There is a good chance everyone will experience a puncture at sometime in their driving lives. But it’s amazing how many people still don’t know how to change a car tyre and rely on the help of a passer-by.

There is one place you should not attempt to change a tyre yourself- on the hard shoulder of a busy road. In this instance call the emergency services and retreat to safe distance until they arrive.

In all other situations changing a car tyre is not as difficult as it may seem. This article is a guide to how it is done:

1) Find a safe place to stop, on flat ground. If it’s dark look for somewhere with adequate lighting. Park as far away from traffic as possible and put your hazard lights on.

2) Turn the engine off, pull the handbrake on and put the car into first gear or ‘park’ if it’s an automatic.

3) Find the tools for the job. These will include a jack, wheel wrench and the spare tyre. All are usually located in the boot of a car.

4) Remove the hubcap or plastic wheel cover using the flat end of the wheel wrench or a screw driver.

5) Loosen the wheel nuts by turning half a turn in an anti clockwise direction. Do NOT remove them. That happens at a later stage.

Tight wheel nuts can be the hardest part of changing a car tyre. If the wheel nuts are proving stubborn use a metal tube to extend the wheel wrench’s handle and provide extra leverage. Alternatively place one foot on the handle of the wheel wrench and carefully use your body weight until the nut is loosened.

Many cars have a locking wheel nut to prevent theft. This requires a special attachment which is often found in a car’s glove compartment.

6) Consult the vehicle’s handbook to find where to place the jack. This is important because if it’s put in the wrong place the car could slip off the jack and cause serious injury.

Look for a reinforced lip on the underside of the vehicle close to the wheel arch.

When the jack is securely attached raise the car until there is enough room to remove the punctured tyre and replace it with the fully inflated spare.

7) Now continue to remove all of the wheel nuts and place them somewhere safe nearby- not near an open drain! Remove the punctured car tyre and replace with the spare tyre.

8.) Replace and tighten the wheel nuts. Don’t try to hard to tighten them until the car is off the jack.

9) Slowly lower the car down off the jack. Now tighten the nuts again. Remember to return the jack and the wheel wrench to the boot of the car.

10) Replace the hubcap or plastic wheel cover and continue with your journey.

At the first opportunity stop at a petrol station and check the new tyre is inflated to the correct pressure, the same as the other car tyres.

If in any doubt about your tyre changing ability, call into to your nearest garage or car tyre specialist.

As the cold and wet winter months approach now is a good time to check the condition of your car tyres. Car tyres are the only point of contact between your vehicle and the road. Any signs of wear or damage will decrease the performance of your tyres and endanger not only yourself but other road users too.

It is especially important to check your car tyres during winter as there is greater chance you will be driving in wet and icy conditions.

Based on the information provided by TyreSafe, three essential car tyre checks include:

1) Check the Tread Depth

Tread depth must be a minimum of 1.6mm. This is the legal minimum and applies to the entire circumference of the tyre.

Most tyres have a wear indicator built into the tread. Look for a horizontal bar of rubber located between the tread patterns, at a depth of 2mm. When the height of the tread wears down to the height of this bar it is time to replace your car tyres.

In the wet conditions that winter brings it is good advice to change your tyres well before they reach this limit. A tyre’s grip deteriorates more rapidly in the second half of its tread life and in the wet stopping distances is significantly increased.

If you notice unusual wear on your car tyre, such as excess wear on one edge, it may be a result of your wheels being incorrectly aligned. Consult your local garage or a tyre specialist to check your vehicle’s tracking.

2) Check Tyre Pressure

A car tyre that is inflated below its recommended pressure will wear faster because of its higher operating temperature and the extra flexing of the rubber. This causes deterioration of the tyre casing and rapid wear of the tread shoulders.

Over inflation can also increase wear due to the decreased size of the contact area between the car tyre and the road. This accelerates the wear in the centre of the tread, an area importantant for protecting the tyre against impact damage.

Driving with unequal pressures in your car tyres will lead to unusual and accelerated wear. It can be potentially dangerous as the balance of the car is upset and cornering with unevenly pressurised tyres can lead to unpredictable results.

3) Check Condition of Tyres

Remove any stones and other objects embedded in a car tyre’s tread. If you find a nail do not remove it as the tyre will rapidly deflate. Instead take the tyre to a specialist who may be able to repair the puncture.

Check for any unusual bulges or lumps as these are often a sign of internal damage.

Inspect the tread and sidewall rubber for sign of cracking. Crazing and cracking due to weather exposure usually becomes evident on car tyres that are more than five years old. However tyres on vehicles that are parked outside will degrade faster than those kept in a garage.

At the first sign of cracking change the tyre rather than risking a blowout when the vehicle is in motion.

Car tyres should be checked at least once a month. Regular inspection becomes more important the longer the tyre is in use. If any damage or unusual wear is found consult a car tyre specialist who will determine whether the tyre needs to be replaced.

There are many different types of car tyres. The one you choose will depend on factors such as the make of car, driving style, where you live, the time of year and how your car is used.

For instance if you spend a lot of your working day driving up and down the motorways, you will need a hard wearing tyre that doesn’t create a lot of noise. If you live in the countryside a tyre that provides better grip on muddy roads would be more suitable.

This article identifies five different types of car tyres and highlights some of the differences between them:

1) Standard/ All Season Tyre

Your car was probably driven out of the factory on all season tyres. It is an average tyre that is suitable for all year round use. It works equally well in the wet and the dry.

