Are there other explanations for slow tyre pressure loss?

Asked by: Latoya Epstein

What causes a tire to lose pressure slowly?

Hitting a pothole or damaged curb will “flex” tire sidewalls, forcing them to lose a little air each time. Refilling the tire with air is usually all that’s necessary, but you should also check for any signs of tire damage after hitting a pot hole, including sidewall bulging, slashes, or poor sealing.

Can a tyre lose pressure without a puncture?

One of the most common reasons for tyre pressure loss, and the main reason for a tyre losing pressure when there’s no leak, is changes in the temperature of the outside air. Temperature changes affect tyre pressure because of air’s nature – contracting when it’s cooled and expanding when heated.

Why is my tire losing air but no hole?

Flat tires aren’t always caused by a hole in the rubber. Instead, a malfunction or leak in the valve stem can be the culprit. The valve stem is the part of the tire that you unscrew when adding air. Any damage or even dirt on this small piece could cause your tire to lose air until it’s completely flat.

How long does it take for a slow leak to flatten a tire?

It can take as little as two minutes or up to 60 minutes to fix a tire leak. Some leaks are more complex than others. A small nail hole could take just a few minutes to repair—hopefully, your ice cream won’t melt while you fix the leak! A nail hole (as long as it didn’t enter the sidewall) is pretty simple to fix.

How do you find a slow tire leak?

Quote from video: The soap is causing bubbles. Obviously when the air is gain touched to it. So that's how you easily find a leak in 3.5 seconds.

Why does my brand new tire keep losing air?

Improper Seal – New tires can go flat if they don’t seal properly. A simple mistake such as not cleaning the seal properly or failing to remove a label can lead to an improper seal. Tires may not get a proper seal when there’s a problem with the rim.

How much tire pressure loss is normal?

The typical rate at which a tire will lose pressure is about 1-3 psi per month. If you don’t inflate your tires for six months, then you could lose as much as 6-18 psi. This will likely give you low tire pressure since the normal psi range is about 30 to 35.

How can you tell if you have a slow puncture?

Pulling- If you’re driving on a flat road and relax your grip on the steering wheel and notice the vehicle pulling to the left or the right, it’s a sign that the pressure is low in at least one of your tyres. If your tyre pressure remains low, it is likely that you are suffering from a slow puncture.

Why does my tire keep going flat in cold weather?

The main reason for this is the dropping temperatures, which cause the air to become denser and consequently lower the tire pressure. Couple that with tires naturally losing pressure over time, and fall and winter can be a busy time for pressure checks and adding a little air.

Can a slow leak in a tire be fixed?

The leak should then be permanently fixed using a proper tire repair consisting of a cured rubber stem and repair unit. If the leak is caused by a damaged valve, a trained tire technician can typically replace the valve at a minimal cost. In some cases, however, the tire may need replaced.

How do I know if my tyre valves are leaking?

To check for a leaking valve, simply remove the cap and put a little saliva on the valve. If it bubbles, you have a leak. If there are no bubbles, the valve should be fine. If the valve is fine, this may mean you have a small leak or a slow leak from a non obvious puncture.

Can you drive with a slow puncture?

Driving on a slow puncture for any longer than necessary is dangerous because that slow puncture is more likely to become a fully flat tyre the longer you keep using it. The usual culprit of a slow puncture will be debris that has pierced the rubber.

Can you drive on a tire with a slow leak?

Driving with a slow leak in your tire is potentially dangerous because it can cause a flat tire. Once the tire becomes flat, it can become a blowout hazard. A blowout can cause you to lose control of the vehicle, putting yourself and others at risk for a car accident.

How do I know if my tyre valves are leaking?

To check for a leaking valve, simply remove the cap and put a little saliva on the valve. If it bubbles, you have a leak. If there are no bubbles, the valve should be fine. If the valve is fine, this may mean you have a small leak or a slow leak from a non obvious puncture.

How do I know if my valve stem is leaking?

Diagnose and fix a leaky valve stem



Squirt soapy water into the tire valve stem. If you see bubbles form, you have a slow leak.

Why does my brand new tire keep losing air?

Improper Seal – New tires can go flat if they don’t seal properly. A simple mistake such as not cleaning the seal properly or failing to remove a label can lead to an improper seal. Tires may not get a proper seal when there’s a problem with the rim.

Can valve seals cause low compression?

Exhaust valves and air intake valves at the top of the cylinder can also get overheated, and leak gas or the valve seals can become too worn to seal the gas in properly. Either way, the result is often low compression.
