First of all if you have a flat tyre you might notice several things. The first thing you might notice is that your car does not drive or accelerate quite as quickly and after hills when you aren't applying the gas you may notice that it is quicker to decelerate and doesn't get carried quite as far simply by the momentum. This is of course a bad thing as it means you will get to your locations more slowly and because it means that you will find you will get through a lot more petrol a lot more quickly which is bad for the environment and is bad for your wallet. This is one reason that it's so important to identify a flat tyre quickly - another reason is that you will risk damaging the actual wheel so you might need these replaced too if you've had your tyre flat for a long time. Your wheel can even break under such circumstances and this can be highly dangerous.
Another symptom of a flat tyre is vibrating in the car. If you notice your car vibrates more than usual when driving then this can be a sign that a tyre is flat because your tyres actually provide an extra layer of suspension as well as your shocks (of course it is possible to misdiagnose a flat tyre as broken shocks). To tell which tyre it is which is flat you should try and locate the source of the vibration. If it's coming from the wheel then it's a front tyre, if it's through the back of your chair then it's more likely to be a back one.
The easier way to check which it is however is of course to just get out of your vehicle, to go around and to look at each of the wheels. Where the car is sunk and the tyre appears to be literally flat along the bottom this is where you have the problem.
Now you need to try topping it back up. Take it to a petrol station where they provide free air for your car and attach the nozzle to your wheel after unscrewing the cap. When you squeeze the trigger it will fill with air, and when you let it go the readout will tell you how pumped the tyre is in PSI (pressure). Once it's full (your manual will tell you how much to fill the tyres) you can replace the cap. Now be vigilant and make sure to keep an eye on your tyres. If it happens again soon after then this is a sign that your car tyre likely has a puncture and needs replacing.