The tread block pattern is designed not to be noisy when used on standard roads but enables adequate water dispersion to provide grip in wet conditions.

The rubber used is a harder compound to extend the tyre’s life. This can comprise on handling and cornering but for the majority of drivers it is not noticeable.

2) Performance Tyre

Also known as summer tyres, performance tyres are designed for provide excellent grip in the dry. Often used on fast cars or for a driver whose style requires increased handling performance. They can be used all year round if you live in a region with a warm climate and little rain.

A soft rubber compound is used which decreases the lifespan of the tyre but provides enhanced grip.

It is important that the car tyres are kept in excellent condition. Driving in the wet is hard enough with these tyres but if there is any sign of wear it is virtually impossible to get good grip.

3) Winter Tyre

Winter car tyres are designed to cope with the poor weather and difficult driving conditions that the winter season brings. They can handle snow and ice. Winter tyres can have small metal studs embedded into the tread for extra grip in extreme conditions.

The tread block pattern on winter car tyres is larger and more pronounced than on standard tyres. This improves grip but also increases the tyres’ operating noise.

These tyres cannot be used all year round because in dry conditions they wear out extremely quickly and damage the road surface.

4) All Terrain Tyre

All terrain tyres provide good grip on loose surfaces such as dirt and sand. Often used by off road vehicles, they can be used on standard roads but are very noisy.

Like the winter tyre the tread block pattern is large to improve grip. The tyre’s sidewalls are stiffer to cope with uneven surfaces and unexpected potholes.

Mud tyres are an extreme type of all terrain tyres, designed to be used in mud and dirt. They have very large tread block patterns that are only suitable for driving on that type of terrain.

5) Run Flat Tyres

Run flat tyres are a relatively new concept but are now becoming more common on new cars. They are designed to minimise the loss of handling that occurs after a puncture.

The car tyre can operate without air to enable the vehicle to continue to be driven. However this is only suitable for a short distance and at a reduced speed, until the tyre can be safely changed.

For further advice consult a car tyre specialist who will provide you with impartial advice on the best tyres for your vehicle.

The latest Bond car for the film “Quantum of Solace” is the Aston Martin DBS. Low-profile 20inch car tyres, smooth lines and curves, flared wheel arches and an overstated front grill; it is the epitomy of British cool with which to save the world.

The Aston Martin’s 6.0-litre V12 engine has a distinctive throaty roar that is capable of 0-62mph in 4.3 seconds and has a top speed of 191mph.

This has to rate as one of Bond’s best looking cars but to compare I have compiled a list of 5 other classic Bond cars:

1) Recently voted the most iconic car of all time, the Aston Martin DB5 appeared in ‘Thunderball’, ‘Goldfinger’ and more recently ‘Casino Royal’.

It was originally introduced in 1963. Its film debut was in the 1964 Goldfinger, starring alongside Sean Connery. Its distinctive silver livery, streamlined bodywork and large front grill was new for its time.

However the aesthetically pleasing body hid a vast array of lethal surprises to confound even the most troublesome of Bond’s enemies. You may remember a scene in Goldfinger where one rear brake light spurted oil onto the road. And the other released triple-spiked nails to burst the car tyres of the pursuing villains.

Other clever features devised by Q included a revolving licence plate, an exhaust that expelled smoke-screen canisters and wheel hubs that revealed knives to slash car tyres.

2) The white Lotus Elite used by Roger Moore in 1977 ‘The Spy Who Loved Me’ surprised everyone with its ability to be driven underwater.

In an attempt to escape a pursuing helicopter the Lotus was driven off a pier into the sea. At the time you would have thought this was the end for the car. But with typical Bond creativity the car tyres retract and it was transformed into an operational submarine, complete with fins and a periscope. The persistent helicopter soon meets its demise with a missile fired from the car beneath the water.

3) The 1987 film ‘The Living Daylights’ saw a return to the Aston Martin. This Aston Martin V8 had a powerful engine to compliment its macho looks. It used a fuel injection system that replaced carburetion. Due to the compact nature of this new technology the car could be designed with a flat bonnet, unlike the curved bonnets of its predecessors.

As with any Bond car there were a number of clever additions including self retractable spikes in the car tyres for extra grip on icy surfaces, lasers behind the front hubcaps and missile launchers behind the headlights.

4) It was bold move not to use a British manufactured car in the 1999 ‘The World Is Not Enough’ but BMW Z8 soon won over the Bond fan. Its retro styling and red leather interior was backed up by a 400-horsepower V8 engine that had a top speed of 158mph.

Hidden accessories included missile launchers in the side vents and a windscreen that displayed important data. The car could be operated remotely using the key chain.

5) The Aston Martin was back in the 2002 ‘Die Another Day’ starring Pierce Brosnan. This time it was the V12 Vanquish, sometimes referred to as ‘a DB9 on steroids’.

The classic styled V12 nearly met its match when confronted with the villain’s Jaguar XKR. But the front mounted Gatling gun, rocket launchers in the doors and bombs in the boot soon put paid to that.

Two other clever features, which eventually won the battle for Bond, were the car’s ability to become invisible and the spikes hidden in the car tyres. The latter helped the car drive up an ice wall to avoid the fast approaching enemy, causing the Jaguar to have a unceremonious demise at the bottom of a lake.

As wonderful as the Bond cars are, thankfully features like spikes in car tyres have not become common place on our modern vehicles. If they ever do be sure to consult a specialist before changing a punctured car tyre.
