Bicycle tyre (100) which comprises a pair of bead cores (8), a carcass structure (2) turned around the pair of bead cores (8) and a tread band (4) radially outer to the carcass structure (2); at each bead core (8) being provided: an elastomeric material filler (12) which extends in a radial direction for a first length (HI) starting from the bead core (8), a loop (15) interposed between the carcass structure (2) and the elastomeric material filler (12), turned around the bead core (8) so as to define a first flap (15a) axially outer to the elastomeric material filler (12) and a second flap (15b) axially inner to the elastomeric material filler (12), wherein the first flap (15a) extends in a radial direction for a second length (H2) and the second flap (15b) extends in a radial direction for a third length (H3); preferably, the second (H2) and third (H3) lengths are less than or equal to the first length (H1).

Bicycle tyre (100) comprises a pair of bead cores (8), a carcass structure (2) turned around the pair of bead cores (8) and a tread band (4) radially outer to the carcass structure (2); at each bead core (8) being provided: an elastomeric material filler (12) which extends in a radial direction for a first length (H1) starting from the bead core (8), wherein the first length (H1) is at least 20% of the distance (H4) measured in the radial direction between the bead core (8) and the radially outermost portion of the carcass structure (2).

In regions, divided by a tire equator, on both sides of a tread surface of a tire, the tire includes a grip area along an entire circumference of a tread, the grip area including a plurality of recessed lines, with a shape recessed toward an inner side of the tire from an outline of the tread surface, that extend from a tread edge side in a direction inclined relative to the tire equator and are arrayed in parallel, and in each region, a recessed portion defined by two lines, extending radially towards the grip area from a point positioned in a direction of the grip area from the tire equator, and a line connecting tips of the two lines.

A device for measuring a liquid level inside a tire that include two electrodes that are designed to be positioned inside the tire in such a way that they can be immersed inside the liquid that the tire may contain, and an electric circuit that is electrically connected to these electrodes. The device is designed to measure an electric property of the liquid between the electrodes while the intensity of the electric property depends on the liquid level inside the tire. The electric circuit is designed to output an electric value for the measured electric property as an output signal that can be used to calculate the level of the liquid inside the tire.

Apparatus and method for installing bicycle tires on rims, and removing the tires from the rims, both with and without tire inserts, is disclosed. The apparatus greatly eases the process of installing and removing a tire from a rim, especially a bicycle tire, and even more especially when a tire insert is used. The apparatus includes an axle that is received in and securely attached to the wheel's hub. A handle is pivotally attached to the axle and a tire removal and installation head is slidably located on the handle.

A polyurethane microcellular elastomer, a non-pneumatic tire and a preparation process and use thereof are provided. The polyurethane microcellular elastomer is obtained from a polyurethane reaction system comprising components such as isocyanate, trimethylolpropane-started polycaprolactone triol, a catalyst and a foaming agent. The non-pneumatic tire produced from the polyurethane microcellular elastomer has very strong fatigue resistance and can be used for non-motor vehicles running at high speed.

The present application relates to a high grip snow tire, which belongs to a field of snow tire, including a carcass. The carcass is provided with pattern blocks and friction blocks on the circumferential surface thereof, which are positioned on the same side with the equatorial plane of the carcass. The pattern blocks and the friction blocks are successively distributed along the circumference of the carcass, and are in mirror symmetry about the equatorial plane. The friction block includes a plurality of fixing protrusions, which are gradually sharp along the direction away from the carcass. The carcass is provided with a protection groove on the surface thereof, and the fixing protrusions are positioned in the protection groove. The present application has the effect of improving the grip.

A wheel comprising a non-pneumatic tire for a vehicle, such as a vehicle that is steerable and/or otherwise movable by leaning the vehicle (e.g., a bicycle, a motorcycle or another two-wheeled vehicle), in which the non-pneumatic tire may be designed to enhance its use and performance, including, for example, to avoid sudden failure, improve steering and/or other movement of the vehicle (e.g., when the vehicle is leaned and the non-pneumatic tire is cambered), improve ride comfort, and/or exhibit less rolling resistance.

A replacement exercise bike tire that will emulate the ride characteristics and effort of a conventional bike tire that is partially deflated. The increased roll resistance imparted by the exercise tire will enhance the bike rider's workout by imparting greater pedal effort required to ride. Multiple interconnected compartments within the tire body are filled with a high viscosity material that will displace under load as the tire rotates during use emulating a flat tire.

An inflation system for tubeless bicycle tires may include a valve, a sealant canister, a pump head, and/or a valve core adapter. The valve, sealant canister, and pump head may collectively facilitate sealant injection into a tire by a user. The valve has an external valve seat, and includes a valve body, a valve stem extending through the length of the valve body, and a retaining mechanism for the valve stem disposed interior to the valve body. The valve stem is configured to move relative to the valve body, such that a resilient seating surface disposed at a proximal end of the valve stem is displaced relative to a valve seat formed by an exterior surface of a proximal end of the valve body.
