making the tire pressure system handle high pressure

[LowKeyMike]

I always give my dad what he wants bcs just want to keep him happy in his old days.
right now he wants a 2018 SV and to make it a tow rig. It's got these beefy Load Range E tires (rated at 125) that Imma help him pump up to 36 psi.
I'm guessing it originally had lighter duty tires bcs the sticker on the door says 36psi max.

Anyway, since he's towing for the first time, he aired these bad boys up to 70psi (the tire says 80 is the max).

Drove down the block, and the tire pressure light started blinking like crazy for a minute, then just stayed on.

Pretty sure it's freaking out because of the higher pressure.
So, the question is: How do you get the truck's tire pressure system programmed to be okay with this higher pressure?

Well, most vehicles nowadays are using pre-set pressure thresholds, and the 2018 Nissan frontier shouldn't be above 36psi. The system is probably abnormal because 70 psi is way above the recommendation. If it's just the light and nothing else seems to be the problem, then you can live it that way. You can't reprogram the tire pressure system, but you can find an aftermarket programmers or custom tuners that can do that for you.

I believe to get the light to turn off and function correctly, you'll probably need to bring the tire pressure down closer to the door sticker's recommendation when you're not towing.

yeah, that's not gonna cut it out. We know why the system is freaking out, so it's a matter of finding a way to go around it.

@LowKeyMike you have two options, either get a tool to reprogram the tpms, something like ATEQ Quickset, Autel TS508 or get emulators that will fool the system. Botth work well enough, so it's just a matter of getting the one that works the best for you

It's cool to help your dad with those big tires. If the pressure exceeds the factory specifications, the TPMS will go crazy. Holding down the TPMS button until it blinks will reset the system. After that, drive for 10 to 30 minutes at 25 mph. If the light remains on, either the sensors need to be checked or the pressure may still be off. Verifying that the setup is safe for towing is always a good idea
