# Question: What Psi Should My Bike Tires Be?

## 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.

## Is 40 psi too high for tires?

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 is the air pressure for a 26 inch bike tire?

If you’re inflating 26inch tires (common on comfort and off-road bikes), you may find that the pressure range is wider, say “35 to 60 psi.” This is because these tires can be used on and off road. For the former, 60 psi is about right because it rolls optimally on pavement.

## What should I inflate my bike tires to?

Know the Tire Pressure You Need

Before you pump, check the sidewall of your tire: It should list the pounds-per-square-inch (psi) range that your tire can safely handle. Typically, a road tire can go between 80 and 130 psi, while a mountain tire holds between 25 and 50 psi. Hybrids usually take between 40 and 70 psi.

## What happens if you put too much air in your bike tires?

The higher pressure makes the bike feel fast but may actually be slowing you down! If the tire is too hard it will have a tendency to vibrate and bounce which increases rolling resistance and makes for an uncomfortable ride.

## How do you check psi without gauges?

Push your hand down onto the tire. If the tire feels soft and squishy, the tire pressure is low. If the tire feels rock hard, meaning you are unable to push down on the tire at all, then it is overinflated. If the tire feels too low, pump some air into it while keeping your hand on it.

## Is 50 psi too much for tires?

Every tire has a rated maximum inflation pressure. Often it will be found in small print around the rim edge of the sidewall. This means that the tire will safely carry up to 1477 lbs. and can be safely inflated up to 300 kPa (Kilopascal) or 50 psi (pounds per square inch).

Depending on the circumstances, repeatedly overinflated tires could wear out more quickly. It means center tread wear, an uncomfortable ride, and increased risk for a blowout. Note that a few PSI over your recommended tire pressure generally won’t put you in the danger zone.

## Is 30 psi enough for tires?

Being low on pressure doesn’t hurt the tire or the wheel at all, unless they get very low, like 10 PSI. Also, you should check your owner’s manual to see what the correct tire pressure setting is. 30 PSI is a safe bet, although the odds of your car specifying exactly 30 are rare.

## What PSI should a gravel bike be?

The idea is to strike a balance so the pressure supports your weight but doesn’t end up rock-hard. Therefore, more rider weight requires more tire pressure. For example, I weigh about 150 pounds and ride 30 PSI on my gravel bike. A rider who is 20 pounds heavier should definitely consider another 3-5 PSI of air.

## Can I put air in my bike tires at a gas station?

In most cases, no. The long answer: The reason you can sometimes use an automotive airpump on a bicycle tire/tube is because they share an identical valve. Therefore, it is much easier to over-inflate and even blow out your bicycle tire, if you were to use one.

## What is the air pressure for a 29 inch bike tire?

Tire Pressure

29er Tire Pressure with Tubes 26-30psi
29er Tire Pressure without Tubes 23-25psi
27.5 Tire Pressure with Tubes 26-30psi
27.5 Tire Pressure without Tubes 23-25psi
27.5 Plus Tire Pressure with Tubes 16-18psi

## How do you pump up a bike tire without losing air?

Try putting the head on less far, looking for where the valve only is opened when you use the thumb lock. Now pump. If no air goes in, open the lock and go a bit deeper and try again. Once you’ve pumped hard, open the thumb lock and you should get a short blast as the hose pressure blows out, but the tire should hold.

## Does bike tire pressure affect speed?

Summary: On really rough surfaces, higher pressures roll slower. Wider tires roll faster on rough surfaces because they can handle lower pressures. So now we know that higher pressures don’t make your bike faster – whether on ultra-smooth asphalt, on rough surfaces like cobblestones, or anywhere in between.

## Is 80 psi too high for tires?

The 80 psi is required if the tire is operating at rated load. You most likely have a load range E tire. I have run load range E tires for years on my 4 Runners at 32 psi front and 30 psi rear. This gives me real even tire wear.
