how do i check if flat tire warning's real?

I got a flat tire warning yesterday and pulled over and couldn't see anything wrong with any of the tires. I checked the air pressures and they all seemed pretty normal. I've never had any experience with runflat tires before, so I'm unsure as to if any are actually flat. Should it be really obvious to the eye if one's flat? Or any simple way I can check it on my own? Thanks!

Very hard to see if a runflat tire is "flat'

Best way is to check with a pressure guage

You said, ."I checked the air pressures and they all seemed pretty normal." I am not sure what you mean by "pretty normal". Did you set the pressures equally from side to side? If so and if you re-set the TPM, you should be good to go.

I know this feeling. From what I was told which seems right. If you have pressure in all your tires, you didn't catch a flat fill up the front tires to 32 psi and the rear to 36psi, that's what my jam says. If it doesn't come on again your fine, if it does check the tires to see which one had the drop in pressure it you might have a puncture.
