Seal tires: the perfect filling and never again a breakdown?

When a car tire breaks it is always associated with a lot of work, trouble and some dangers. Many drivers know what a flat tire means. With a lot of luck, the vehicle can be stopped in a safe place if nothing works. But a lot can go wrong even if there is a spare or spare wheel in the trunk. Bad tools, fiddly jacks or stuck screws on the wheel make the driver desperate. Many manufacturers offer one ex works Roadside Assistance Setthat can be stowed in the trunk. This means that mobility can also be done on its own not always guaranteed. A repair attempt is rarely successful. Sometimes the compressor pressure is insufficient or the sealant cannot be distributed as desired. In addition, repairs are very dangerous for drivers at the edge of the road.

Seal technology tires!

But there is a solution: Manufacturers such as Pirelli, Continental, Goodyear, Michelin or Hankook have put tires on the market that have a hole in the tread repair yourself be able. In contrast to tires with run-flat properties, which are caused by a reinforced side wall The self-sealing models could theoretically make it possible to travel to the next workshop at 80 km / h continue to be used. The VW Aerton and the VW Passat are fitted with such tires at the factory. The miracle tires can be used for many rims, so that they can be easily retrofitted. In terms of price, however, the tires are over 20 percent of the normal tires that are not equipped with this technology.

Sealing by sticky mass

The self-healing principle is called by the manufacturers Seal technology designated and is simple. One sticky and dimensionally stable mass is applied to the inside of the tire. When a foreign body sticks through the tire, this mass is placed directly around the penetrating body. When the nail or shard is pulled out, the air pressure inside the tire will hold the mass pressed into the hole. The opening is thereby sealed. According to the manufacturer, this method works for holes with a size of up to five millimeters. Well-known tire types with Seal technology are:

• Continental SportContact 5 with ContiSeal
• Hankook Ventus Prime2 Sealguard
• Pirelli Cinturato P7 Seal Inside

not a panacea for damage of any kind

If the Side wall For example, if it was damaged by a sharp curb, the system works not. The sensitive side walls must be left out, otherwise the tire will lose its own damping. The tire would be too heavy and the ride would be very uncomfortable. And the self-sealing tires easily weigh 1,4 to 2,2 kilograms More than conventional models. This is not only felt by sensitive drivers. the unsprung and rotating masses are essential greater. The rolling noise is for it more subdued. As a rule, however, no loss of grip or driving characteristics is to be expected. Braking maneuvers on wet roads should not have any disadvantages.

the journey ends in 90% of the cases not

A particular advantage is that nails and screws lose their fright. Various tests on the internet show that by means of special devices and the insertion with nails up to four millimeters thick or three to four millimeter large wood screws save permanent damage remained. Even a sensitive, active tire pressure control system hit the test no alarm. The air pressure also remained constant. Even on the following day, no air loss could be determined. By the way, all manufacturers recommend that the foreign body should be removed. This prevents the foreign matter from unnecessarily widening the hole.

Check tires anyway!

No restriction in driving behavior, no warning message and no loss of air - drivers could quickly succumb to the temptation to use the tires up to the wear limit continue to use. That would be technically possible, but not allowed because the tire is officially considered damaged. The foreign body eventually entered the carcass and likely caused damage. And you certainly want that not find out at 250 things on the highway!

Every damaged tire should therefore be checked by a specialist as soon as possible. Paragraph 36 of the Road Traffic Licensing Regulations states that a tire can be repaired, but a repair is possible only is permissible after dismantling and thorough testing. The legislature cannot do much with the new technology. In the opinion of the Vulkaniseur-Handwerk and the Federal Association of Tire Trade, the introduction of the preventive sealant in liquid form is not permitted. For this reason, Seal tires are allowed not as puncture-proof and self-healing to be advertised. And the recyclability and the additional cost of materials are also an environmental issue.
