# Quick Answer: What is the best PSI for a road bike?

Contents

## What psi do pro cyclists use?

“It depends on the road surface, but 10 years ago the standard was 23mm tires at 8 or 8.5 bar, or 115, 120 psi,” Brown said. “And now it’s 25mm for regular road racing and 7 to 7.5 bar for front and rear, so a little less than 100 to 110 max on the bikes.” So what’s the deal?

## Is 60 psi too much for bike tires?

Imagine you’ve purchased a new set of mountain bike tires that recommend a range of at least 35 and no more than 60 psi. Begin by inflating your tires to the middle of the range, adjusting the inflation depending on your weight. If you’re a heavier rider, you may want to start off at around 50 psi for each tire.

## What PSI should my 26 inch bike be?

Recommendations. Mountain bike 26-inch tires are 2 to 3 inches wide, with knobby tread to give you more traction on challenging terrain and help channel mud and debris away from the bike. Inflate these to 30 to 50 psi.

## Is 40 psi too high for tires?

Normal tire pressure is usually between 32~40 psi(pounds per square inch) when they are cold. So make sure you check your tire pressure after a long stay and usually, you can do it in the early morning.

## What PSI should 28mm tyres be?

We’ve found in this example a 28mm tyre to be optimal, with pressures in the range of 79-84psi at the rear and 75-79psi at the front. ‘Also a 28mm tubeless tyre is the fastest setup [in rolling resistance tests]. At 40kmh a high-quality clincher tyre with a latex inner tube is about 2 watts slower.

## 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.

## What PSI should my tubeless tires be?

For a tubeless tire, you can begin with 26 & 22 psi respectively. Finally, for those with a Plus bike, you can even go lower with 22 & 18 psi respectively. Simply put, the softer you can run ’em, the better you’ll be.

## Why do bike tires deflate over time?

When not in use, tires get deflated over time. This is mainly due to the permeability of the tube and the small size of air molecules. Slowly air molecules find there way through the tube and valve seal. When it is hot the air pressure will be higher and the process goes somewhat quicker.

## Should I inflate bike tires to max PSI?

Road bike tires are always inflated to much higher pounds per square inch (PSI) levels than mountain bike tires. … The tires don’t sag down and create a large surface area, because it’s simply not needed. A typical road tire should be inflated to something between 90 and 120 PSI.

## Can bike tires explode?

Even with only a floor pump it’s possible to blow tires off – especially when a lot of roadies ran sky-high pressures such as 130psi or more. As road rubber and rims improved, blowouts became less common because the tires and rims didn’t fail.

## Is 24 tire pressure too low?

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.
