Put some air in them. Recommended tire pressure is 35psi

 

32 sounded low to me as well (used to be my old standard pressure years back) I can't remember the door jam setting, but I run mine closer to 38 (slightly over)
You are at the limit of the TPMS, all it takes is a cooler morning to trigger it. The reading from the TPMS is not the quickest at times for accurate real pressure.

 

I haven’t gotten an alert but the most my TPMS ever says is 33 psi. I checked it with 2 gauges when I put 35 psi in but that’s it.

 

The recommended Tire Pressure is 35 PSI
Most Monitoring Systems will start to alert at a 10% Loss

31 PSI is the 10% Loss..
Add air and you will not have any issues

 

I must be blind but I thought it was 36psi, I'll have to read the label again (with my glasses on - LOL). I've been running 45psi for my trip, think it REALLY helped with the mileage. Going to go back down to 35.5 when I get out of the mtn's here at work.

 

45 must be harsh.
I remember on my Gen2, if I kept it at the recommended pressure, the tires would squeal when turning on interior concrete parking lots, a few pounds made them quiet.
My dealer used to bring them down every time I brought it in, and I'd have to air up again.

 

My head is in pounds, but the truck is in metric (kpa) and I honestly don't know what my pressure reads after they are checked after the annual tire swap.
Kilometers I can understand, kpa pressure is a concept.

 

Kpa is VERY roughly 7x PSI, actually it is 6.89476x

So to go from PSI to Kpa multiply by 7
and to go from Kpa to PSI divide by 7

 

During my first year or so, I’d get an alert when the pressure deviated beyond +/- 2psi from the recommended 36psi. This past year I’ve seen it fluctuate +/- 5psi with no alerts.

 

Recommended as stated above is 35psi. Having 45psi in tires sounds rough. Also depending on how far of a drive, overinflating tires for extended periods of time can prematurely wear out the center of your tires.

 

It's a mite bouncy. As soon as this tank is done I'm going to lower it back to 36, I just did that for hwy milage on my trip, and it worked great. Still showing 18.4 on the dash and the calculated mileage is usually about .3 or more higher. Not bad for 35's. I'm not worried about it for the 2k miles I did on the trip. For my RAV4, it actually made the tire wear BETTER, because as hard as I drove it in the mtn's, running the stock 36-ish psi was causing excessive outer front tire wear from understeering and "feathering" the outer tread. As soon as I upped the pressure, the understeer went away, it was much more balanced, and I got maybe 2 extra mpg to boot. The tire wear was then perfectly even. So, I'm hoping my new CR-V does the same. I've got almost 14k miles on it and the wear looks good.

 

Check your recommended tire pressure on the front door sticker. Mine is 36

 

 

Recommended cold pressure on my 23 TB is 36psi. I don't think the relearn button does anything without the calibration tool other than beep the horn and illuminate the front drivers side head light.

 

Disagree, the relearn works, no tool required. I rotate as well as swap rims summer/winter, 4 times already, 2 sets of tpms, no issues. Admittedly, I am on the rare side, most owners need the tool on the gen3 it seems
I do have the tool and I am aware of the slight differences in all 3 generations. I have had all three.

 

op never came back to say if he fixed the issue

 

I know those batteries go dead inside the tire, I have had 2 batteries die and 1 sensor in the tire! It's not cheap either!

 

I've had great luck with mine over the years, lasted maybe 8 years or more, can't even remember.
