After noticing poor gas mileage lately, I filled my tires up and noticed 2 of them were at 20psi, one at 25psi and one at 30psi.

All tires were filled up to 45psi- a little high, but temperatures are supposed to plummet next week which will effectively lower the pressure. I figure by the time the temperatures come back up I'll have lost a pound or two and they'll settle around 40psi
