Eli5: Why do bicycles have inner tubes in the tire while cars don’t have them?
In: Engineering
Car tires are typically tubeless setups, where a tight fitting tire and rim combination is used (sometimes with a sealant liquid) and held in place with air pressure
Tubeless bike tire setups are available, but generally cost more (and there are sometimes issues of incompatible standards) and are less widely available.
(Also tubeless bike tires can be a pain to install or repair without the proper tools )
