AR-PRO (2-Pack) Universal 145/70-6 ATV Inner Tubes - 450/530-6 Heavy Duty Inner Tubes Compatible with 90cc 4-Wheeler ATV, Go-Kart, Mini Chopper, Lawn

●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. A Note on Compatibility: Please double-check the size of tires on your dirt or pit bike. Though this size of inner tube is commonly used on 4-wheel ATV, mini choppers, and go-karts, it’s not the only size. The same is true for lawnmowers, hand trucks, and wagons. Check the size stamped on your inner tube or on the sidewall of your vehicle/equipment’s existing tires. Either of the following tire sizes should be on the sidewall: 145/70-6, 450/530-6, 4.50-6, 5.30-6, and 5.30/4.50-6. These replacement inner tubes will fit tires with an outer diameter of 14 inches, a width of 3.5 inches, and a rim size of 6 inches. 145/70-6 ATV Inner Tube Features These inner tubes are made of a premium butyl rubber compound and manufactured to be 4x thicker and more durable than average inner tubes in the market today. Each tube is wear, rot, and deterioration resistant. It won’t easily crack or dry rot even when stored away for months on end. And as it is evenly molded, it won’t become thinner in some places, inflate unevenly, or lose its structural integrity after a repair. Distributed sealant all over the inner tubes allows for instantaneous sealing of small punctures - all without weighing the inner tubes down. All these characteristics enable these rear inner tubes to provide optimum elastic damping, minimizing vibrations and impacts. Most importantly, this ensures optimum air retention so you can ride on for days without the need for reinflation!
