Learn how to mount a spare tire storage bag on your Jeep Wrangler CJ, YJ, TJ, JK, JL, or JT. Step-by-step instructions with common mistakes to avoid.

Quick answer

Mounting a spare tire storage bag on your Jeep Wrangler (CJ through JT) takes about 15 minutes with basic hand tools. The key is to position the bag so it doesn't block the rear camera or license plate, and to secure all straps evenly to prevent flapping.

Why a spare tire bag makes sense for your Jeep

A spare tire storage bag turns unused space on your rear door into organized storage for recovery gear, air hose, straps, or small tools. The RT-TCZ multi-functional bag fits CJ, YJ, TJ, JK, JL, and JT models because it uses adjustable straps rather than a model-specific bracket. That same flexibility means you need to take a few extra seconds to center the bag properly.

One trade-off: the bag adds a few inches of depth behind the tire, so check that your rear hatch still opens fully. On JL and JT models with the factory backup camera, test that the bag's lower edge does not block the camera lens.

Step-by-step installation

1. Position the bag on the spare tire: Place the storage bag flat against the back of the spare tire, centered on the wheel. The bag's straps should hang evenly around the tire's circumference. If your Jeep has a rear camera, hold the bag a few inches lower than center so the top edge doesn't block the lens. Common mistake: mounting the bag too high, which blocks the camera on JL and JT models.
2. Thread the straps through the wheel spokes: Feed each strap through the nearest wheel spoke opening, from the back of the tire toward the front. Pull the strap until the bag is snug against the tire surface. Do not tighten any strap fully yet. Checkpoint: make sure no strap is twisted. A twisted strap will loosen as you drive.
3. Tighten all straps evenly in a star pattern: Starting at the top strap, tighten it about halfway. Move to the bottom strap, then left, then right, then the diagonals. Repeat the pattern until all straps are firm. The bag should not shift when you push on it. Common mistake: tightening one strap all the way first, which pulls the bag off-center and causes uneven wear.
4. Secure loose strap ends: Tuck or tie off any excess strap length so it does not flap in the wind. Some bags have Velcro keepers; if yours does, wrap the excess around the tightened strap and secure it. Checkpoint: loose strap ends can slap against the paint and cause scratches over time.
5. Test clearance and camera view: Open and close the rear hatch to confirm the bag does not hit the bumper or the tailgate hinges. Sit in the driver's seat and check the rearview camera image (if equipped). Adjust the bag position if needed. Final check: a bag that rubs on the bumper will wear through the fabric in a few months.
