Slime Smart Spair Ultra Flat Tire Repair Kit 50158 — One‑Button Inflator & Sensor‑Safe Sealant

Slime Smart Spair Ultra (50158) is a one‑button emergency tire repair kit that seals punctures and reinflates car or trailer tires in about 10 minutes.

When a sudden flat interrupts your drive, the Smart Spair Ultra offers a compact, portable alternative to changing a wheel or waiting for a tow. This kit combines sensor‑safe repair sealant with a built‑in inflator and an easy‑read pressure dial that runs from a vehicle 12‑volt outlet. Designed for quick roadside fixes, it’s intended to get you moving again fast while you decide on a permanent repair.

How does the Smart Spair Ultra fix a flat so quickly?

The kit pairs an aerosol‑style sealant with a powered compressor to both plug small punctures and bring tire pressure back up without tools. You attach the hose, press the single repair button, and the system meters sealant while the compressor restores pressure.

• Includes 15 oz of Slime sensor‑safe emergency repair sealant.
• Integrated inflator runs from a 12‑volt accessory outlet.
• One‑touch operation—no jack, plug, or tire removal required.
• Designed for temporary repairs until a professional service is available.

Will it work with my vehicle and TPMS sensors?

Slime specifies this formula as safe for most tire pressure monitoring systems (TPMS), making it suitable for many passenger cars and trailers. The kit’s pressure gauge reads 0–60 psi so you can confirm inflation matches your vehicle’s recommended pressure.

• Sensor‑safe sealant minimizes TPMS interference.
• Pressure gauge with 0–60 psi range for typical passenger tires.
• Compatible with cars, light trucks, SUVs, and trailers within inflation limits.
• Not intended as a permanent puncture solution—return to a shop for inspection.

How long does the repair last and what limitations should I expect?

The Smart Spair Ultra provides a temporary, drive‑able fix designed to get you safely to a repair facility. It effectively seals many common punctures in the tread area but is not a substitute for a professional tire replacement if damage is severe.

• Typical fix time: about 10 minutes from start to usable pressure.
• Best for punctures in the tread, not sidewalls or large tears.
• Sealant acts as a temporary repair; have the tire inspected soon after use.
• Keep kit accessible in the vehicle for roadside emergencies.

Who is this for: Drivers who want a fast, compact roadside solution for common punctures—commuters, families, RV and trailer owners, and anyone who prefers a quick repair over changing to a spare. The Smart Spair Ultra is geared toward users seeking an easy, sensor‑safe way to reseal and reinflate tires so they can reach a service center safely and without heavy tools.
