No. Neither repairs to externally applied caps nor liquid sealants can be considered permanent repairs. Tyre manufacturers cannot be held responsible for problems arising from their use. For repairs on run-flat self-supporting tires, contact the respective tire manufacturer. However, if you don`t drive many miles, ten years is the recommended time to change the tires, even if they appear to be in working order. The same rules apply to spare tyres. Depending on where you live in the world, you should consider some important SUV tire numbers, not only because these are often legal requirements, but also because they help extend the life of your tires and keep you safe to drive. The 15-point test of a TÜV includes the tyres. The spare wheel is not included in the control system.
The test covers the legal status, safety, size and type of tyre and tread depth. Tyres that do not meet the minimum legal requirements do not receive a TÜV certificate for the vehicle. For more information on testing a vehicle, see: Tyre and safety experts believe that the legal minimum of 1.6mm is not enough to ensure safety – most recommend a minimum tread depth of 3mm for tyre changes. The vast majority of tires used today do not require inner tubes, and many wheels and tires cannot be used with them. Linemen sometimes recommend fitting inner tubes on caravan tires when it is neither necessary nor appropriate. Seek expert advice before such use. The valves vary in length. Make sure that the valve used for the wheel and the attached fairing are correct. Always install new tubeless valves when new tubeless tires are installed.
However, a more accurate and reliable way is to use a depth gauge. It is small enough to fit in the glove compartment and gives an accurate measurement of the tread depth of your tires. Use a profile depth gauge – a tool that allows you to measure quickly and easily. High-end tire manufacturers mold TWIs into the design of the tire tread pattern. It is easy to identify; It consists of six or more small frictions at the bottom of the main tread grooves, which are usually 1.6 mm to 2 mm above the base of the groove. The legal limit of 1.6 mm is reached when the tyre wears out on the tread wear indicators in the main groove – as soon as this happens, the tyre must be replaced.

Of course, it`s not always possible to find the same make and model of tires, especially if your local repair shop no longer has your model in stock.
It is not economical to replace an entire set if you only need to replace one or two tires. Temporary-use spare tires often differ in size from standard road tires and usage restrictions apply. If the tread pattern is at the same height as the markers, the tyre reaches its legal minimum limit. When checking tires, make sure there are no deep cuts on the sidewalls and no bulges. Misalignment of the wheels or worn suspension can lead to uneven wear on the inner or outer edge of the tire while the tread remains intact. You can check the condition of your tires by running a 20p piece along the tread – the outer edge of a 20p is 1.6mm thick, so if the tread is less than this mark, it will likely be less than the legal tread depth. The legal minimum tread depth in the UK is 1.6mm on a continuous tread covering the central three-quarters of the tread width and bypassing its entire circumference. A tire tread check begins with a thorough visual inspection. Start by turning the steering wheel to see the entire surface of the tread. They look for signs of irregular wear that could affect one area of the tread more than another.
If the tires wear evenly, you need to determine if you have enough tread on your tire. Book a free tire check A quick visual check of your tread depth can be done by simply looking at the wear indicators you`ll find in the grooves of the tread drawing. Trailers and caravans may be stored during the winter months and tires may deteriorate. It is important to check their tread depth as well as their pressure and general condition. The legal tread depth of 1.6 mm applies to the centre three-quarters of the width of a tyre over its entire circumference. Tire treads are designed to provide good grip on wet roads, but wet grip usually decreases as tread depth approaches the legal minimum. Motorists should take this into account and reduce speed when driving in the wet. For the same reason, motorists may consider replacing tires before the tread depth reaches the legal minimum. Temporary-use spare tires are often different in size than standard road tires and usage restrictions apply. Failure to follow the instructions in the vehicle manual and/or on the spare wheel or tire sidewall can have serious consequences.
Do not exceed the recommended speed limit when using a spare tire for temporary use and respect the minimum air pressure. Caravans and other light trailers are exempt from the TÜV type test. However, to be roadworthy, there are legal safety requirements that must be met. An annual service by a competent service agent (e.g. a member of the Approved Workshop Scheme www.approvedworkshops.co.uk) verifies this and also inspects the residential parts of the caravan, resulting in a safer and more reliable holiday. Take a look at our press article for more information. Tyre fitting and repair should only be carried out by a qualified tyre specialist who has the necessary equipment and expertise. Improper installation can lead to driver injuries and damage to tires and rims. Wheels should be balanced or replaced based on tire pressure. In addition, drivers can expect penalty points and fines if tires with tread depth below the legal limit are found. To ensure compliance with tread depth regulations throughout Europe, a minimum tread depth of 1.6 mm over the entire tread width is recommended.
For safety reasons, it is advisable to replace tires before they reach this legal limit. Without sufficient tread depth, your tires may not function properly in wet conditions, reducing your safety on the road. It is therefore advisable to consider replacing your tires well before they reach the legal minimum. In addition, drivers whose tyres do not meet the minimum tread depth requirements face a fine of up to £2,500 and three penalty points for each illegal tyre. An improperly mounted or fit-fitting electric caravan mover that operates with rollers pressing against the trailer`s tires could damage the tires. If the rollers push with too much force, the tire could be deformed to such an extent that its structure is damaged, and moving companies should never be left with the rollers against the tires when not in use. Similarly, too low pressure could turn the roller against the tire, causing abrasion on the tire surface. The rollers can also spin when the mover is used to force the caravan against or over an excessively large obstacle. In situations where your tires do not have sufficient tread depth to properly remove water from the road surface, the particularly dangerous phenomenon of aquaplaning can occur. During aquaplaning, your tires lose contact with the road surface and roll over the surface of the water. Without contact with the road, you cannot accelerate, brake or steer effectively, which greatly increases the risk of being involved in an accident.
To reduce the risk of aquaplaning, regularly check the tread depth of your tire. See how aquaplaning can affect your safety. Federal regulations help keep highways safe by setting minimum standards for tires. Standards include: Balancing caravan tires has some advantages; Improved tire durability and wheel bearing wear. Tire imbalance becomes increasingly evident from around 55 miles per hour, so balancing is especially useful if heavy highway towing is likely. The most important thing to check is the age of the tires. Even though it is visually good and the caravan has been used with caution for modest miles, you may need to replace the tires due to their age. Especially for older caravans, tire specifications may need to be updated, either to allow overseas use or simply because the original tire type is no longer available. It`s as simple as that. Note that although the legal limit is 1.6mm, anything less than 3mm can seriously affect performance and safety. The correct pressures for your car`s tires can be found in the fuel filler door or in your owner`s manual.
If possible, use the same pressure gauge to keep all readings consistent and check them weekly. Worn tyres mean that the only contact surface between you and the road is beyond its peak. Living in the UK means regularly battling adverse weather conditions, so it`s best to check your tyres regularly to make sure they`re fit for use. But how often is it frequent? Daniel Bezer, tire expert at TOTD, recommends: Whether you replace them at 1.6mm, 2mm or 3mm depends on personal preferences and tire quality. However, it should be noted that tires near or at the legal limit may be more sensitive to aquaplaning because there is less tread depth to disperse water.
