Schwalbe Smart Sam Tyre

The Schwalbe Smart Sam 20-inch tyre is a tube-type replacement for bikes with 20-inch wheels, ideal if you need to replace a worn tyre without changing the rim. It has a wire bead and weighs 435 g. The maximum pressure is 4.5 bar (65 PSI) and the maximum load is 65 kg: observe these limits when inflating and riding the bike.

The tread is HS624 in the K-Guard version, with SBC compound and a thread density of 50 TPI. When choosing, the most precise reference is ETRTO code 47-406: compare it with the code printed on your current tyre, rather than relying solely on the designation 20x1,9 or 20x1.85.

Schwalbe was established in Germany in 1973 by Ralf Bohle, with roots in the family business founded in Bergneustadt in 1922. Today it is based in Reichshof and makes bicycle tyres and inner tubes. Its name means “swallow” in German and translates Swallow, the name of the first tyres imported from Korea.
