How Does Hot Weather Affect Vehicle’s Tyre Pressure?

Many drivers start worrying about their tyres as the cold weather approaches, but changing temperatures at any time of year can change the air pressure in your vehicle’s tyres. If the tyre pressure changes it can affect handling, steering performance, braking distance, and fuel economy. It will also affect how long your Bridgestone tyres will last and remain in good condition.

Keeping an eye on your tyre pressure during warmer weather is important for driving on safe tyres. In this blog post, we will explain what to look out for and how you can keep your tyres at their best in the heat.

Changing Temperature and Tyre Pressure

Tyres consist of pressurised air inside a tube of reinforced rubber. Just like gas, the air will expand as the temperature increases and contract as the temperature decreases, which will raise or lower the pressure of your tyres.

Other factors can also impact your tyre pressure, such as friction from the road surface which generates heat, but the main cause of changing a tyre pressure is the changing temperature in simple owners the weather.

But how much does weather affect tyre pressure? As a rule of thumb, every 10 degrees of rise or fall in temperature affects a tyre pressure by 1 to 2 PSI. So change in your tyre pressure from summer to winter can be up to a 15% difference and this is enough to change the handling and performance of your vehicle.

Does Hot Wheather Affect Tyre Pressure?

Resistance and friction can cause a build-up of heat inside the tyres. The warming effect of the weather then adds up further pressure. But most tyres are made with built-in air pressure tolerations. Unless the weather conditions are very extreme, you should be able to drive your vehicle in hot weather without changing the tyre pressure, as long as you keep an eye on the TMPS and look for any signs of overheating.

Keep in mind that the tyre pressure recommended by the vehicle manufacturer is set for cold temperatures, so tyres should always be inflated once they are cool down.

How to Spot an Overheated Tyre?

The dark black colour and materials of your tyres make them perfect for absorbing heat, so if they are hot as you touch the surface, they are close to overheating. If you face the same situation, it’s time to stop driving and let your tyres cool down.

The hotter the tyre, the higher the pressure will be, so releasing some air out may seem like a good way of dealing with overheated tyres. But, doing this could lead to underinflated tyres when their temperature returns to normal.

What are the Risks of Overinflated Tyres?

If your vehicle tyre pressure is too high, it can significantly increase the risk of blowout. It can also reduce your traction since most of the tread is not in contact with the road. This will make your handling and traction less responsive, and your journey less safe.

We recommend you check tyre pressure in all weather conditions, even if you are not driving often or not driving. Also, reinflating is a must required, take your time to check over the tyre for any signs of damage. This way, you will be aware of any issues before they become more serious, or even dangerous.

What is a Tyre Monitoring System in My Vehicle?

Nowadays almost all of the passenger vehicles have a built-in tyre pressure monitoring system (TMPS). Using different sensors in all four tyres, the TPMS will give an audible or visual warning notification if the air pressure is too low. There are some cases where TPMS is not a reliable solution, and it won’t alert you if the pressure is too high, so ensure to check your tyre pressure manually by using a gauge.

Does Cold Wheather Affect Tyre Pressure?

For every 10 degrees of temperature drop, the tyres will drop 1-2 psi at most. It is important to keep your tyres within the manufacturer-recommended PSI to maintain friction. So you can expect the tyre pressure to drop about 2 to 3 PSI if the outside air temperature decreases by 30 degrees from the last pressure adjustment.

This is the case, where it is okay to deviate from the manufacturer-recommended PSI levels to maintain the longevity and functionality of the tyres.

In a situation of freezing weather, if you leave the tyres underinflated, not only does it cause your steering to be difficult, but it also generates more friction which causes tyres to be prematurely damaged, prematurely and skid easily on a wet road. Overinfalting your Car tyres Milton Keynes can make your driving experience more rougher.

Guide To MOT Test

The United Kingdom attaches great importance to the maintenance of a safe and roadworthy vehicle fleet. The Ministry of Transport (MOT) test is an annual inspection which all vehicles must complete in order to ensure that they meet safety and environmental standards. In this article, we will explore in detail the history of the MOT test, why it is necessary, and what it involves.

