Can I fill my tires with water so that I know where they're leaking from if they're punctured? Answered

No,what you need to do is jack up your car where the leaking tire is.Once you do that get you a spray bottle with water and soap.Just turn your tire slowly as you spray it with the water and soap,9 times out of 10 you can find the leak this way.It will bubble up the soap.Once you find the leak,just pull whatever it is out of your tire.You can get a Tire plugging kit for less than 10 dollars.Just make sure the leak is on the tread surface and not on the valve stem or leaking where the tire and rim seals.GOOD LUCK 2U

Just take an empty spray bottle and fill it with water, then add some dish soap. if you dont have a spray bottle a water bottle works too, just pour or spray the tire anywhere that you may suspect a leak. Make sure you check around the valve stem and bead! (where the tire meets the rim.) Anywhere a pinhole leak is will bubble like crazy! Good luck!!!

Nope...not a smart thing to do.
Water, being a liquid, has no compression like a gas so your ride would be prety rough.
You would probably pop your tyres hitting a pothole at speed.
Steering would be heavier and you would chew more juice lugging the extra weight around.
Tyres are heavy enough as is. Would be almost impossible to lift them if full of water as well.

It depends on what kind of vehicle the tires are on.

I suspect, tires that must move at high speeds (e.g. a car or motorcycle at highway speeds) should NOT be filled with water.

The reason why is because it will do strange things to the rotational intertia in the wheels,

https://en.wikipedia.org/wiki/Moment_of_inertia

if a significant fraction of the wheel's mass is made of water, and thus free to slosh and slide around.

The usual symptom of unbalanced wheels is vibration, that gets more intense as the car's speed increases. However that is for a fixed imbalance; i.e a wheel with too much unbalanced mass, but fixed in the frame of the tire. I do not know exactly what will happen for a fast moving tire filled with water.

It might be interesting to find out. I should search for stories of this, and see if anything turns up...

I have heard stories of tractor tires filled with water,

https://en.wikipedia.org/wiki/Tractor

for the purpose of making the tires heavier, but, you know, tractors do not move very fast.

By the way, there are other techniques for discovering air leaking from tires, well known to those who have studied the art.

If the leak is big enough, it will be audible, and the sound it makes is sort of a hissing sound. The amplitude of the sound tends to increase with the size of the hole.

This suggests that techniques for listening to faint sounds, like for example by using a stethoscope, might work for detecting those leaks too quiet to be noticed by just putting one's head near, or against, the wheel.

They make stethoscopes, intended for listening to machines, like cars, although I have never tried using one for listening for air leaks.

Another technique, a very common one, is to put a layer of soapy water on the tire's surface, and watch for small bubbles to appear at the site of the hole. This is a technique that works really well, but its only downside is that it is necessary to be able to touch, and see, every part of the tire's surface, for to search every part of the tire's surface.

If the wheel is still attached to the car, well, that makes it difficult to inspect every part of the tire's surface. For that reason, I think the usual method is to just jack up the car, and remove that wheel.

Then you can roll the wheel around, and see every surface of it. You can even dunk one side of it in a shallow pan, or tub, of water, for to search for evidence of bubbles.

Without the shallow tub, soapy water can applied in other ways, including: a spray bottle, or a rag, or a sponge, or brush. Really these are just the same tools used for cleaning things. I mean the kind of cleaning that uses soapy water.

An image search for "tire leak bubbles"

can show you pictures of what I'm trying to describe.

It is done the other way around, you take the inflated tyre and submerge it water to see where it bubbles.
Since most people won't have a strong enough press to get a tire under water the common solution is to just spray soapy water over the tire and then to check where it starts bubbling and foaming.
Funny thing is that suspicion is often confirmed by a loss of air inthe tires and if no punture it is often the valve - so take the cap off and test if it is leaking too ;)
