Description: A spare wheel is an extra wheel carried in a vehicle, typically in the trunk or under the chassis, intended to replace a flat or damaged tire temporarily. It serves as a backup in case of emergencies, allowing drivers to continue their journey until the original tire can be repaired or replaced.

Description: A TPMS valve, or Tire Pressure Monitoring System valve, is a component installed on a vehicle's tire rim that monitors the air pressure within the tire. It sends real-time pressure data to the vehicle's onboard computer, alerting the driver if tire pressure drops below a certain threshold, helping to improve safety and fuel efficiency.
