Will a Car's Spare Tire Float in Water?

[JordanLee]

If the inner tube contains sufficient air to displace a mass of water greater than the spare tire's own weight, it will float. Below are relevant details: Definition: A spare tire refers to an emergency replacement tire for passenger vehicles, typically matching the specifications of the original tires. However, some vehicles may use specially colored wheel spare tires, compact spare tires, foldable spare tires, or run-flat tires to remind owners to promptly inspect and replace faulty tires. Classification: Full-size spare tire: This type matches the exact specifications of the vehicle's four main tires and can temporarily replace any damaged tire. Non-full-size spare tire: These spare tires have slightly smaller diameter and width than standard tires, serving only as temporary replacements for non-drive wheels with speed limits not exceeding 80km/h.
