4 maj 2019 · Road Bike Wheel and Tyre Diameter and Circumference Table. I'm always looking for dimensional data for rim and tyre combinations, especially when setting up cycling computers and analysis software so I thought this table might be useful.
Tire Circumference Chart. Please use this chart for your reference. Tire size is shown on the side of a tire. Tire circumference may vary depending on tire pressure. ETRTO. Tire size.
The thickness of the tire is measured across its tread, while the diameter of the rim is measured up to its bead. Both are measured in millimetres. A marking can also be found printed on the sidewalls of the tire.
12 sie 2015 · Here, I’ve explained how you can read and understand bicycle tyre size marks (why and how 700 C is the same diameter as 28″ x 1.75 or 29″ – all being the same 622 mm diameter tyres). I’ve also explained which tyre widths you can fit on your rim and bicycle frame (and how to measure your rim width and frame tight spots).
Here are the measuring methods of the three most common markings used today: Guide on how to read bicycle tire specifications and how to choose the right size to fit your rims. Convert between ISO/ETRTO, English, French standards.
That’s how the diameter and circumference (circ – equals distance rolled in one turn of the wheel) are calculated in the Tyre size table. These figures are useful for setting your cycle-computer and precisely calculating gears.
