Note: Models R6, R8, R10, and R12 use a 20mm tube axle. Old models with 5/8” diameter solid axle will NOT fit these wheels. Models designated with “RR” such as “RR10” are older models. 5/8” axle wheels are now available with No-Flat tires.

Note: If valve stem retracts back into hub: Deflate tube completely. Firmly pinch tube and tire together with one hand while grabbing hub with other hand. Turn hub in appropriate direction until valve stem pops completely back through hole. Reinflate tire to 30 psi. Check pressure approximately every 3 months.

NO-FLAT TIRES: are foam filled, giving a pneumatic-like ride requiring no air.

Note: All models since 2001 use 12mm (0.5” threaded stems). Older models used a 7/16” (ll mm) threaded stem but often the new casters will still fit if the hole in the front axle has enlarged a bit because of wear. If necessary, the hole can be drilled to 31/64” ideally or even 1/2” will work.
