A 20″ premium rubber inner tube with industry standard schrader valve. Designed accordingly to fit modern day BMX tire sizes.
20 x 2.10-2.45”
The Williams tire combines the best of both worlds, with a smooth continuous centerline tread that rolls super-fast and super grippy micro-knurling across the side treads. The 2.5” width adds stability and softens hard landings, while still fitting in most modern frames. Nathan Williams tested and approved.
