What Does It Mean to Be Tyre Sensor Safe (TPMS)?

July 20th, 2020

If you look at a bottle of Slime tyre sealant, it clearly states that the product is tyre sensor safe. But what exactly does that mean?

In 2007, the National Transport and Safety Authority (NTSA) ruled that all new cars were required to have tire pressure monitoring systems (TPMS). These sensors attach to your valve stem on the inside of the tyre, collect your tyre pressure and then transmit that data to your car’s computer. When the air in your tyre drops to an unsafe level (below 25% of your recommended tire pressure), then a warning light goes off on your dashboard.

Tyre pressure monitoring systems have greatly reduced tyre blowouts and increased overall driver safety. By receiving a warning that your tyre is low, drivers have the chance to air up or repair a tyre if needed.

So why does it matter if your tyre sealant is tyre pressure monitoring system safe? To inject into your valve stem, tyre sealants have to be able to pass through the tiny hole in the tyre pressure monitoring system easily. In a sealant that uses physical fibers to block up a puncture, this means that the particles must be specially designed to be small enough to pass through the sensor, but large enough to still reliably and efficiently plug holes.

We call this unique Slime formula Fiber-Seal Technology. It ensures that we fix your flat tyre puncture, but don’t harm your tyre in any way. If you take your tyre to a mechanic and he says the sealant has broken your TMPS sensors, he is incorrect! The mechanic simply needs to rinse out the sensor with soap and water (Slime's environmentally-safe formula cleans up easily with water) to remove any lingering sealant and your tyre sensors will begin functioning normally.

Next time you pick up a bottle of Slime tyre sealant, look for the TMPS symbol and rest assured that your tires are in good hands.
