WITSTEP Spare Tyre Trash Bag for 30–40 in Tyres — 30‑Gallon Waterproof Off‑Road Storage with MOLLE & Quick X-Straps

The WITSTEP Spare Tire Trash Bag is a heavy-duty, waterproof storage and waste solution that fastens to 30"–40" spare tires to keep offroad vehicles tidy and organized.

Designed for off-road adventurers, overlanders, and weekend campers, this spare tire-mounted trash bag converts an otherwise wasted space into a rugged storage hub. Constructed from reinforced 1680D canvas with a waterproof interior coating, the bag combines large capacity with tool-organizing features like mesh pockets, MOLLE straps, and a zippered top pocket. Quick-install X-straps and solid buckles secure the unit to spare tires while reflective strips and drainage ports add safety and practicality during wet conditions.

How large is the WITSTEP Spare Tire Trash Bag and what fits inside?

The bag measures 31.5 x 21.5 x 9.2 inches and holds up to about 30 gallons, giving you generous room for trash, muddy gear, or rescue supplies. A zippered top pocket keeps dirty clothes or shoes separate, while four exterior mesh pockets and MOLLE webbing organize tools and accessories.

• Internal capacity: roughly 30 gallons for waste or gear
• Top zip pocket for shoes, gloves, or small garments
• Four mesh pockets for bottles, gloves, or small tools
• MOLLE straps for attaching carabiners, pouches, or recovery gear

Will it fit my vehicle’s spare tire and stay secure on rough roads?

This spare tire bag is built for universal compatibility with 30"–40" AT/MT tires, making it suitable for most trucks, SUVs, and many off-road vehicles. Heavy-duty X-straps and robust buckles keep the bag anchored during bumpy drives, and the double-stitched shoulder and buckle areas improve longevity under load.

• Fits 30"–40" spare tires (AT/MT styles)
• High-quality X-strap system for a snug fit
• Durable buckles and double-stitched stress points
• Designed to remain secure on rough terrain

How does the design protect contents from weather and odors?

The bag uses a 1680 Denier reinforced canvas shell with a waterproof interior coating to resist rain, mud, and splashes. Two nylon covers offer additional protection at attachment points, reflective strips enhance visibility in low light, and bottom drainage holes let water escape so the interior stays dry and odor-resistant.

• Waterproof interior lining prevents seepage and stains
• Nylon covers reinforce high-wear attachment areas
• Reflective strips increase night-time visibility for safety
• Two drainage holes at the base prevent standing water and odors

How easy is it to install and maintain?

Installation is straightforward: thread the X-straps around the spare tire, tighten the buckles, and you’re done—no tools required. When full, the bag detaches quickly for emptying or cleaning; the tough materials wipe clean or hose off as needed for simple upkeep.

• Tool-free setup with adjustable X-straps and quick-release buckles
• Removes easily for emptying or laundering spills
• Wipeable canvas and waterproof interior for simple cleaning
• Designed for repeated use in harsh conditions

It’s useful for anyone who needs a durable, weatherproof container for trash, muddy boots, recovery gear, or roadside supplies—especially when vehicle interiors must stay clean and organized during extended trips.
