Largest Functional Tire Without Mods

Just a question, do you get High Pressure warnings that will not stop? Mine warns me every 5 minutes or so and drives me nuts, it is as if the programer never envisioned this vehicle being driven on an interstate in Texas in the summer.

I have my tyres set on 36 cold and they get up to 44 after long highway runs in summer.
I set the tyre pressure sensor at 40 PSI and no problems

I find if the tire temperature gets too hot, it will not reset the pressure. it only works on "cold" tires. Maybe under 100 deg F?

I’ve not had a problem resetting on the fly but an alternative, if you are running 36-38, is to pressurize to around 40/42 psi when cold set the level then deflate back to “normal”.

Yes, exactly what I did.
It works a treat.
Only time I struck a problem when was ambient temperature hit 44 degrees Celsius (111 Fahrenheit ) and I was 3 hour drive on the motorway.
I had to reset the tyre pressure on the fly.
