Got a kid who's rough on bike tires? This replacement set has you covered. It includes TWO 16x2.125 inch tires (that's the size - fits most 16-inch kids' bikes, BMX, and small MTBs) PLUS two matching inner tubes with Schrader valves (the standard type). Also comes with two tire levers to make installation easier. The tires are made from durable rubber with good tread for traction, and they're folding beads, so they ship compact. The inner tubes are high-quality too. Important note: these tires come folded in the package, so you'll want to unfold them and let them sit for a day or two before putting them on the rim - they'll shape up nicely. Check your current tire width (should be between 1.95 and 2.125 inches) to make sure they fit. Perfect for when your little one's tires are worn out, punctured, or just need an upgrade. Makes bike maintenance a breeze. Keep a set in the garage for the next flat tire emergency. Get 'em rolling again safely!
