Legal Tyre Limit for Hgv
Application of visibility of date marks and treatment of directional profile tyres Each tyre grinding machine shall be made with a residual tread of approximately 4 mm. After groove, the law of 1mm still applies. It is also required by law that the tire is regrooved in the pattern specified by the tire manufacturer, if he does not pay attention, the tire becomes illegal. If one of the tire cords is exposed during steaming, the tire should be discarded. [N.B. It`s important to keep in mind that economy tires may not have enough extra rubber to fill the tires.] In our last response, we did not say that the date indicator should not be inside the tire. We just described what would happen if the date code was not visible. The indication of the date can be on both sides of the tyre, but if we cannot find it inside the road, we have no choice but to take advisory measures, since one of the requirements of this legislation is that the indication of the date of the tyre must be clearly legible. With respect to the advisory measure, it would be up to the operator to ensure that a date code is legible and that the tire is used legally.
DfT research shows that tyres break down whether they are used or not. Although the tire may have a good tread, the overall condition of the tire will have deteriorated over time. Some respondents raised concerns about our proposal to require the visibility of date markers in all installation configurations (single and twin wheels) to facilitate enforcement. The viewpoints noted that this was not practical “due to the usual practice of turning tires to compensate for wear”, “Since the date indication is raised only on one side of the tire, it is not practical to display the date on the outside of a pair of tires” (dual wheels) and because “some tires are directional, so that they should operate in the opposite rotation to that recommended by the tyre manufacturer.” A retreaded tyre shall be assessed in the same way as a new tyre and its age shall be calculated from the date on which it was reprofiled. To answer Raymond`s question, if your private truck is less than 40 years old, the change in tire regulations applies to you. You must comply with tire requirements for age and age ratings I agree with the rules for old tires on steered axles, but banning a visually safe and legal tire, apart from age, is too strong, when a single failure would suffice. If the date code is not legible during an enforcement check, an inspection certificate would be issued and again, we would expect the tire to be replaced.

Premature tire wear Tire pressure at the vehicle`s recommended pressure level ensures even tire pressure distribution, optimal handling and therefore a more uniform wear rate, which keeps the tires in service longer. This legislation has been in force since the 1st year.
February in effect – Your vehicle should not be used if your tires do not meet the requirements. So if a vehicle built for more than 8 passengers (16) but the seats have been removed to limit passengers to 8 passengers or more, they are exempt from the new tire laws. Hello Can you confirm the above point about retreaded tires? So if a vehicle has a nine-year-old child (date stamped by the manufacturer`s tire), it could be renewed a year before the tread expires. This retreading would give it a new buffer to replace the manufacturer`s buffer, effectively giving this tire another ten-year lifespan? Thank you very much. The TÜV manual says, “Other than for tire inspection,” as you point out. Some of you have asked whether we will report drivers and operators to the Commissioner for Transport if we catch them with tyres that are more than 10 years old or without a readable data code from the manufacturer. A tyre shall be marked as suitable for the application, nominal size, load index/position weighting, speed rating and tyre age code. We expect the driver to detect any visible tyre deterioration, damage or wear during driving checks.
Thank you Peter. Presumably, in the case of rear tires, a visible date indicating that the tire is more than ten years old will also result in a minor error/advice in a Class 5 TÜV test? I could ask a tire fitter to remove the tires from the rims and turn them over so that all the data is visible, either outside or in the box under the bus. But is there any point in paying someone for it if I`m going to end up with the same advice anyway? I`m an amateur and not an operator who prides himself (try!) on showcasing well-maintained “clean” vehicles for testing, but my money unfortunately only works on newer rubber on the front axle. By the way, I fully support the changes to the front tyre rules! Hi Peter, I am now very confused – my motorhome is a converted coach 40` 17000 kg gross with 10 travel seats (driver included) – it is registered as a motorhome. It has a Class IV roadworthiness test – so I guess it`s exempt for the 10-year rule and isn`t required for the roadworthiness test, and if I was stopped, would I be in good condition with tires, but older than 10 years? Please advise you. Therefore, these vehicles are subject to the new tyre regulations with the current number of seats, and this applies to both private and commercial use. If we find an operator with a tire that is more than 10 years old or does not have a date code that results in a prohibition notice marked with an “S”, we will discuss this with the operator first. Can I just get clarification about the tire data stamped on an LNF tire? If you read the outdated DVSA tire management document, if a tire mounted on a dual wheel station has its tire data inside and the inspector cannot read the date, this would be marked as a notice on the side of the road and at the roadworthiness test.
Our local DVSA tester at the TUV station explained to us that this would be a TUV mistake, would it be correct as we want to stay legal and complain and do things right, and in terms of just recommending it against it, how does that affect a company`s OCRS score? So even if I drive it less than 4000 miles a year and replace all the bad tires, no matter how perfect they are, should I throw them away? So vehicles that fall under the small TÜV test – this vehicle is tested in class 4 – are subject to this 10-year-old tyre rule? I have a question about a 17-seater minibus with two rear wheels. Would it be correct to assume that only front single wheels/tires should be less than 10 years old? The four in the back, two on each side, should not necessarily be 10 years old or younger, but the driver should install the tire management system. That`s how the manual reads, but I just wanted to check again. However, you should have all tires of all ages checked regularly by a competent person. This should be part of your tire management and vehicle maintenance system. For example, if an Iveco Euro Cargo or a Daf LF45 has been converted into a motorhome and then undergoes a Class IV test and has no more than 7 seats, is it a mistake to have tyres ten years old or more on the front axle? I wanted to give you an update on the new requirements and answer some of your questions. This should give you time to update your tire management systems before the law changes – to make sure you`re always complying with the new rules. The prohibition on affixing a tyre whose date indication has been damaged, altered or degraded to be illegible applies to the tyres of all vehicles falling within the scope, irrespective of their position on a vehicle.
The real world? By far, not all operators are obliged to use a vehicle everywhere and at all times. Those with older service buses operating in the city wouldn`t consider sending them on a breakdown call for a Spanish shuttle. Similarly, comparing a National Express contractor to someone who performs four marriages a year commercially with an old half-bridge at 30-40 miles per hour is not the same thing. No one wants dangerous tires on their bus, but different circumstances certainly have a role and a unique size that does not always work without massive waste and unnecessary costs. Tyres older than 10 years shall not be fitted to the front steering axle(s) and to a wheel configuration independent of a minibus. If it is a retreaded tire, check the age code of the retread.
