What is the difference between 700×28 and 700x28c?
The more likely scenario is that they’re same thing. Most times, the ‘c’ is vestigial, either referring to the rim diameter (look up old French tire sizing if you’re curious) or meaning the tire has a ‘crocheted’ bead meant for use with hooked rims. In either case, we don’t do that anymore. The term “700c” is the tire size according to the French system. The “700” is stating the diameter of the bicycle tire and “c” is the width size of the tire. However it’s not 700 millimeters it’s 633 millimeters. Also, another common mistake is that often riders confuse “c” with centimeters.The C-Type tire, on the other hand, is specifically meant as a commercial-rated tire, with a higher load rating for a given size than many LT tires. These C-Type tires will show the letter “C” immediately after the wheel diameter in the tire code. Example: 225/75R16C.
Are 28 tires the same as 700?
Is a 28 inch wheel the same as a 700c? Tyres in 28″, 700C and 29″ sizes have exactly the same rim diameter. The designation 700 is followed by the tyre width in mm and the designation 28 or 29 by the width in inches. A: 700x23C & 700x28C are the same tire sizes (diameter). The 23 & 28 denote different tire widths, not tire diameter. Both of these will fit the same diameter rim (700).All modern road bike tires are sized as 700C and typically vary in width from 23mm to 32mm. C tires meant for paved roads that are wider than 32mm wide usually are designed for commuter and hybrid bikes. The standard 25mm width offers plenty of grip, rolls fast, and weighs much less than beefy mountain bike tires.Road bike tire FAQ It all depends on your practice. A 700×25 tire is ideal for a good compromise between comfort and performance. A 700×28 provides more stability, while a 700×23 favors speed.Rolling Resistance: Narrower tires (like 28c) can have lower rolling resistance on smooth surfaces like a well-paved road. This means they require less effort to maintain a given speed. In comparison, wider tires (like 32c) may have slightly higher rolling resistance due to their larger contact patch with the ground.The results are always the same: There is no measurable difference in how fast the three common wheel sizes (26″, 650B, 700C) roll on real roads – paved or gravel, even cobblestones – as long as you keep the casings, tread and other factors the same.
Is 28 inch 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. If your wheels are 700c, look for a tyre width of between 28c and 35c. If your tyres are 26 or 27.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 30mm tires faster than 28mm?
Aerodynamic Drag In testing: 28mm tyres were ~1W faster than 30mm at 45km/h. W more drag than 25mm. But that drag penalty disappeared on rough roads, where wider tyres rolled faster and more efficiently. You might be surprised to learn that wider tires can have lower rolling resistance than narrower ones—especially at lower pressures. A 28mm tire, when inflated to the appropriate pressure, deforms less vertically and more radially, allowing for a larger contact patch and improved energy efficiency over rough surfaces.Aerodynamic Drag In testing: 28mm tyres were ~1W faster than 30mm at 45km/h. W more drag than 25mm.Wider tyres, however, have a larger contact patch with the road, which increases rolling resistance and aerodynamic drag. This extra resistance means the engine has to work harder, consuming more fuel.
What is the best rim width for a 28mm tire?
Optimised Rim Widths For 25 – 28mm tires, inner rim widths of 20 – 22mm are optimal. For 30 – 32mm tires, inner rim widths of 24mm provide the best results. The 105% rule says that the external rim width of your wheel should be at least 105% of your tire’s actual measured width. This ratio allows the airflow to remain attached as it moves from the tire onto the rim, reducing drag and making your bike more aerodynamic.A commonly cited guideline is the 105% rule, where the rim should be at least 105% of the tire’s width to optimize airflow. Poor matching can create a “lightbulb” shape that catches wind and increases drag, even if the tire itself has low rolling resistance.It has often been said that to have good cycling wheel performance, there is a rule that the external rim width of a wheel should be at least 105% of the width of the tyre, or that there is a simple relationship/formula that will predict the aerodynamic performance of a wheel based on rim width vs tyre width.
What are 28mm tires good for?
Choose 28mm if you value comfort, ride on rougher roads, go on long-distance rides, or want lower rolling resistance on varied terrain. Wider tires excel in variable conditions. For smooth race courses, 28mm tires strike an excellent balance between aerodynamics and comfort. For rough roads, gravel sections, or all-weather riding, 30mm or wider tires provide significant advantages.
