SCHWALBE SX-R Folding Tires

SCHWALBE SX-R folding tires for BMX and compatible small-wheel bicycles. Choose 42-406, 47-406 or 30-451 by the exact ETRTO size. The supplier lists a 67 EPI casing, a low-resistance tread and approximate weights from 200 to 295 g.

Choose the Correct Tire

Each option supplies one tire. The 406 mm and 451 mm bead-seat diameters are different and are not interchangeable, even though both may be described as 20 inch. Check the ETRTO marking on your existing tire and rim, then check tire width and frame clearance.

Specifications by Option

Tread and Construction

The SX-R has a low-resistance central tread with textured shoulder areas, as shown in the close-ups. The supplier identifies these folding tires as part of the Performance series, for BMX and small-wheel applications. Preserve the tread orientation and installation requirements specified on the supplied tire.

Installation and Contents

The listed pressure ranges vary by option. Follow the lower applicable pressure limit specified by the tire and rim. Product weights are approximate. Boxes, folded tire views and mounted-wheel photographs illustrate the product; one selected tire is supplied, with no wheel or inner tube.
