Make sure you check your tire pressure.

The day before i left on my epic cross country trip, I, of course, checked my tire pressure.

3 of the 4 tires were still spot on, but the right rear was way low. I pumped it up. However, bad me, I neglected to do so every day. Two days ago, I checked it and it was down to 40#.

On this trip, I'm carrying a 1.5hp, 3 gal air compressor. I pulled it out and aired the tire up to 50#.

When I checked today, it was holding at 50#.
