Run-flat tires use a "side reinforcement" design, where the sidewalls of the tire are reinforced with "side reinforcing rubber," which supports the load when the tire loses air pressure. This is a structure commonly used for run-flat tires for passenger cars.

Furthermore, when air pressure is lost, the tire deforms and generates heat. Therefore, low-heat-generating rubber is used for the bead filler, which strengthens the bead area and reduces heat generation. Furthermore, a thicker bead is used than usual to prevent the tire from coming off the wheel in the event of a puncture. Various technologies are used to enable driving even with a puncture.

Please note that run-flat tires have a slightly different structure than regular tires, so special equipment is required when replacing them. In order to safely and reliably replace your run-flat tires, we use the following:Run-flat compatible tire changer "GA600S-LIMIT'is introduced.
