Overloading Tyres Is Dangerous


Overloading Tyres Is Dangerous

Most of us travel in cars, vans and even motorhomes on a regular basis, this can be for work or everyday life. Using a vehicle means that we can transport lots of our goods and possessions whilst we travel on our daily commute or holidays.

What we often fail to realise is that with every item added we are increasing the weight of our vehicle and the load on our tyres.

Tyres simply can’t bear unlimited weight! Just because your van has enough space to fit that bike, tools, and a camping gear such as a portable fridge packed with food doesn’t mean your tyres can cope. The same applies to an SUV towing a trailer or a car with a roof box piled high for a road trip.

To ensure that you have a safe trip, it is crucial not to overload your vehicle and your tyres weight carrying capacity. To help with additional weight, it’s important to adjust your tyre pressure depending on the weight you have added.

Why Overloading Is Dangerous?

Your vehicle’s tyres are doing the hard work of supporting the total weight of the vehicle and withstanding deformations, speed, heat and incredible forces. Build up of heat can cause exfoliation and separation of the tyres tread as well as the sidewall cord becoming damaged. This can continue long after the extra load has been removed. If your vehicle remains overloaded then these forces are multiplied and the risk of a blowout and serious accident are increased.

Each tyre type has a specific weight limit that you shouldn’t exceed or it will fail – think about what could happen if you experienced a blowout in your overloaded car at high speed on a busy motorway, the result could be devastating for you and other motorists.

Consistently using tyres on the top of their weight limit degrades tyres the same as overloading them for a short time. If a tyre has already been underinflated or damaged, even a small extra load can lead to a blowout.

How You Can Avoid Overloading

1. Know Your Tyres Limits. Initially, you need to find out how much weight your tyres need to support, this information can be found in your vehicles owner’s manual or on the sticker placed on the driver’ doorframe.

Next check the tyre’s maximum load capacity on its sidewall, this must be equal to or more than the total load you are going to carry in your vehicle. In this case, your tyres must be inflated to their maximum pressure and must not be exceeded.

Let’s assume that information on the tyre’s sidewall says “Max 2,000 lb @ 35 psi”. This means that the tyre can carry the maximum of 2,000 pounds being inflated to no more than 35 pounds per square inch. It also means that because your car has 4 tyres, the total weight of the car and baggage mustn’t exceed 8,000 pounds in total.

2. Choose The Right Tyres. If you need to carry heavy loads on a regular basis, consider changing your tyres for a set of the same size but a higher load capacity. Speak to our team or a tyre specialist before opting for larger tyres. Another solution might be to increase pressure in tyres if their maximum pressure limit allows doing so.
