Is your air pressure set to spec? I know when air get warm, it expands causing the pressure to increase.. I was told its best to check air pressure whren the tire are cold, for that reason.
Others have used nitrogen, as it remains stable, and does not change with temperatures...also help gas mileage by appox. 2% .....hope this helps

I air my tires to 36 psi. Honda says 32 when cool. Your tire pressures must be low.

I filled mine to 32 psi when it was cold (40's). When it was warmer (80's), my psi measured around 35. If TPMS is coming on, you need to add air. You're probably around 24psi in the morning and 26psi in the afternoon...my TPMS came on for one tire at 24psi, but the other 3 were 25psi and did not activate the TPMS.

ACTUUUUUALLLY, it was 42* this morning in HOUSTON. So it was probably the same or a little cooler in big D.

Just add a little more.
Below 25psi, the light comes on, you don't want to be driving that low anyways. effects MPG. I'd add it up to 30 when cold. It'll probably warm up to 32psi, if that.

Did a wheel light come on, or just the "TPMS" indicator on the left side of the speedometer? Could you have a TPMS failure?

I run 40PSI all the time.....get's me 23MPG if I keep it under 60MPH!

You know the tires are rated at 35PSI MAX don't you? I suspect I'd get 23MPG keeping in under 60MPH at 32PSI if I'd actually drive that slow. I got nearly 22MPG with just an hour of 1 tank at 55 to 60 MPH.
