Wheel speed TPMS superiority

[GenSan]

2024 Toyota Rav4 Prime XSE TPMS is DIY friendly when swapping seasonal tires. Reset and relearning is accessible from dash menu. Just drive around and system reprograms each wheel. No more dealer/tire shop required reprogramming.

Interesting. My 2005 Odyssey actually shows individual pressures in the tires.

My 2022 Accord has the newer setup, I'm sure. It sounds to me like it is a better way to go-- no TPMS batteries to die every decade or so. No need to add them to replacement wheels. No need to re-pair TPMS with the car when you swap winter to summer tires.

So what do you do when all 4 tires deflate uniformly from neglect? No one tire rotates at significantly different rate. ABS tire pressure warning systems fail in this scenario.

What do you do if you replace one tire 10,000 miles before the others?

There are "self winding" TMPS sensors available. Manufactures chose not to use them. Replace your sensors every 7-10 years with new tires and you'll be OK.

I'm at a loss as to why people act like tire pressure gauges don't exist. I'm partial to the newer Honda setup. I keep gauges in the driver's door pockets of all my cars, so I always have a gauge available.

Yeah, I don't understand this wireless telephone stuff in the house nor cellphones. We have perfectly good wired telephones!

As has been stated many times here, TPMS gives warning when a tire is deflating. That often starts after one gets in the car and finishes before one gets out. I have screw-on valve stem TPMS on my motorcycle which has saved my ass 5 times in the past 85,000 miles. If you don't know, it is very bad news to find out after the fact that one's tire is flat when riding. Every time pressures were good when I left home. One of the latest events was at the end of a 250 mile day. 30 miles from home noticed rear was suspiciously low (42 v 45 PSI). Watched it slowly leak until 35 PSI when I arrived home.

Recently my sister got a low pressure warning just a mile from her hotel on a 400 mile day. Whatever punctured her tire had come out. She has a logging service and could see tire pressure started falling 45 minutes prior but her car doesn't have an easy PSI display and didn't alert until pressure fell to 75% of nominal.

I didn't even consider snow tires. That is probably the biggest benefit of the indirect TPMS.

You don't know you can get cloned sensors with exactly the same ESN as your OE sensors so when wheels are swapped your vehicle doesn't know the difference?

Autel and Schrader make cloneable sensors. One sensor model. Is programmed on installation to speak your vehicle's protocol and use any ESN one desires. The Autel sensors are 4 for $120 at Amazon. Requires an Autel TPMS scan tool to initialize.

According to wikipedia: Second generation iTPMS can also detect simultaneous under-inflation in up to all four tires using spectrum analysis of individual wheels, which can be realized in software using advanced signal processing techniques

Not really sure what that means though

It does do that. That was my point when I mentioned the system in my Tiguan as opposed to the older one on my Sienna.
