Any tire loses air slowly at the rate of 1-3 psi a month due to osmosis. However, a stronger leak may be the result of the following issues:
- Wheel elements damage
- Tire damage
- Temperature change.
What is a Slow Leak?
Slow tire leaks are exactly what they sound like: small vulnerabilities in a tire that cause it to lose air gradually over a long period of time. Slow leaks differ from typical tire leaks because you may not be able to spot them unless you know what you're looking for.
If a tire has deflated more than 25% from the recommended pressure, it can be hazardous. Like any other kind of leak, slow leaks eventually decrease the tire's air pressure to dangerously low levels. If this decrease in tire pressure occurs while you are driving, the tires will generate more heat than normal. This excess heat and friction can wear through the rubber unexpectedly, causing a blowout. This risk is particularly common while driving at freeway speeds.
How to identify a slow leak?
If you suspect that one tire has a slow leak, you can perform a basic check in your own driveway or garage. Simply use water to test for escaping air. Perform this test after your car has been at rest for at least 30 minutes. Then, use a hose or a container of water to wet down the tire. Observe the surface of the tire closely. If there is a leak, you should notice bubbles that break through the water where the air is escaping.
A More Efficient Way to Detect A Slow Leak
However, not all slow leaks are detectable in this way. If you have a TPMS system in your car, it won’t be able to tell you if you have a slow leak at the early stage. When it does alert you, it’s already too late.
To identify a slow leak as early as possible, I recommend the Slow Leak Detection feature in the ZUS Smart Assistant App, enabled by the ZUS Smart Tire Safety Monitor. With the Accutemp Algorithm, ZUS is able to alert users for a Slow Leak that other similar systems aren’t capable of.
When you receive the Slow Leak notification on your ZUS app, the first thing you should do is to find the nearest tire shop and get the issue fixed.
What Everyone Else is Saying about ZUS Smart Tire Safety Monitor?
"Its solution is the Zus Smart Tire Safety Monitor: a set of four Bluetooth-connected pressure and temperature sensors that attach to each tire, along with an app that tracks tire temperature and pressure history. It then uses an algorithm to normalize the temperature fluctuations, so that it can get a clearer read on potential leaks, even those of a negligible nature..."
