Concern
The tire pressure light comes on with the first cold snap of the season.
Cause
Air contracts as it cools. Tire makers including Firestone and Goodyear estimate a loss of about 1 psi for every 10-degree drop in outside temperature. A tire that was already a few pounds low can cross the warning threshold overnight.
Correction
Check the pressure while the tires are cold and set it to the number on the sticker inside the driver's door, not the maximum printed on the tire. A portable inflator turns that into a five-minute job in your driveway.

Pick it if

You want an inflator that always works, including after weeks in a freezing car, or you have larger SUV or truck tires.

Skip it if

You'd rather not open the hood and clip onto the battery. A cordless inflator is quicker for small top-ups.

Fanttik X8 Apex

Max pressure
150 PSI
Auto shut-off

Up to 16 tires without a cooling break

Pick it if

You top up car tires at home and want something small that you can set and walk away from.

Skip it if

It would live in a car parked outside all winter. Like any lithium tool, it loses capacity in the cold and can be flat when you need it.

Skip it if

You'd need to buy into the battery system. The $79 kit costs more than the Fanttik, and the VIAIR is better for winter.

From the service counter

  • Check pressure in the morning, before you've driven more than a mile or two. Warm tires read high.
  • Use the number on the driver's door sticker or in the owner's manual. Front and rear pressures can be different.
  • Built-in gauges vary. A separate tire gauge is cheap and a good way to double-check.
  • If one tire keeps losing air faster than the others, have it looked at for a nail or a leaking valve stem. That's usually an inexpensive fix if it's caught early.
  • If your car has a spare, check it too. It loses pressure in the cold like the others.
