Alright-time for some roll down testing. İ think İ'll need a power meter, can CXM spare one for the test? :D

<p>i guess it's too hard to generalize without specific tires, widths and pressure. interesting link - but i guess what c-note was asking isn't possible to extract from that article exactly:</p>
<p>"A direct comparison is impossible though, as the tires have different widths and some are used with very different inflation pressures."</p>

<p>but many tests show that width just widens the contact patch while a narrow tire lengthens it, so not much difference, and if anything wider can…</p>

<p>but many tests show that width just widens the contact patch while a narrow tire lengthens it, so not much difference, and if anything wider can be better. so with a smoother tread, you may be faster on both accounts. of course, there has to be a limit. a 2.5" smooth tire having less rolling resistance than a 25c? that'd be surprising.</p>

<p>c-note - how about some testing? i'm sure readers would be interested...</p> http://www.schwalbetires.com/…tag:cowbell.cxmagazine.com,2011-05-16:1198434:Comment:908712011-05-16T00:40:59.730ZAndy Gorskihttps://cowbell.cxmagazine.com/profile/AndyGorski
