What size road bike tires should I use?

The CTC recommends the ideal relationship between a rim and tyre as being about 1.8 times. Rims measuring 15 to 17mm across are the most common used for road bikes and accommodate tyres ranging in width from 23 to 50mm.

Are 28mm tires faster than 25mm?

Yes, they are still aerodynamically superior, but the rolling speed advantages outweigh this, certainly at the speeds of regular cyclists and even up to the speeds reached by keen amateurs, even professional cyclists are now running 25mm tubulars and sometimes 28mm for the Spring classics.

Does tire size matter on a road bike?

Science has now proven that wider tires actually have less rolling resistance than skinnier tires. Wider road tires provide a more forgiving ride and improve handling through a, you guessed it, wider contact patch that makes endurance riding safer, easier, and more accessible.

What’s the difference between 700×23 and 700×25?

The 23s are thinner, lighter (because they are thinner), and a little faster. 25s are 2mm greater in diameter, so they are a little heavier and better on rough roads.

Are 28mm tires faster than 32mm?

28mm tires offer slightly more speed and acceleration on the road, but the improvement comes at a price – a harsher ride and less grip on off-road terrain. 32mm tires make the ride more comfortable and perform better when the surface is less than ideal.

Can 700C tire fit 27?

27-inch and 700C tires are close enough in size that the inner tubes are compatible; i.e. you can use a 27-inch inner tube in a 700C tire, and vice-versa. However, you can NOT use a 27-inch tire on a 700C wheel, and vice-versa.

Are wider road bike tires safer?

In terms of safety, wider tires are less controllable, have more inertion, while thinner tires are more easily get stuck between obstacles. So, the tire width is a matter of compromise, you need to find those which work best right for you, but with experience it may also change.

Does bike wheel size affect speed?

Push bikes with larger wheels can go faster than the ones with smaller wheels because the radius of the wheel is larger they are also more stable at higher speeds.

Are 23C tires faster than 25C?

On the road bike the 23s feel faster, but that may be because they feel harder and you therefore feel every stone on the road. Riding these on rough road coverings can be a bit annoying and they do feel a bit draggy.

What does the C mean in 700x23C?

700x23c simply means the dimensions of your bike tire, under what’s known as the ‘French system’. … The letter c is the width code of the bicycle tire (in this case, width means what you’d see by looking at the bike from either directly in front or behind).

Are 23C and 25C tires interchangeable?

They many not all be a good fit, there is a rim width vs tire width relation you should pay some attention to. But a rim that’s a good fit for a 25C tire will take a 23C tire just fine.

Can I put 32mm tires on my road bike?

Going to a 32mm or 35mm road tire, you will actually DECREASE your rolling resistance. Aerodynamics will worsen a bit, so that is the trade-off, but unless you’re racing, neither of these changes (which even partially cancel each other out) will make a meaningful difference.

Is 32mm enough for gravel?

Width and tread

Your tyre width again comes down to your route and what kind of terrain you’ll be riding. If the majority of the ride is on the tarmac with a few gravel sectors, aim for something between 28-32mm.

What PSI should 25mm tires be?

Road bike tyre pressures

Suggested tyre pressure for road bike tyres (25mm) – for a ≤70Kg rider: Inner tube tyre: 90PSI (6.2Bar) Front / 93PSI (6.4Bar) Rear. Tubeless tyre: 80PSI (5.5Bar) Front / 83PSI (5.7Bar) Rear.
