All About Tyres
Are you crazy or crazy about tyres?
Tyre people think normal people are crazy. Because normal people don't understand how important it is to have good tyres which are kept in good condition.
Normal people think tyre people are crazy. How can they be so passionate about something which is black, round and boring?
Scroll to the bottom of the page if you want understand tyres. In the meantime here's why normal people are crazy when it comes to tyres.
This tyre could burst any day. It would skid on wet roads.
The inside of the tyre has worn way more than the outside indicating that the car needs a wheel alignment badly. The legal tyre tread depth is well below the 1.5 mm minimum. One side of the tyre has no grooves at all. So it can't channel away water from a wet road. This car would skid easily. Worst of all the tyre has worn through to it's fabric construction which is now exposed and vulnerable to damage. This tyre is likely to come apart suddenly and lose its air pressure instantly resulting in a dangerous blowout. Let's hope the driver is going slowly when it happens.
This Volkswagen Polo needs 2 new tyres on the front and the driver is crazy.
How to prevent this. When your car is parked turn the steering hard to one side so you can see all the tread. If it's badly worn or worn on one side take it to your nearest tyre shop.
These SUV tyres are mismatched. It wouldn't stop in a straight line.
The Nissan X-Trail tyres above have different tread patterns. The one on the right has small tread blocks and wide straight grooves giving it good traction in the wet. The one on the left has large tread blocks, less grooves and would be better in the dry. Crazy!
Having mismatched tyres can cause your car to turn when you want it go straight, or go straight when you want it to turn.
Ideally each corner of your car should have the same amount of grip. So the car goes straight when you brake or accelerate. And so the car doesn't understeer or oversteer when it goes around a corner.
You must have matching tyres on the same axel. Both rear tyres must be the same. Both front tyres must be the same. The pair on the front should be the same or similar to the ones on the rear.
This Nissan X-Trail needs 2 new tyres on the rear.
Understanding Tyres. We've tried to make understanding tyres easy.
Think of tyres as your car's shoes, and the tread as the sole. Some shoes have hard, smooth soles and are treacherously slippery. Others have moulded patterns and rubber that grips to give you good traction.
Many components go in to a modern tyre to give it the performance, handling and safety that we've come to expect.
A radial tyre starts with a shell: steel belts make up the spine of the tyre, while on the sides, bead wires have the primary task of holding the tyre firmly on the rim and seal in the air. The body 'plies' provide the strength to constrain the forces created by the internal air pressure, and work in conjunction with the bead to maintain the tread in full contact with the road surface.
Finally, the grooves in the tread are specially designed to remove water from under the tyre in wet conditions. This is why a 'bald' tyre is so dangerous; as the tread wears down, the tyre's ability to remove water, and therefore have grip, is significantly reduced.
Here's a technical tyre description of the components which make a high quality tyre, in this case the Yokohama ADVAN Sport.
1. Round profile
2. Jointless triple edge cover (Full nylon cover)
3. Overlapped jointless winding
4. High-hardness under the tread compound
5.High tension steel belts
6. Rayon carcass (Some tyres have a polyester carcass)
7. High-harness bead filler
8. Side steel reinforcement
9. High-harness side compound
A tyre is a package designed to give you tens of thousands of kilometres of safe, comfortable driving. And when the only thing between you and the road at speeds up to 110km/h is the tyres, you cannot cut corners.

Want to make sense of the numbers and codes on your tyres? It's easy to find out how to find your tyre size.
DID YOU KNOW... The minimum legal tread depth on a tyre is 1.5mm - about the height of the head on a match. On the side of your tyres you can find little arrows pointing to 'tread wear indicator' bars. When the tread wears down to this level, the tyres need replacing.
