Readers ask: What Size Road Bike Tires Should I Use?

What is the best size tire for road bike?

Most road bike frames can accommodate a tire as wide as about 28mm. Cyclocross and touring bikes are generally designed to accommodate wider tires. We recommend 23mm and 25mm wide tires for recreational road cyclists. The 25mm width is nice for long distance riding since it will provide a more comfortable ride.

Are 28mm tires faster than 25mm?

(based on the same model of tyre). Going wider, a 25mm tyre will only need to be inflated to around 90 psi to get the same rolling co-efficient score! Daring to go further, a 28mm tyre at 80 psi shows a similar co-efficient to the narrower tyres.

Are 28mm tyres more comfortable than 25mm?

Most road bikes come as standard with 23mm tyres, most come with 52 tooth outer chainrings. Both of these things are pretty useless for everyday road riding. Get 25mm tyres, or 28mm if your brake and frame clearances will allow. For most riders a wider, but still lightweight tyre will be faster and more comfortable.

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.

Are skinny bike tires faster?

Most road bikes and touring bikes have thinner tires, while mountain bikes have big fat tires. A firm thin tire on the asphalt surface won’t flatten much. The less the tire flattens out on the bottom, the less surface area is in contact with the road. Less contact in this case means less friction, and more speed.

Is a 28 inch tire the same as 700c?

The tyres can differ, but the 28”, 700C and 29er are all the exact same rim diameter. The 700 markings will be followed by the width in mm, and the 28 or 29 markings will be followed by the width in inches. This is the most common wheel size, so look out for familiar markings (such as 28×1.

Are 28mm Tyres more comfortable?

It’s not as simple as lobbing on a set of wide tyres though. Go to a wider 28mm tyre and drop the pressure to 80psi, and again you’re looking at the same level of rolling resistance. As well as improved rolling resistance, a wide tyre at low pressure also equals more ride comfort.

What size tires do pro cyclists use?

While 23mm was the pro standard not so long ago, this year 20 teams are using 25mm tires for non-time trial stages, and the other two Specialized-sponsored teams are using 26mm rubber. Continental remains supreme in the Tour peloton, with nine of the 22 squads racing on Competition Pro LTD tubulars.

What does the C mean in bicycle tires?

The letter “C” in a tire’s parameters refers to an archaic French standard for bike tire sizing which relied on letters ranging from “A” to “D” to indicate a tire’s width and subsequently the circumference of the corresponding rim.

Do wider tires ride better?

As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car. When changing the car’s original wheels and tires, the general rule of thumb is that you can go up or down by one inch.

Are wider tires better cycling?

Tires with a smaller diameter have a higher rolling resistance with the same inflation pressure, because tire deformation is proportionally greater. The tire is flattened more and is “less round”. Wider tires roll better than narrower tires.

What is the best psi for road bike tires?

Tire inflation basics A typical road tire should be inflated to something between 90 and 120 PSI. Mountain bike tires, on the other hand, tend to run at much lower PSI.

How much slower are 32mm tires?

And a 32mm tyre is only about 2 watts slower than an equivalent 28mm tyre.

Are wider bike tires faster?

Not only do wider tires roll faster, but they’re also more resilient, comfortable, and aerodynamic when paired with the right rim. At the start of each new year, professional teams provide their riders with a supply of clincher tires and tubes to get them through a season of training.

Do bigger bike wheels go faster?

We found that all wheel sizes roll at the same speed on road surfaces. This contrasts with mountain bikes, where a similar study has found small, but significant, speed benefits for larger wheels.
