Hello,

I noticed for the past month I get a message on my screen saying tire pressure low.
Also is there a way on the screen which tire it thinks is low?

Hello,

I noticed for the past month I get a message on my screen saying tire pressure low. I couldn't read the stock tires pressure min and max but I put in a couple of pounds on each so they all read 32lb. I still get the error message. Anyone know what the stock 17" wheels on a 2018 accord should have for proper pressure?
 
Even if you had the recommended tire pressure you need to re-calibrate the TPMS system each time. See below.


No, the 10th gen accords use an Indirect TPMS System. See below.

"Indirect Tire Pressure Monitoring System (TPMS)
The new Accord uses an indirect Tire Pressure Monitoring System (TPMS) that uses the existing ABS wheel-speed sensors to continually monitor the rotational speed of each wheel. Because a tire with low pressure rotates more quickly than one with a higher pressure, by comparing these values with a specifically designed computer algorithm, indirect TPMS can determine when a tire is low on pressure. This information is delivered to the driver in the form of a warning symbol on the instrument panel. Special logic included in the TPMS processor is designed to eliminate false warnings."
 
I disabled that crap and check tires visually.
 
When I installed my aftermarket 19's, I put the valve stem sensors on that report to a small square screen powered in the 12v plug inside the car. Its meant for cars without TPMS, but I don't much trust this system to save my rims. Now I can see real-time individual numbers.
 
Measuring wheel speed to determine tire pressure.... sounds reliable to me :|

What’s next, measuring fuel level by vehicle weight?
If it means saving a few bucks, then YES.

Honestly, an indirect system is cheaper for the consumer too in the long run. But from an everyday convenience perspective, a direct system that can display each tire's individual pressure is so nice.

It's perfectly reliable. Just not convenient for the end user.
 
The cost is why Honda has the indirect tire pressure system. It would be nice if Honda gave you choice or offered a per tire pressure system as an option.

Here is what I am using, had a similar system on my previous car without TPMS, and it worked reliably for 3 years. Once in that stretch I took them apart with the tool included and changed the batteries.

I will venture to say that the majority of people are riding around with the TPMS light on, especially when the weather gets colder .
