What size tire is 700x25c?
700x25c indicates a tire with a 700mm outer diameter and a 25mm width. A third type of tire size might appear on either a mountain or a road tire: 25-622 is the International Standardization Organization (ISO) way of identifying the 700x25c tire in the example above.
Can I put 25mm tires on my road bike?
Well, for a start they won’t fit in most road bikes; a few still struggle with 25mm tyres. Second, a super-wide tyre wouldn’t work aerodynamically with existing wheel rims. And third, wider tyres would add to a wheel’s rotational weight and dull the acceleration.
Are 25mm tires faster than 28mm?
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.
What size tire is a 25C?
Tire Size Chart

What does 700×20 25C mean?
700x25c is the dimensions of your bicycle tire, using the ‘French system’. Let’s break it down. 700 is the nominal diameter of the bike tire, sized using millimeters. The next number, 25, is just the width of the tire (this is also measured using millimeters).
What size tires can I put on my 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.
Which is better 700×28 or 700×25?
You will not notice the difference between 25 and 28. Tire pressure and tread pattern are far more significant in terms of rolling resistance, and the difference in diameter/gear ratio is too small for you to feel.
Do pro riders use 28mm tires?
For several years we’ve heard of their lower rolling resistance, and experienced firsthand the improved comfort & grip of larger road tires. But pro roadies have been resistant to change. That time for change seems to have come, as 28mm tubulars become de rigueur in the peloton of the World Tour.
