MultiSeal ( Flat-Out ) and TPMS

I'm gonna say you don't want to be a Guinea pig. And no need for that stuff in highway tires anyway.

Tire experts will tell you to never put that kind of junk in a tire - and it will ruin your TPMS sensors.

I don't know about it ruining the TPMS sensors that are attached to the valve stem, but it could certainly get into the valve stem itself and cause issues.

Just like Nancy always said: "Just Say NO" to Multi-Seal.

External TPMS sensors depress the valve in the stem so that they can sense pressures - creating a direct path to the sensor from inside the tire.

The guys at the tire store will hate you.

If these products work as advertised, I probably would not be seeing those guys at the tire store. I am surprised that I have not received any responses from users of these products. I am hoping for more than opinions or anecdotes...... I'm hoping to hear from those with actual experience..... anyone out there?

I have used a similar product in my mower tires. Obviously, I don't have TPMS on my mower, but it gummed up one of the valve stems so badly that I had to replace the valve stem completely as you couldn't get air in or out even with the valve core removed.

And yes, it's a nasty mess when it comes time to replace the tire.

Thank you! This is the thpe of personal experience comment I was seeking.

Tires will eventually need to be replaced, and the tire tech will hate you. Most people here don't like this stuff, which may explain the lack of response from actual users.

My experience: This does not directly address your question because a TPMS was not involved.

I own a 6' utility trailer. About 20 years ago my brother asked if he could borrow it. I said sure, and he came and got it.

Fast forward about 10 years. A tire on my utility trailer went flat. I got out my air compressor, but it would NOT air up. I took the wheel off the trailer and took it to a tire shop. They removed the tire, then came and asked me if I had ever put Fix-a-Flat in it. I said that I hadn't, but the trailer had a previous owner, so I didn't know. They said SOMEBODY had put Fix-a-Flat in it, and it had rusted out the rim. I needed a new rim. They said that if I ever put that stuff in a tire, take it to a tire shop as soon as possible because they have to rinse all of it out before that can happen.

When I got back home, I called my brother and asked if he had put Fix-a-Flat in my trailer tire while he had it. He said yes, the tire went flat and he did.

(That particular brother could break an anvil. I loaned my Father my chain saw one time. While he had it, my brother borrowed it from him. When Dad returned the chain saw, it was a brand new one still in the box. My brother had managed to destroy the chain saw, and Dad felt responsible since he had loaned it to him.)
