If you have a full-size spare under the vehicle:
1. Locate the spare tire: It's usually underneath the vehicle, accessed from the rear. You'll likely need to lower the rear of the vehicle slightly with a jack. Check your owner's manual for the exact location and instructions.
2. Locate the jack and tools: These are typically stored with or near the spare tire. Your owner's manual will show their location.
3. Jack up the vehicle: Properly position the jack under the vehicle's frame at a designated jack point (consult your owner's manual). Raise the vehicle until the spare tire is accessible.
4. Remove the spare tire: There may be a retaining strap, bolt, or other mechanism holding the spare in place. Consult your owner's manual for instructions specific to your vehicle. You may need to remove a cover or panel first.
5. Lower the vehicle: Carefully lower the vehicle after removing the spare tire.
If you have a temporary spare (donut) under the vehicle:
The process is similar to removing a full-size spare, but the spare itself is smaller and lighter.
If you have a temporary spare in the vehicle:
This is less common in a 2002 Venture but possible. It would be located either in the rear cargo area (likely under the floor), or possibly under a panel in the cargo area. Check your owner's manual!
Crucially Important:
* Consult your owner's manual: This is the most important step. Your owner's manual will have precise diagrams and instructions on how to safely access and remove the spare tire from your *specific* 2002 Chevy Venture. This is essential for safety and to avoid damaging your vehicle.
* Safety first: Always use caution when working under a vehicle. Ensure the vehicle is stable and properly supported by the jack. Use wheel chocks on the wheels that remain on the ground for added safety.
Without knowing the exact type of spare tire your Venture has, this is the most comprehensive advice possible. Always refer to your owner's manual first.
