I have a 99 corvette , bought brand new wheels, tires, sensors , I can't fit a donut magnet I tried different magnets and it doesn't want to honk , help!!! I don't want to scratch these rims either 😫
They do make them with a rubber donut around the magnet also. I have one. Think I found it on the auction site.
Forgot to ask, do you have the factory sensors that GM used or aftermarket ones? I have aftermarket ones and I had to use an electronic relearn tool. They didn't like the magnet.

I was able to train mine with a magnetic stud finder. I'm sure the circular magnets designed for the task would work better- but I used what I had and it worked.
Some after market sensors do not learn from the magnet method. You need to get the dic ready then go to the first tire and let air out fir a few secs until you hear the horn, then move into next wheel until all four are done
A "snap -in" TPMS sensor has a rubber stem like that. But - snap-in sensors should not be used on a Corvette wheel because they not rated for high speeds. I have not seen OEM C5 sensors, but i bet they are the metal valve stem type as others are suggesting.
I used a magnetic parts tray from Harbor Freight. I was looking around the shop and that's the first magnet I saw. Worked like a charm. My sensors are new from America's Tire. I had them installed with my new tires.
Thank yu guys ! They are aftermarket ones , I honestly going to go check if they are in fact sensors in there cause they ain't cheap , would I have to place the magnet thru the inside wall of the rim or can I go thru the sidewall of tire ?
So I know it's too late now, but the best thing to do is to program the sensors before they're installed, and then label them for the shop so they get put in the correct position. I bought a magnet for this purpose that you slip over the valve stem. It was round, and covered with rubber so that it doesn't scratch the rim. I can see from your picture that you likely don't have room to do that. You'll never reach it through the inside wall of the rim. It needs to go around the valve stem. I hope you can find a strong enough magnet that you can fit in the space that you have. Good luck.
The easy option is to find a tire dealer that has an electronic TPMS tool. That tool can trigger the TPMS sensors during the relearn procedure and will get the sensors properly registered for the car. You just put the car in relearn mode and trigger the sensors in the right order going around the car. You put the tool next to the tire near the sensor with the tool in Trigger mode. The horn honks once at each wheel and twice when you get the last wheel. Takes maybe 2 minutes to do the car. A decent tire shop should have the tool and should do this for cheap or even free.

I would go back to the tire store and have them break down one if the tires and find out if there are even sensors in there

When I had my last set of new tires installed on my CCW wheels, per my request I had the shop install new sensors as proactive maintenance. The shop installed aftermarket sensors and they would not program. I then purchased a set of new OEM GM AC Delco sensors and had the shop swap out the aftermarket sensors. The OEM sensors fired right up and were programmed on the spot.
Go back to the tire shop and have them do it. Should be included in the price. 97-2000 sensors are different than 01 and above. They don’t look like the 01 sensors so you should be fine. But the tire company should make them work
