Is it possible to run TPMS in track wheels?

I'm still waiting for my track wheels to arrive, so I'm running the OE 20" wheels with Cup2 tires.
I liked being able to get an indication of pressures on the fly.

Question is...
When swapping out to track wheels, will the car learn (find) the new TPMS?
& how long would it take for the car to adapt & start displaying data.

This isn't a huge deal, as I always check hot temps & pressures in the pit lane.
It would however be nice additional data mid session.

Yes it is. I have TPMS in my track wheels.

After changing the wheels you will need to tell the car you changed them by going into the TPMS settings and selecting the new wheels size (even if it hasn't changed - you still need to select it.)

I'm looking through various supplier sites for a set of TPMS to install in track wheels.
It's mind boggling to say the least.

I haven't found any sites that list TPMS for the 718 specifically.

Are there aftermarket compatible sensors or is the dealer the only source?

i never rely on tpms for track wheels, it's a waste of money imho. you should be manually checking your tire pressure and wear after each session and the tpms readings cannot be 100% relied upon. it's good enough for street use but i would not suggest anyone rely on them when you are driving on a track.

Sorry to bring back an old thread, but having the tpms in your track wheels help more than you think. I monitor the pressures and see when my tires are up to optimum temp by when pressures have reach the usual hot pressures. Also helps by showing you if you are over driving the tires, by pressures being over your intended hot pressures. Helped me alot during time attack events and on normal open lapping days as well.

Interesting factoid: I finally got a chance to watch last year's Petit Le Mans this past weekend, and at one point one of the cars came into the pits after blowing a tire. The tire carcass managed to wrap itself around the suspension, exposing the interior of the wheel. Lo and behold, there was clearly a TPMS sensor mounted on the wheel. Surprised the heck outta me, but maybe the systems are getting good enough that they're able to provide useful information to the drivers.

I opted to go without TPMS sensors on my track wheels, but I may install some just to try it.

I’ll never go without them. Last time I was at the track I was about to go out for a last run and picked up a nail 10 ft before entering pit lane. Warning light went off, and I was able to get out before entering the track. If I would have gone out, it would have been a disaster. Worth the $250 to put them in, for sure.

Where did you get some for $250? Suncoast has them for 125 each plus 25$ for a stem

also, do they need to be programmed or will they auto pick up whenyou reset the system by changing the size?

Tire Rack sells compatible ones for less. I know they'll program them for you when you buy a set of wheels and tires; I assume they'd program them to work with your car if you buy them without wheels or tires, too.

The Cayman will recognize that you have different sensors installed after a little driving and ask you to confirm what kind of wheels and tires are installed (wheel size, winter/summer).

There are a couple of compatible brands but only go with Huf brand they are the OE supplier and have metal stems. (& carried by Tire Rack)
I learned the hard way when the other brand failed on track.
Fortunately tires held enough pressure to get back to the pits.
