shall be fitted with tyres of differing structure on the same axle. For cars and vans (even with twinned rear axle), the following are the LEGAL tyre combinations. Mixing of a temporary spare tyre on a car is allowed, provided it is not driven at a speed exceeding 50mph.

Front Rear
Diagonal ply (Crossply) Diagonal ply (Crossply)
Bias belted Bias belted
Radial Radial
Diagonal ply (Crossply) Bias belted
Bias belted Radial
Diagonal ply (Crossply) Radial
REGULATION 27: Deals with the condition and maintenance of tyres. It specifies when a tyre should not be used on the road due to for example: it not being suitable for the use to which the vehicle is being put, or issues relating to its condition or maintenance, such as inappropriate tyre pressures, cuts, bulges or tyre damage. It also allows the use of run flat tyres when in a deflated state provided the tyre and wheel are so constructed to be fit for the use to which the vehicle is being put. This Regulation also specifies that the grooves of the tread pattern of every tyre fitted to cars and light vans shall be of a depth of at least 1.6mm throughout a continuous band comprising the central three quarters of the breadth of tread round the entire circumference of the tyre.
In accordance with these rules, look under the heading 'Tyre selector' for the alternatives offered by MICHELIN for each vehicle model.

You have yourself a rotational tire and you need to pay attention to proper mounting. This is exactly what killed the Senator.

ah Baba I site you Oo
its amazing how we Nigerians in Nigeria do not pay attention to these things,do U know some people do not know the thread limit ?
Some do not even k now the markers in their tyres.
Do you guys have seasonal tyres up there like we do in Europe? ie Winter tyres and summer tyres?

Tire care is as important to me as engine care, etc

I'm on the west coast so no adverse weather here, only Hajj and other east coasters and folks up north near Canada need to do the seasonal tires.

I do all season tires on my daily drivers and high performance on the hobby cars. The bike gets the best tire that money can buy

Ahah I have noted that down on my hard back notebook of noise makers, Ambode must hear this.
We don't do the rotation in the Uk, but in the rest of the EU you are stopped and made to change them there and then or you car goes to the pound.

erico2k2:

says who?

I've been sold "expired" tires before in the USA.

When I contacted the manufacturer they told me that it's just a suggestion and that tires don't expire when stored properly indoors but when out in the element.

So I ran them and they were fine.
