Is a portable tire inflator worth keeping in the car?

Yes — a portable tire inflator is very worth keeping in your car for most drivers. It’s a practical, relatively low-cost tool that can help with safety and convenience.

Why it’s useful:

• Emergency preparedness: If you notice a low tire or a slow leak, you may be able to add enough air to drive to a repair shop instead of waiting for a tow.
• Convenience: You can top off tires at home or wherever you are without relying on a gas station air pump.
• Saves money and wear: Driving on underinflated tires can reduce fuel economy and increase uneven tread wear.
• Seasonal changes: Tire pressure can change with temperature, so having an inflator makes it easier to keep tires at the right pressure.
• Extra uses: Many models can also inflate bike tires, sports balls, and some inflatable gear.

What to keep in mind:
A portable inflator is best for routine top-offs and minor slow leaks. It will not fix a major puncture, sidewall damage, or a blowout.

What to look for:
You can choose between:

• 12V plug-in models that run from your car’s power outlet
• Cordless rechargeable models that are easier to move around but need charging
