TPMS for 2nd set of wheels / tires?

[Tifosi]

Short answer is yes. Each TPMS sensor have their own frequency and the ECU is coded to recognize only 4 at a time. There are devices that you can buy and do this on your own whenever you want ( https://www.ateq-tpms.com/en-us/products/quickset-x/). Again, the easiest way is to clone the original TPMS so the ECU will not have to relearn a different set of TPMS when you switch from one set to another.

There are numbers on the sensors and you can see them with the tires off. In this example it's 255E63C-- Toyota uses hexadecimal. Ask your tire shop before work starts. They might also have a machine that can generate a report faster than a tech manually scribbling this stuff down.

Although , not Toyota, I ordered a 2nd set of TPMS sensors off Amazon and took them in to the tire shop when I bought a set of winter tire on separate rims. They installed and programmed them with no extra charge. After that , I did the reprogramming manually every time I changed out the tires. You just have to be outside the range of the other set of tires, which for me was at the end of my driveway.

Hi

I have a 2021 Toyota RAV4.

I am getting a second set of steel wheels to mount snow tires for the winter.

Do I need to purchase TPMS? What happens if I don't? Will the dash light come on? Just curious what happens to a 2021 RAV4 with the absence of TPMS sensors?

Thanks

My experience on Acura and Honda: It may help you if you use the same tpms thru out the sets.
2008 Accord: 1st set of wheels are original with original tpms. 2nd set of wheels with 2015 Accord wheels + 2010 tpms sensors (from Craigs list). No lights or reset needed when swapping wheels.
2011 MDX: 1st set of wheels are original with original tpms. 2nd set of wheels with 10-15 Pilot wheels + used tpms factory oem 42753-STK-A04 (from Ebay). No lights or reset needed when swapping wheels.
2015 RDX: 1st set of wheels are original with original tpms. 2nd set of wheels with 2010 Accord wheels + used tpms factory oem 42753-TX4-A512 (from Ebay). No lights or reset needed when swapping wheels.

When I bought the Pilot wheels, it came with tpms Smart Sensor. The light came on because it was programmed for a different MDX year. I could've had it programmed for my 11 MDX but I bought a $22 oem set from Ebay instead. I changed the tmps at home myself using scissor jack.
