●UNIVERSAL FIT 145/70-6 ATV INNER TUBES - Affordable and convenient, this pack of 2 inner tubes is a suitable replacement for not only 145/70-6 size inner tubes but also for 450/530-6, 4.50-6, 5.30-6, and 5.30/4.50-6 tires.

●450/530-6 INNER TUBES COMPATIBLE WITH 90CC 4-WHEELER ATV - This is one of the most common inner tube sizes for 90cc 4-wheeler ATVs, mini choppers, go-karts, hand trucks, dollies, trollies, wagons, utility carts, lawnmowers, wheelbarrows, generators, snowblowers, wood chippers, air compressors, yard trailers, and other wheeled equipment.

●HEAVY DUTY INNER TUBES - Inner tubes have one weakness: punctures. Not only would punctured inner tubes deflate, but they can also explode and cause damage to your bike and injury to you, the rider. Our line of replacement inner tubes have self-sealing properties that prevent explosive punctures by creating instantaneous air-tight seals around puncture holes.

●TR13 STRAIGHT VALVE STEM - This is the standard rubber-covered straight stem valve used on most lawn/garden and utility inner tubes. It is rated for a maximum of 60 psi. It has a 1.5-inch offset from the center of the tube. With a length of 1.38 inches and around .453 inch wide (fits 1/2-inch rim holes) and can be used on .625-inch rim holes with the use of B6 rim bushing.

●ENJOY AN IMPROVED RIDING EXPERIENCE - Made from butyl rubber compound, these inner tubes provide better elastic damping than other types of inner tubes. And as they are also thicker than average inner tubes in the market, the vibration dampening action doubles, enabling the inner tubes to work effectively in tandem with the bike’s ssuspension system to provide you with the most comfortable ride.