What is the MOT test?

An MOT test is an annual test carried out on virtually every vehicle in the UK which determines the vehicle’s safety, road worthiness and exhaust emissions. The test is performed in approved garages, testing centers, and is obligatory upon almost all vehicles older than three years (four years in Northern Ireland). The availability of the test certificate reassures the driver that his or her vehicle and the road users in general are safe.

When Does a New Car Need its First MOT Test?

A new car under the law, performs its first MOT no earlier than three years or, in other words, not earlier than three years from his date of registration. The date of a vehicle's registration may be located on the V5C registration certificate. Furthermore, following the first test, the said MOT examination must also be carried out every year so as to ascertain that the car remains roadworthy.

What Does an MOT Test Cover?

The MOT test is a procedure that involves a thorough examination of the safety and road worthiness of a vehicle. The examination includes a number of checks on:

Exhaust Emissions: This test examines the exhaust emissions of the vehicle to check its compliance. It also has examination of the muffler system, catalytic converter and dpf – diesel particulate filter.
General Roadworthiness: The assessment, also known as the overall inspection of the car, takes into account other aspects of the car such as tires, brakes, suspension, steering, and bodywork.
Vehicle Safety: The assessment of the vehicle safety features such as belt, airbag, and abs.
Lights and Electrical Equipment: This checks lighting features such as that of head lamps, tail lamps, break lamps, indicators as well as the presence of other lights.
Tyres: This test assesses the quality, dimensions and tread wear of the wheel in relation to set regulations.
Braking Systems: The test examines the overall condition and efficiency of the braking system, paying attention to the brake pads, discs, and drum components.
Body and Structural Integrity: Assessment of the body's exterior and internal structure for damages, tears, dents, or signs of rust is conducted.
Seats and Safety features: This includes testing all seats and safety belts to make sure that they are working properly and in a suitable condition
Horns and other Warning Equipment: The test includes an assessment of the working efficiency of the horn and other warning equipment such as hazard lights and ensuring they are in working order.
Suspension and Steering: The assessment looks at the state and operational efficacy of the suspension and steering systems.

What Happens if My Vehicle Fails the MOT Test?

In the event that the vehicle does not manage to pass the MOT test, you will have to repair all the defects found in the course of the test that led to the failure. You may have the repairs performed at the testing station or some other garage instead. After all the repairs have been performed, you can Book MOT Reading test again.

Tips for Passing the MOT

Here are some helpful tips that will help you pass the MOT test tips:

Prior to taking your vehicle to the MOT test, ensure it is roadworthy and fit for the test. For instance check the tyres, oil, and brake fluids’ levels and correct those that are out of the normal range before the test.
Ensure that all lights on the vehicle work including; main beam, tail lights, and brake lights.
Inspect the front windscreen and if there are any chips or cracks consider replacing it.
Check the condition of the vehicle’s exhaust pipes and ensure there are no holes or leakage.
If there are seat belts fitted in the vehicle, check their condition and whether they are working.
A check should also be done on the steering wheel especially whether it is tight and that the horn is in working condition.

These tips can help to boost your chances of a successful outcome during the MOT test and help to eliminate the need for expensive repairs.

How Much Does an MOT Cost?

In the United Kingdom consumers and car owners pay different prices for the MOT test that is determined by the automobile and the particular testing center. To begin with, it is important to note that the UK government has set a maximum charge that can be levied on an MOT test that is 54.85 pounds for cars and 29.65 pounds for motorcycles at present. Nonetheless, a majority of the testing centers provide some price cuts and special offers, with the lowest price rated at roughly 20-30 dollars. It is also possible for some garages to have an arrangement of providing a free retest should your automobile not pass the first test. However, it is important to note that do Always compare rates.

Conclusion

Having looked at the above, it is right to say that the MOT test is a mandatory cause for concern to vehicle owners in the UK. It assures that vehicles are roadworthy, safe, and do not degrade the environment in any way. Knowing what the MOT test entails and its timing, will help the driver to keep their Car Repair Reading within the UK’s regulated standards.
