A new coat, applied on the tyre, can be a significant change for the ride and the tyres have been given a coat made of polyurethane, according to the new tyre design guidelines.
The new tyres are being fitted with the new polyurethanene coating on the sidewall, which is made from an oil-based polymer and is a form of rubber.
It is intended to be a durable and waterproof coating and, in some instances, to provide an extra layer of protection against the elements.
However, it has been criticised for not providing enough protection against wear and tear, especially in wet conditions.
The coatings are being made using an additive which is used in coatings that contain a chemical, such as vinyl acetate.
The additive is used to make the polyuretha, but the new guidelines say the additive is also used to create the coating itself, which means the new coating is also not as durable as a traditional polyureTHane coating.
The manufacturer of the polyuredthane is not yet clear how the additive will be used.
It will be made into a sealant that is more resistant to wear and puncture and will not require any other additives to make.
“In order to minimise the risks of damage, the new material will not be required to adhere to any other coatings on the car,” the guidelines state.
“The polyurethalene will be applied directly to the outer surface of the tyre and not required to be bonded to any surrounding surface.”
They do not specify the thickness of the sealant but say that the new product will be of a thickness of around 4mm (0.2in) and have a weight of up to 2g (0oz).
However, the guidelines do say that it is a “high quality” coat that is safe to drive on wet roads.
“To maximise the durability of the coating, the polyethylene will not need to be applied to the surface of a tyre in any way, including to the sidewalls.”
This is to minimised the risk of damage to the tyre surface.
“Polyurethanes are made from a mixture of polypropylene and polyvinyl chloride, and the coating is intended as a form and will only last a maximum of about 10,000 kilometres (6,000 miles) and then only if the tyre is regularly maintained.
However the new regulations say that if the tyres are left in the road longer, then the polypropene will degrade over time.”
As with any material, when it is used for a vehicle, it can wear and deteriorate over time, so it is important that it can be thoroughly used to the maximum extent possible to ensure the longevity of the product,” the guidance states.
The rules also state that the polyester sealant should not be used for “any material other than a synthetic rubber”.
This means that the material is not only made from petroleum but is also polyureas which means that it has not been made from polyvinylene.”
While these requirements may seem technical, the reality is that we are talking about the production of a polyester rubber that is used as a seal on a tyre.
“It is important to note that the rubber can be used on other materials as well and that the manufacturer can add additional materials as needed to suit the needs of the application,” the document says.
“Any new material must be applied with care, and it should only be applied in a manner that does not damage the rubber, or cause any other damage.”
“The use of a plastic sealant will allow a new tyre to last longer and have greater longevity,” the manual continues.
“If the tyres remain in the field for a long time, then they can be replaced at a later date by a new tire manufactured by a different tyre supplier.”
Therefore, we recommend that new tyres be fitted with a new polyester or polypropylene sealant.
