Pressure monitoring system

In order to keep tires pressure under control during a trackday or even during road driving, would a pressure monitoring system be any good?

I mean one of that systems with 4 sensors to be screwed on each wheel and a little display to be put on the dash and see pressure and temperature of each wheel.

Thanks for the attention :)

yes this could be an option. They are called TPMS Kit

They won't keep them 'under control', but good quality (usually expensive) ones will give you a better idea what the pressures are doing, so you can make any adjustments needed. Some will also monitor the air, and even carcass, temperatures.

Of course, they will also warn of a pressure drop, indicating a loss of air, hopefully before a bigger problem develops.

Some use a small dash gauge, but some can be integrated with some dash displays, which might be an option - something to check up on with both companies?

As an aside, you may like to have a look for NASCAR tire cheats - they have had some very ingenious cheats to manage the pressure build up during races - from very small holes drilled into the tyres, wheels, or even valve caps, to spring loaded valves, to illegal gas mixtures.

Thanks for the reply!

Given the fact that my car has a tpms system by factory (2018 gt86), is there a way it could be useful in some way?

Obviously, I would be interested in reading precise values of pressure and not looking at an annoying sign of 'low pressure' which is not as useful!

Hi Mattia!

Yes TPMS is an extremely useful tool in racing, you would not find many race car operating at a decent level without it these days. I did an Instagram post on this a while ago if you're interested in checking it out here. I also did a Youtube video a while back on tyre pressure in general you can find here.

If your car has factory TPMS then you may well be able to access this data via the CAN bus and log it externally. A lot of the hardware in OEM systems is quite similar to the motorsport systems, so getting good quality data may well still be possible!

Thank you very much for the high quality content linked in the previous post Tim!

My car should have a tpms direct system, I'll try to get to those data and find a way to log and read them!

My pleasure Mattia!

There are many different TPMS systems available these days. The system you go for depends a lot on your budget and the features you need. I saw Haltech released a very affordable one recently. I have not used it myself or gone through all the specs but probably worth checking out!

Also, if you haven't bought it already I recommend checking out our Data Analysis Fundamentals course. A lot of good info in there on choosing and setting up a data logger!

Thank you, I have seen the entire tpms from Haltech.

The pride is reasonable and the system seems to do it's job.

They produce 2 versions:

• external sensors fitted on the inflating tube (user replaceable battery)

• internal sensors fitted inside the wheel (battery not replaceable - lifespan of about 3 years and then you have to buy a set of 4 new sensors)

The external sensors version would be a little problematic when at the track and inflating/deflating the tyres different times during a session.

Regarding the Data analysis fundamental course, I'll buy as soon as i can, i love your contents! :)

Mattia, my preference would definitely be the internal system. I believe this would be the most practical, reliable, and safe.

The other considerations between the internal or external sensors is that a lot of race series and motorsport bodies explicitly prohibit the use of external sensors like these as they are at a higher risk of causing damage to the valve stem and thus a potential rapid tyre failure due to a loss of tyre pressure.

Thank you Tim and thank you Blackrex for the consideration about that rule, I didn't know it before!

I understood that internal is the way to go.

Now I just have to figure out how I could use my stock internal sensors... Or if it's just better to buy a new standalone system like the one from Haltech.

I will keep you updated if something happens!

If your car has stock sensors, this information may well be available over the CAN bus which you should be able to access through your data logger (if you already have one). Our sister company High Performance Academy just released a course on CAN systems that will be a great resource to you if it is possible to access the data of the factory sensors! You should check out the course here.

Yes, my car has stock internal tpms sensors.

The new can bus course is one of the few that I still have to purchase! Definitely on my list :D

Unfortunately still no data logger, I am starting now to "do" something to my car...
