Loading system

Designation Runflat carry tires that are able to continue driving even when the defect or loss of pressure. The so-called driving range used automobile tires and replaced them spare wheel or tire repair kit. Runflatové tires but have higher cost and their operation is also costly.

The principle function of loading system is based on the idea of using reinforced sidewall tires. While a normal tire loses pressure, simply collapse under the weight of the vehicle. tire bead can then strip off the rim, or it can break through walls . After a few kilometers away is the common tire completely destroyed. In contrast, reinforced sidewall loading system keeps the tire on the rim even with complete loss of air. Reinforced side panels bear the weight of the vehicle and at a reduced maximum speed (typically 80 km / h) ride lasts from 100 to 1000 km (see advertising data producers).

History
The first patent for a puncture-resistant tire was already written in 1892 by John F. Seiberling. Re-discovered and was carried out until the arrival of tire RunOnFlat (ROF) developed by Goodyear in 1978. For mass production, however, found application in 1994 with the arrival of a new model Chevrolet Corvette . In 2004, Goodyear introduced the first tire bearing RunOnFlat for series production, hence the folk name "ranflety". Today offers a driving range of tire brands, unfortunately, each holding their signs and motorists that complicates life.

The system tire pressure monitoring
Because runflatové tire pressure after the loss simply continue driving without a less experienced driver noticed a possible defect, the use of tire-type loading system requires the presence of airborne system TPMS (Tyre Pressure Monitoring System Tire). This system gives the driver know that the tire requires servicing.

What you did not know
With stiffer sidewall of the tire ride with Runfletovou harder than using a traditional tire. Runfletové tires also have more weight and rolling resistance, increasing fuel efficiency of cars. What is important is the financial aspect. Runflatové rubber are some 1000 crowns more expensive than traditional tires. Additionally, manufacturers do not recommend them for any repair of the defect. Due to differences in wear replacement is often in pairs. Also changing of the tires is quite challenging because they have a very rigid sidewall . A machine that tire zouvat must work very carefully to avoid damage to the casing feet . The machine does not have any extra rubber, so the changing of Runflatů is slightly more expensive.
