Patent number: 10065458Abstract: A vehicle wheel includes a rim, an inflatable tire, a grounding tire, and a safety unit. The rim includes two tire engagement portions spaced from each other in a longitudinal direction. The inflatable tire is mounted around the rim and includes an inner annular bottom wall and two inner annular sidewalls respectively on left and right sides of the inner annular bottom wall. Each inner annular sidewall includes an inner side having a lip pressing against one of the tire engagement portions of the rim. The grounding tire is mounted around the inflatable tire and includes an outer annular bottom wall capable of rolling contact with the ground. The safety unit is sandwiched between the inflatable tire and the grounding tire to couple the inflatable tire and the grounding tire together, permitting synchronously rotation of the inflatable tire and the grounding tire while increasing the anti-slipping effect.Type: GrantFiled: January 14, 2016Date of Patent: September 4, 2018Inventor: Ching-Huang Tsai

Patent number: 8397772Abstract: The emergency tire support device for a low air pressure tire includes an elongate belt formed by three layers of material that protects and supports a deflated tire. The belt wraps around the tire and is secured thereto by fasteners. The three layers include an outer layer of cloth, an inner layer of plastic, and an intermediate layer of cloth. A plurality of tacks extends through the inner layer, and the intermediate layer sandwiches the head of the tacks between the inner and intermediate layers. The tacks pierce the tread area of the tire as the tire rolls over the belt during installation, causing the belt to automatically wrap around the tire. The tacks also prevent slip. The inner and intermediate layers are stitched onto the first layer to form a plurality of longitudinal pockets. The pockets are filled with scrap rubber.Type: GrantFiled: June 27, 2012Date of Patent: March 19, 2013Inventor: Husain S. A. Faridoon

Patent number: 8162016Abstract: The modular tire chain apparatus provides for ease of installation due to connecting modules that allow a user to assemble the apparatus on a tire and wheel with greater ease than having to struggle with a continuous tire chain. A further advantage of the modules is that any number of modules needed to surround a tire and wheel are easily attached together, thereby providing a substantially universal fit to a plethora of tire sizes. And, the tie strap with spring with hook aids in securing the modules to a tire. Further the ties are secured, one to the other and to the outer members. The ratchet lock further ensures snug fit of the apparatus. The inner cable, outer cable, inner members, outer members, and cross members are available in rubber coated finish, thereby avoiding potential vehicle and wheel and tire damage.Type: GrantFiled: November 9, 2009Date of Patent: April 24, 2012Inventor: Joe H.
