New BYD Sealion 7 Spare Tire Storage Box Adds a Spare Wheel Without Eating Trunk Space

Guangzhou, China — September 2026 — Maremlyn has rolled out a model-specific spare tire storage box for the BYD Sealion 7 / Sealion 07. Developed after extensive market research, the box gives EV owners a proper place to carry a spare wheel and tools — without giving up usable trunk space.

The real problem: EVs have no spare tire, but owners still want one

Most new energy vehicles — the BYD Sealion 7 included — leave the factory without a spare tire, while almost every petrol car still ships with one. Many EV owners still want the reassurance of carrying a spare wheel, but the car gives them nowhere to put it. The only obvious option is to drop the tire and tool kit into the upper trunk — which eats into cargo space and lets a loose wheel rattle and clutter the back.

After that research with owners and dealers, Maremlyn set out to close the gap with a dedicated, model-specific spare tire storage box for the BYD Sealion 7 / Sealion 07 — a proper home for a spare wheel and tools that doesn't cost owners usable trunk space.
  

 

What the box solves

Custom-molded for the Sealion 07 rear trunk spare tire position, it sits flush with no gaps or rattle and holds a full spare wheel plus tools in the space the car already reserves — not on top of your cargo. Core selling points:

• Seamless, model-specific fit — molded to the actual trunk floor, not a universal shell.
• Waterproof, dustproof hard shell — keeps tools and repair kits dry and clean.
• Large capacity with compartments — inflator, tow rope and first-aid tools stay separated and easy to find.
• Impact-resistant and plug-and-play — stable under load, no drilling or modification, easy to lift out and clean.

Why dealers, importers and wholesalers should stock it

• Fitment risk kills margin. Universal parts drive returns and warranty claims; a part molded to the Sealion 7 floor pan prevents "it doesn't fit" complaints before they happen.
• Complete-kit bundling. Pairs with floor mats, trunk mats, skid plates and cargo covers, letting distributors build higher-value bundles from one supplier.
• Factory-direct, stable supply. A manufacturer (not a trader) with four production bases, so restocking stays predictable.
• Protected design, custom branding. 300+ design patents across China, Thailand, Japan and Australia, plus custom logo support.

FAQ

Does it fit both the BYD Sealion 7 and Sealion 07? Yes — it is custom-molded for the rear trunk spare tire position. The two names refer to the same vehicle in different markets, so fitment is identical.

Does the BYD Sealion 7 come with a spare tire? Most EVs, including the Sealion 7, ship without one, while petrol cars still come with one. This box gives you a dedicated spot to carry a spare wheel and tools without taking over your trunk.

Will it rattle, need drilling, or let in water? No. The molded shell sits flush with no gaps or rattle, installs with no drilling or modification, and keeps out mud, rainwater and dust.

Can I order in bulk with my own logo? Yes — it is available for wholesale with custom logos. Contact the factory for MOQ, pricing and lead time.
