Alternative set of wheels w/o TPMS

[ℬête Noire]

Has anyone here run, or heard of someone running the Model 3 w/o TPMS installed? How intrusive is the nag, can it be cleared or will it always be there until you swap back? Does it get in the way of other [unexpected] error messages (that I’m likely to care about)?

One could put TPMS sensors inside a pressurized sealed container to avoid the nags. However, in my opinion modern tires are so advanced that cars need TPMS. A driver is unlikely to notice a slow leak until the tire disintegrates and causes major damage to your vehicle or possible loss of control by an inattentive driver.

That'd wouldn't work for my goal here, to save $200 on TPMS.

I should have include background. These wheels are not for regular daily road use, rather off-street use. Tire pressure will be checked manually regularly anyway. I've noticed that the Model 3 isn't that good about picking up pressure when the vehicle is parked. Normally I have to drive some to get a new reading to register.

Not sure if that's due to Tesla's choice on TPMS, if the Model 3's antenna design has a hard time picking up the signal, or there is some other reason like a very low scanning rate?

P.S. It's the kind of behavior I'd expect from indirect tire pressure monitoring, that uses wheel rotation speed. However I didn't think those were precise enough for 1 PSI granularity is pressure measurements?

I think to save battery power the sensors only send a signal when they sense movement.

I take a different approach to track driving. I installed an aftermarket TPMS system in my (much less expensive than a Tesla) race car to help me know what is going on with the only part of the car that touches the road. Unfortunately I can only use it in one of the two classes I compete in.

I've seen different behavior in my other cars.

In autocross you don't really even have time to glance at your speedo much less any other gauge. ((Well I sure don't, I'm happy just to be able to keep up with seeing the next couple of cones so I don't run over them ). I suppose these tires would be plausible for a circuit track but they're 245/40 on 18" rims so if I ever took that step (other than an occasional leisurely lap day for grins?) I expect I'd get something else as those are about 2.5% shorter than stock. Shorter tires means the car's torque decline starts at lower mph meaning you'll lose acceleration ability. If you're going to be doing 70+mph you want taller tires since the direct drive drivetrain means they are the only "gear shifting" you have.
