Slime Smart Spair Tire Repair Kit — 16 oz Sealant & 12V Inflator, Temporary 15-Min Fix for Passenger Cars

Slime 50107 Smart Spair is a compact emergency tire repair kit that seals punctures up to 1/4" and reinflates the tire — all without removing the wheel.

This all-in-one roadside kit combines a 16 oz (473 mL) temporary sealant bottle with a 12V inflator, handy inflation accessories, clear instructions and a zipped storage bag so you can get back on the road quickly after a puncture. The formula is designed for short-term emergency repairs in passenger vehicles and larger highway-capable vehicles; it’s TMPS-safe, non-toxic and non-corrosive, and refills are available if you use the sealant more than once.

How quickly will this kit get my flat sealed and inflated?

With the Smart Spair you can complete a repair and restore driving pressure in about 15 minutes using four simple steps. No jack or wheel removal is required, which keeps the process faster and safer at the roadside.

• Typical service time: about 15 minutes from start to finish
• Four straightforward steps: attach, dispense sealant, inflate, and check pressure
• No jack or tire removal required — works while the wheel is mounted
• Includes clear instructions to guide each step

What size punctures can the Slime sealant repair and how long does it last?

The sealant is formulated to plug punctures up to 1/4 inch (6 mm) in diameter and provide a temporary, safe repair. Because it’s a stopgap solution, Slime advises removing the sealant and having a permanent repair or replacement performed within the recommended window to avoid long-term effects.

• Puncture capacity: up to 1/4 inch (6 mm)
• Temporary use only: remove sealant within 3 days or 100 miles (whichever comes first)
• Safe for tire pressure monitoring systems (TPMS)
• Non-toxic and non-corrosive—designed to protect tire and rim surfaces

What comes in the kit and how do I store or refill it?

The Smart Spair kit bundles everything you need for a roadside emergency: the 16 oz sealant bottle, a vehicle-compatible inflator, inflation adapters for sports balls and other inflatables, clear instructions, and a compact zipped bag that fits neatly in most trunks. Replacement sealant bottles are available so you can restock after use.

• Included: 16 oz (473 mL) Slime emergency sealant and 12V tire inflator
• Extras: adapters for sports equipment and small inflatables
• Packaging: zipped storage bag for neat trunk storage
• Refills: sealant refills sold separately to replenish kit after use

Is this safe for my vehicle and which vehicles is it suitable for?

The Smart Spair is intended for standard passenger tires and other highway-capable vehicles for emergency use only. The formula is TPMS-safe, non-toxic and non-corrosive, minimizing risk to both tire sensors and wheel finishes when used as directed.

• Recommended for passenger vehicles and typical highway vehicles
• TPMS-safe to protect tire pressure sensors
• Non-corrosive to limit rim and tire damage during short-term use
• Not a permanent repair; see a tire professional after using

Who is this for: The Slime 50107 Smart Spair is ideal for drivers who want a compact, easy-to-use roadside solution to handle unexpected punctures without tools or tire removal. It suits daily commuters, family cars, ride-share drivers and any motorist who values a quick, temporary fix to regain safe driving pressure until a professional inspection or permanent repair can be performed.
