I am ditching the run flats and installing Michelin Super Sports. Any suggestions on what to do about the tpms module inside each existing tire? Do I need to buy new modules?? The vehicle is a 2013 with 28K miles on it.

Hopefully I can still use the existing TPMS modules and the tire installer will put new gaskets on each module before mounting the tires.

Suggestions are greatly appreciated.

Generally the installer does this without issues. Best of luck.

Going to reset itself a few mins after leaving the tire shop, just make sure you tell installer what pressure you want if different than standered as the reset will be for the tire pressure you have when it resets. Make them check the pressure twice if not a realy good shop some guys get lazy. No biggie though you can reset again when you get home if pressures are not what you are looking for.
If you did not think of it may want to save a tire for a cheep rim to be used as a spare.

You don't need new pressure sensors, when your tires are replaced the shop won't need to mess with them.

The sensors have batteries in them that are supposed to last 7-10 years or so. I just got new tires in my 2008, and the sensors worked fine, but I replaced them because 1) the batteries will likely die soon, and I'd have to pay to unmount and remount and balance the tire(s) to replace them, and 2) I had a lot of corrosion in the valve stems, and just replacing the valve stems (which are matched to the sensors) didn't make sense.

The tire installer will know what to do.

But in general, if you are getting new tires anyway and the car is 7+ years old, I would replace them. Also check for corrosion in the valve stems. My corrosion was so bad I couldn't put any air in the tire, the side of the valve stem broke off when I was trying, and the tire shop had to grind off the old sensors.

And when you get new ones, don't get BMW OEM ones, they are expensive. I paid $1xx for a set of four Huf brand, pre programmed.

THANK YOU for this valuable info

FYI, the TPMS sensor is more part of the wheel than the tire. Here's a picture of a similar unit (not a BMW, I know, but the concept is the same). Tire installer really won't touch it.

I have had a shop damage one while mounting a tire, though. Luckily they were reputable and replaced it that day at their cost.

The cheapest ones I have found are these:

About $140 for the entire car. Not terrible.

Very useful info. Thanks!

I agree with jwalker87. Even if you get new set of wheels, you can transfer your stock tpms to your new rims.

Good choice of replacement tires. I just replaced my Michelin PSSs with a new second set just last week. Couldn't be happier.

As far as TPMS, everyone pretty much summed it up.

I think those were the ones I got. They are universal (to many car models), and must be programmed for your car model. I got mine off ebay from a guy who preprograms them, so I ended up paying about a $10 premium. I know that most tire shops most likely have the equipment to program Huf brand sensors, but I liked the idea of taking them in ready to go so I didn't have to worry about the shop having to program them correctly.

Also, our cars will automatically relearn the new sensors when you reset the TPMS system via iDrive/BC. Some cars require a bit more effort to learn new sensors.

A side note, with my factory rims, the valve stem is a bit short, so I went to AutoZone and got a valve stem extender for a couple bucks. I leave it in the glove box so it's handy when I need to top off the tires.

As said by others, TPMS batteries tend to last 7-10 years. Since yours are only 3 years old, you should be fine through this next set of tires. This decision will be harder when you buy tires 3 years from now.

It is common to replace the gasket or tire stem (depending on model of stem and TPMS sensor) to make sure you don't get an air leak. If your installer offers a TPMS rebuild for 5-10 per sensor, this is usually just the seals and stems. On 3 year old rims, your seals and stems are probably in good shape as well.

Buy a TPMS Emulation Module. It's $250, and you will save money in the long run since TPMS have to be replace every so often. This makes swapping wheels easy.
