Thought I'd write this up because I saw some of this information during a search, but not everything in one place.
I have a 2017 SV which has 215/50/17 tires on it. I'm setting up a winter wheel set and got some never-used Nissan OEM Steelies on Craigslist. They are 16x6.5 wheels and I'm going to put some 205/55/16 winter tires on them. The question was ... what to do about the TPMS? That usually means registering the wheels to the car every time I swapped wheels, which would be a pain because it would involve a drive to a dealer or tire store. I'd prefer to just swap wheels myself each Winter/Summer season since it's at most a 15 minute job.
After some research, I found the Autel MaxiTPMS system and thought I'd give it a go. You need the 315MHz sensorshttps://www.amazon.com/Autel-MaxiTPMS-Programming-Accessory-MAXITPMS/dp/B019I2CMF6/ref=sr_1_10?ie=UTF8&qid=1507581803&sr=8-10&keywords=autel%2Bmaxitpms&th=1
With this system, you can clone the OEM sensors to some new ones so that the car never knows that you switched wheels. You have to buy a sensor programmer and four new TPMS MX-Sensor stems. Grand total on amazon was about $230 ... way cheaper than buying new sensors from the dealer at $100 a piece! The process is pretty simple, just copy each individual TPMS of the stock wheels and program the codes to the new Autel MX-Sensors. Here's some pics of the process:
1. First gotcha is to install the software and MaxiTPMS PAD on your Windows laptop. You probably have to go into setup and do an upgrade of the software and PAD after installing to get the latest firmware for the PAD.
2. Then head out to your LEAF and bring your gear. Turn on the car so that it activates the TPMS in the wheels. You can make sure it's all working by placing one of the MX-Sensors on the scanner PAD and hitting TEST
3. Next, go into Copy Sensor tab in the software and hold the PAD up to your wheel. It should only take a few seconds to read the code off of the original TPMS. Click Test and it should read the code off of the OEM.
4. After you have copied the code off of the OEM wheel, place one of your MX-Sensors on the PAD and hit "Program". This will clone the code onto the new sensor. I wrote the wheel location and code on each box so I would know where to install the wheels when I did the Winter swap. You probably don't have to do this, but this way the car will not have to relearn the position of each wheel.
5. That's it! Repeat the process three more times and you're done. You now have two sets of wheels that you can swap back and forth without having to reprogram the TPMS each time.
One thing to note is that when I ordered my parts, one of the MX-Sensors was bad so I had to send it back to Amazon for a replacement. I don't know how well these are inspected before shipping from China so if you're on a time crunch, order a couple of extra sensors in case you get a bad one, too.
If you already have your tires mounted... Check out this guy on YouTube for a video walk through of installing the TPMS on existing wheels.https://youtu.be/Maunq29ow2U
