You should buy new tires because of the improved safety offered by sufficient profile depth. In addition, new tires drive better and help to reduce fuel consumption.

The professionals at will be pleased to help when you select new tires and, together with you, will examine the purpose of the tires and the most suitable profile. Aeolus offers a wide range of tires for trucks, and trailers. Click here for a dealer near you

There are a number of obvious reasons for replacing tyres.

  1. Damage: Damage can be caused by driving against solid objects or sharp edges (pavements, holes in road surfaces, etc.) Your tire specialist will be able tell you whether damage to the tire presents a risk to safety.
  2. Age: When in use, it is difficult to predict the exact life span of tires. That is why they should be regularly checked for signs of fatigue, dehydration and ageing. Tires that are (too) old may lose grip, which presents a risk to safety.
  3. Wear and tear: Regularly check, or instruct someone else to check, the profile depth on your tires. In most countries, the legal minimum profile depth is 1.6 mm. However, Aeolus recommends that tires be replaced as soon as profile depth reaches 2.0 mm. This means you will always drive safely and prevents you from breaking the law when your tires are replaced a little too late. Please note: the rules for profile depth also apply to reserve tires!

Yes, because the balance will change once a new tire is placed on the wheel rim. It is thus essential to have the wheels balanced. This is important for driving comfort and good vehicle and tire performance, as well as for safety, wear and tear and predictable steering and braking behaviour. Your tire specialist will be able to evaluate whether it is necessary to check alignment.

All tires feature a production date. This helps to ensure that your tires are not too old. That said, tires can have a long life span if they are correctly stored. The DOT number indicates the production date. The side of the tire features a 4-figure number (which is preceded by the abbreviation ‘DOT’). These four figures refer to the production date: The first two figures identify the week (from 01 to 52) and the last two the year of production

A tire’s load-bearing capacity indicates the maximum weight that can be exerted on the tire. You will not immediately notice signs of overloading and excessive speed – thus higher than permitted – on your tires. However, overloading has the same impact on the tire as insufficient air pressure.  Tires will wear out faster and the risk of a flat tire will increase! If you are overly careless and have excessive load, insufficient air pressure, high speed and a high external temperature, you will be exposing yourself to irresponsible risks. If you still have questions, please Contact Us.

It is always wise to regularly check your tires and remove any stones from the profile. If you are going to store the tires, for example, after changing from summer to winter tires and vice versa, it is wise to clean them with soap and clean water. When cleaning your tires on the wheel trim using a high-pressure cleaner, make sure you retain a distance of 20 cm. You may otherwise damage the side of the tire or spray dirt between the tire and the wheel rim, which may cause the tire to slip on the wheel rim.

You must remember a few rules when storing your tires after changing them. Tires that are stored on the wheel rim should be stacked on top of each other on a flat surface or should be hung up; never place them upright. Tires without the wheel rim should be placed upright, although they can also be stored horizontally. Tires must always be stored in a dry, cool and dark place. If you do not store your tires correctly, their physical properties will change and their life span and safety will be reduced

Tire pressure has a major impact on fuel consumption. You will consume less fuel when the pressure is correct than when it is insufficient. In general, you should check the pressure every four weeks. In case of intensive use (long journey, high speed, heavy load), you should perform an additional check on the pressure.  Manufacturers mention the required tire pressure in the instruction booklet and (often) on the truck itself. Always respect the indicated levels.

You should note that:

  • the tire is cold when you measure the pressure.
  • heightened pressure is completely normal when driving and does not need to be corrected.
  • the pressure of tires on the same axle must be identical.
  • pressure can differ between front and rear axel.
  • valve caps are tightened sufficiently to protect the valve from dust and dirt. This helps to prevent leaks.
  • defect valve caps are replaced immediately

Vibrations indicate that your vehicle has a problem that requires attention. The tires, steering column and suspension/shock absorbers must be checked to detect potential reasons for the vibrations. If you fail to address the vibrations, this will increase wear and tear on the tires and the suspension. You will thus endanger yourself and your fellow road users.
