Flattened tires x 11
I am the victim of someone continually flattening my tires...

I am the victim of someone continually flattening my tires--they are letting the air out, not slashing. Is there a motion dector that I can put on my car that can send me a signal inside so I can go out side and catch them??

Hook up an electric fencer to the car body. They will lose all interest in letting the air out of your tires and will probably make enough noise for you to catch them.




I like the electric fence idea. An apprentice I worked with did that, had the unit in the trunk with the hot wire dangling on the ground. Sure stopped us messing with his car. We worked on the railways, he also had the air horn off a loco to blast an unsuspecting car driver as they drove over the rail crossing. Those were the days, when you could pull a stunt like that and it was taken with humor.

I had a problem with someone stealing my tools. I took a 555 a power transistor and a spare ignition coil and set it up so the thief was extremely happy to leave my car alone, once he
got loose. It did just about do in the neighbor's dog when he lifted his leg on the wheel, but it wouldn't actually do any permanent physical damage. It had powerful influence on
the criminal psyche.


In many states what you did is illegal. IIRC, it is actually a felony in a couple.

Thieves tend to shy away from reporting you to the police. And they would have no better case than with the electric fence. After all, it did work to repel the neighbors dog.

Afterwards how did you get access to your own car?

I just unplugged the trailer light connector that
supplied the power and unclipped the ground rod.
You wouldn't want to forget it was there.

Talk to an alarm and security company. They can sell you a motion activated infrared security camera and recorder which you mount on your house and point at your driveway. Ask them for a demonstration so you can see if the picture would be good enough for a person to be identifiable. You then have a recording of whatever happened. Motion sensors can also turn on a spot light if you just want a deterrent.

There are all kinds of security systems that incorporate motion detection.

I have to point out that it may not be real safe to confront this criminal directly.

Are you sure it is somebody?

When we were having tyres let down I went out one day and found a cockatoo with it's beak on a valve enjoying the breeze.


Fix a "Pressure Sense Tire Inflator" PSTI Patented by Nanda, which senses the pressure drop inside the tire and automatically balances the pressure to preset value... Be sure to fit the inflator at proper location and balance your tires with PSTI... Hilarious... need some of these once in a while...

I suspect that there's an attempt to convey a message, not necessarily a criminal message, here.

The tires aren't being slashed, they're being flattened. That's more work than just driving an ice pick through the sidewall.


Are you parking in someone else's long time spot?


It sounds as if you are the victim of a prankster rather than a criminal.

Slashing the tire would be a criminal offense since property damage has occured. Since no property damage is occuring, it is not a crime.
For instance, using an electric fence voltage source to electrify the body of the vehicle could result in a lawsuit.

Even when property damage is occuring. The installation of "booby traps" to catch/embarrass/harm the perpertrator is usually against the law.

Any attempt to harm/confront the party that is removing the air from your tires could be a criminal offense depending upon the results of the confrontation.

Perhaps you should reflect and determine if you have upset someone or just have a friend with a very warped humor. Capturing the perpertrator on film and contacting the authorities is your only option. Although the results might be less than you expected.

Sell the car to that hooligan.
Buy a bicycle from him.
He will ride the car, get fat, and eventually die.
You will ride a bike, become healthy, and stop worrying about the car.
Keep the bike in your house. This prevents the hooligan from accessing it freely.

You can write Thank You, either on the tire or put on the splash board "Thank You".

I can assure you it would stop within 3 days. This type of incident happend with me, "Thank you" did work for me.

Best luck,

Sucessfully, but this was 4 years back

I'm sorry - this thread is too funny.

Start catching a lift in to work with someone else. Alternatively, you can flatten several of top Management's tyres. In the ensuing chaos, slyly mention that yours were also left deflated, absolving you of guilt. It'll soon stop after the manhunt begins... Unless of course it's the MD who is deflating your tyres, in which case I'd advise you to find a new job...


You should google X10 who have low lux cameras to image the suspect and do a tape of the crime. Then procede from there.


Since this is apparently a practical joke or simple harassment and the tires aren't actually being damaged, then the solution is simple: tamper resistant valve stem caps.
