The folks over at Conti-Online in Germany have archived this epic tire test/review and is available as PDF download.  The test was conducted by the German Cycling magazine TOUR way back September 2007. Old data but still valuable information.

The test criteria includes, but is not limited to, rolling resistance, puncture resistance and grip. This is the most comprehensive Road Cycling Tire test we have ever encountered so far and is definitely worth the download! The folks from TOUR used a special test rig to push each tire to it's absolute limit, culminating in the test rider losing grip! SEMPLANG!

The Continental GP4000s emerged as winner. Based on first hand experience, these tires are quite hard to fault. Light enough for racing, tough enough for touring and training.... more than jack of all trades. 

Clincher honor roll: 

  1. Continental GP 4000s - 1.0
  2. Schwalbe Ultremo - 1.2
  3. Michelin Pro 2 Grip - 1.5
  4. Michelin Pro 2 Race - 1.8
  5. Continental GP 4-Season - 2.0
  6. Schwalbe Stelvio Rain - 2.2
  7. Hutchinson Fusion 2 RoadTubeless - 2.4
  8. Hutchinon Fusion 2 - 3.3
A surprising finding in the test is that top line clinchers are better than the best tubulars. See for yourself!

  1. Hard to compare apples to apples as it wasn't in the list :)

    Based on experience, the Kalientes are a decent training/light racing tire as long as you stick to clean roads. Light Weight at around 200g flat. However the rubber compound seems to fancy picking up broken glass bits which can eventually end up as a puncture.

    Sidewall protection is not that great as I had mine slashed, exposing the tube. I think I rubbed the sidewall on a rock.

  2. Was happy i bougth the correct tires

    1. same here Christian! although for long rides in the middle of nowhere, I'd still go for the Conti 4 Season. For everything else, definitely GP4000s

  3. How many kms do i expect my gp4000s to last?

  4. hard to say exactly; it would depend mainly on the road conditions and to some extend, your setup weight (bike, gear + you).

    Longest I spent on the same pair of tires was with my pair of Conti 4 Season. I think i managed 2000kms on those before noticing any wear! By then, i just found some 'squaring off' on the rear (as opposed to rounded when new). But i sold them off to get the 4 seasons along with a wheel change.

    anyways, some reports on the internet indicate heavy wear at 4800kms for the 4000s. pretty tough!
