Tire pressure on the Cobalt SS/SC with the Michelin Pilot Sport A/S 3+ tires is finicky.

If they're at 31 pounds of pressure they become hard to turn, difficult to correct, unstable in hard corners, and they grab and pull the steering wheel on every rut and bump in the road. If they're at 33 pounds of pressure, they get directionless, overly responsive, brutal over road irregularities, and the steering loses all feeling — not to mention it starts to struggle with the traction limit on hard corners — it feels like rolling on marbles.

I can feel the difference when the tires are off by a half pound of pressure. They're that persnickety when installed on this car.

I don't have very good access to a compressed air source, so keeping the Cobalt's tires running at the optimum 32 psi pressure is a real challenge.

After I got back from my last road trip, I reached my limit with it when I kept blowing breakers trying to use the only air compressor I have access to.

Since that little air compressor already blows the circuits on the only plug-in available, getting a regular compressor — even a little portable one — isn't going to work.

I need another solution.

So, I decided to pick up a cordless Ryobi 18V One+ Dual Function Inflator/Deflator to see how well it does the job.
