>>1211426Because most 28 mm tires sold commercially are puncture proof or cyclocross tires and have stiff horrible casings, so they are slow and have a horrible ride feel. Try to get with the program chan-tard. 23 mm road bike tires meant for racing usually have much softer, supple casings.

Especially if you ride mostly on pavement, you can experience 80% of the benefits simply by switching to supple high-performance tires in a size that fits your current bike.A 28 mm tire from Compass Direct with a supple casing will absolutely outperform its 23 mm counterparts though. The German magazine Tour which does the most testing of tires recently wrote that Compass Direct Tires were one of the fastest they tested:

>The reason is simple: TOUR tested without a rider on the bike. This measures the hysteretic losses in the tire, but it neglects the (much more important) suspension losses that occur as the rider’s body and bike vibrate. See the attached photo for a graph.
