Tire Pressure Light Prob

[Chalk Outline]

Yesterday morning my low tire pressure light came on when I started up. I stopped on the way to work and added air to all 4 tires, but the light stayed on. Coming home the light was off. This morning back on and has been on all day. I checked the pressure and have 35 lbs all round. Any ideas on what to try next?

Did you check the spare too?

Pump your spare up to 45psi and you'll be fine for another six months or so.
