Most every bike tire lists its recommended pressure right on the edge of the tire’s sidewall. It’s usually a range, say from 35 to 80 psi (that stands for “pounds per square inch”). The only way to know how much pressure you have is by using a pressure gauge — squeezing your tire isn’t accurate enough.
How do I know what PSI my bike tires should be?
Once you know the psi range, use your tire gauge by placing it on the valve and pressing down, causing the needle on the gauge to move and display the pressure. Alternate between the air pump and gauge until you reach desired pressure. To make things easier, get a pump with a built in gauge.
How do I know if my bike tires are over inflated?
As a rule of thumb, when you sit on your bike and clip in, you should visibly see a slight bulge in the tires. If not, drop the pressure 5 psi per tire and try again.
How do I know if my tires have enough air?
Check to see when you have enough air pressure in the tires by releasing the inflation lever. The gauge on the hose fitting will show if you have approximately enough air pressure. You can check it again later with your own gauge. At this point, it is better to slightly overinflate the tire.
What happens if you put too much air in your bike tires?

Is it normal for bicycle tires to lose air?
Regularly pump up your tires. A perfectly functioning tire will loose air over time. For starters, you should know that a normal, brand-new tire and tube will loose air over time. … As a guideline, a typical skinny road bike tire (700x23c) can lose half of its pressure in two days.
What the lowest tire pressure you can drive on?
If you have standard passenger tires (ninety percent of vehicles do) the lowest tire pressure you can generally drive with is 20 pounds per square inch (PSI). Anything under 20 PSI is considered a flat tire, and puts you at risk for a potentially devastating blowout.
How do you tell if tire is flat or just needs air?

How do I check my tire pressure without a gauge?
You can test air pressure by pushing hard at the tire and seeing how it feels against your hand. If it doesn’t have any give but instead feels hard as a rock, you should have enough air. If the tire sinks a bit when you push the tire, your tire is low on pressure.
Is 35 psi too high?
Higher pressure generally is not dangerous, as long as you stay well below the “maximum inflation pressure.” That number is listed on each sidewall, and is much higher than your “recommended tire pressure” of 33 psi, Gary. So, in your case, I’d recommend that you put 35 or 36 psi in the tires and just leave it there.
What happens if tire pressure is too high?
If tire pressure is too high, then less of the tire touches the ground. As a consequence, your car will bounce around on the road. … As a result, not only will your tires wear prematurely, but they also could overheat. Overheating can lead to tread separation — and a nasty accident.
