Fascinating Article on Tire Testing

Part of a series I'm calling Tires 101 with lots of great info to consider when looking for new tires. 


Our choices in the tires we ride are possibly among the most subjective we make. There is often very little empirical data (except maybe price...) that is involved. More commonly our "data" is along the lines of "my buddy says they're the fastest tires he's ridden" or "she said she didn't get flat tires for a year". When  you really stop and think about it though - there is a lot of highly personal variables involved in those statements. Let's cut through the clutter.

I've long admired's James Huang's technical writing and referred to it often as the best in cycling journalism (although - VeloNews has really stepped it up lately).

One of his latest pieces highlights a tire testing facility in Finland that seems to finally be coming up with some good data on tires in real-world type scenarios and less-so in the controlled laboratory conditions of older tests.  The article has some fascinating facts and data; confirming some long-held thoughts and theories of my own and surprising me on a few areas that I had accepted as fact which it seems were not.

     -Wider tires are faster due to less energy lost in casing deformation.  The study specifically cites 25 mm tires versus 23mm tires.
