I hope someone can give me some advice.

I have a 2018 Honda Accord Touring 1.5 with 45K miles. I live in the Dallas suburbs.

At 38K I replaced all my tires with an OEM tires which was a month ago.

Last week, due to hitting a pot hole, I had to replace a tire and Discount Tire, replaced it. It’s also the place I bought my new tires. They put 36 in each tire and recalibrated the TPMS.

Yesterday, the low tire air sensor went on twice. Please note it was raining all day, and there were areas of flash flood. After the first time the sensor went off, the place I went to just put air in my tires and sensor went off.

I then took it to Firestone where the mechanic, looked at each tire for about 45 mins. The technician put the tires at 33 now.

I took the car for a test drive for 40 mins mostly Highway driving and nothing so far.

Would anyone recommend that I go to the dealership for them to look at the TPMS system?

The only times I’ve had the low tire sensor come on before was due to a nail in the tire.

I’m trying to get ahead of any issues since I drive quite a bit every day. Any thoughts, feedback, recommendations would be much appreciated. TIA!

I recommend you trash TPMS and just look at your tires. DON'T take it to a dealer. They will look upon you as fresh meat and overcharge you. If you must have it fixed, go to All Star Japanese in Addison. They service my 8th gen, are honest and reliable.

I think I’m going to see if the sensor goes off and go to All Star Japanese. I have a pretty accurate gauge so I’m going to just check it if the sensor goes off.

Do you recommend I keep using 33 vs 35. I was using 35 before. Thanks!

Pretty sure the tire pressure (cold) is supposed to be 33, so at 36 (and then driving on the highway) that probably triggered the error. When I first bought my accord the dealer had overinflated the tires so my TPMS light was going off too. After releasing air from all tires the light went off.

I’ll keep them at 33 then. Thank you!

At least for me, 35psi in the fall/winter and 33 in the summer. That being said. Any time you check tire pressure or add air. You need to reset the TPMS in the settings before driving off. If you don’t, it can throw off the system causing errors like these.

I have a 2018 Accord Touring. Over the 3+ years the low tire warning has been triggered probably 3 or 4 times, generally it is after the car has been serviced. Each time
the tire pressure was correct, 35#. Recalibrating fixes the TPMS issue, it is bothersome and should it happen more often I'll check with the dealership. With most issues I
have had with the car they do not have a clue. I find Honda dealers do not take service seriously, they take selling the car, selling the extended warranty, etc., very seriously but after that you are pretty much on your own. Perhaps it is because Honda's last so long, they know it will be a long time before you buy a new one.

Since when does TPMS react to over-inflation?

Once TPMS is properly calibrated, it only reacts when PSI drops a certain amount below the calibration level. And since TPMS actually measures tire rotational speed not PSI, it's a change in wheel rotation speed, caused when PSI is low(er), that triggers the system.

You're supposed to start a TPMS calibration and drive between 30-60 MPH for ~30 min after checking/changing PSI. Don't know about the '18, but on my '16, there's an option on one of the menus to start TPMS calibration. Sometimes, maybe a day or so later, the TPMS triggers again, which means the calibration wasn't complete. So I check PSI again and do the calibration again, with a longer drive within the 30-60 MPH range.

All i can say is that on two occasions I've found that the tires were overinflated after having the light come on - the first instance being the day after purchasing (the brand new car) from the dealer. Whether both instances were just due to the techs not calibrating the TPMS correctly and the tires just coincidentally being overinflated, i couldn't say. 🤷

The only time I had issues was on a scorching hot day where it went off twice in the same drive. Both times I just did the sensor recalibration through the infotainment when stopped at a light.

2018 Accord Manual:

Note also that slippery roads (eg, rain) can set TPMS off, especially if it's been dry for a while and rain suddenly releases the oil accumulated on the road surface...
