Need to replace the worn-out tires on a kid's bike, BMX, or a small cruiser? This YUNSCM 2-pack has you covered with both tires AND tubes. You get TWO 16-inch bicycle tires in the size 16x2.125. They have a block-shaped tread pattern that gives good traction for everyday riding on pavement and light dirt paths. They're made from a durable rubber compound that promises good wear resistance. These are folding tires, which means they're not stiff like some – you can actually fold them up, making them easier to store or carry as a spare on a long trip. The set also includes TWO heavy-duty 16-inch inner tubes with a 32mm Schrader valve (the same as a car tire valve). The tubes are sized 16x1.75/2.25, so they'll work perfectly with these tires and a range of other 16-inch tire widths from about 1.95 to 2.15 inches. This is a great value set for replacing both wheels on a single bike or doing two different bikes. Just remember, you'll need tire levers and a pump to do the installation. A solid, affordable refresh for a 16-inch wheel bike.
