Inner tube, standard duty, 4.00-19"

Standard duty tube for all Urals with 19" wheels.

IRC has been our house brand of tubes in the repair shop since we opened in 2011. They're good. We like them.

Officially listed as sizes 4.00/4.50-19 and 110/90-19.

IRC declares these to be 100% butyl rubber. Helps with keeping your tire pressure stable for longer. But you still still check them at least every month. (And don't skip out on airing up your spare wheel, if you have one!)
