Easter holidays and summer vacations are perfect times to take your caravan out of storage. However, before hitching it to the tow bar and hitting the road, it’s important to check the condition of your tires. Drivers often forget to carry out these checks because they use their caravan less than their car.

Yet, since the tires are the only part of the caravan in constant contact with the road, they must be changed on time for safety reasons. To ensure your safety, that of your passengers, and that of other road users, here are some guidelines to help you know when you need to replace your caravan tires.

Caravan: Consider the age of your tires

Caravan owners want to avoid changing their vehicle’s tires unnecessarily. For some, changing their caravan tires can represent a significant investment. But answer this question: is your safety on the road worth a price? Now you know why you shouldn’t be negligent when it comes to changing your tires. To know when your caravan needs new tires, you can consider the age of the tires it’s currently equipped with. In fact, the condition of a caravan tire deteriorates with age, even if you don’t use the vehicle. However, there’s a slight difference. To determine the age of your tires, you shouldn’t consider the purchase date, much less the installation date, but rather the manufacturing date. You can find good quality caravan tires at the best prices on online sites. These sites offer tires from many reliable brands in a variety of sizes.

You can easily find this information on the sidewall of your tires. The caravan tire’s manufacturing date is integrated into the DOT code. This is a series of numbers, the last four of which represent the tire’s manufacturing date. If the last four digits are, for example, 3811, then you can deduce that the tire was manufactured in the 38th week of 2011. A caravan tire older than 6 years must be replaced.

As tires age, they begin to degrade due to oxidation and deterioration of the rubber, especially in hot and humid weather. According to tire industry experts, when a tire reaches 6 years old, the rubber it is made of is so degraded that the wheel becomes potentially dangerous. However,

if you are frequently on the road, you should replace your tires as soon as possible, for example, 3 years after the last replacement.

Tread depth, a reliable indicatorCaravans travel fewer kilometers than the vehicles that tow them. Realistically, they cover about 3,000 km per year. One might therefore be tempted to assume that caravan tires need replacing due to age rather than wear. However, there are many factors that influence

  • caravan tire deterioration,
  • such as:
  • sun exposure;
  • the weight of the caravan;

the immediate environment surrounding the tires; caravan tire fatigue due to repeated minor impacts…The length of time the caravan is stored is also a potential source of wear. In fact, some parts of the tires can bear a higher load than others due to the caravan’s inactivity. To estimate the wear level of your tires, you can

measure the tread depth. The more worn the tread, the more it loses its traction efficiency.New tires are generally delivered with a tread depth of approximately 8 mm. When this tread depth reaches 3 mm due to tire wear, the caravan’s stopping distance can be up to twice the vehicle’s total length. When your caravan’s tire tread depth is only 1.6 mm, it’s very alarming.

At this point, the loss of tire grip becomes critical, and your vehicle can travel up to 18 meters before coming to a complete stop after braking. Therefore, it’s important not to wait until the tread depth drops below 1.6 mm before considering tire replacement.

Instead, start looking for a new set as soon as the tread depth falls below 3 mm. Besides the tread depth, other signs of tire wear should not be overlooked. For example, if you see cuts, bulges, or cracks on your tires, have them checked by a specialist. Since these imperfections can lead to traffic accidents, the mechanic will most likely recommend tire replacement.

Loss of caravan tire pressure? Consider replacement!

Low-pressure tires can cause you to lose control of your caravan when towing it. They also increase the risk of wheel failure. Caravan tires typically lose about 1 to 2 psi per month.

However, if your tires require significant inflation pressure (for example, 50 psi or more), you should regularly check their condition. It is recommended to check your caravan tire pressure every two weeks. This is the best way to ensure there are no slow leaks.As soon as you notice an abnormal pressure loss, know that it’s time to replace your tires.

Caravan Tires: Driving Comfort, a Tell-Tale Sign

Your knowledge of your caravan and common sense are other factors that can tell you when you need to replace your tires. If you notice anything unusual while driving your caravan, it’s best to have it checked by a professional. It’s better to be safe than sorry, right? So you know what to do.
