Continental GPs near end of life; Going to try Michelin Pro4s next.

Over the past 4 or 5 months I’ve put right at 3,500 kilometers on my Continental Grand Prix 4000s (700×23) clincher tires, and they are going to need to be replaced soon. The back tire is squaring off, and its wear indicators are nearly gone. I think if I rotate the tires I can eek another few hundred kilometers out of them, which would put their usable lifespan at around 4,000 kilometers. I’ve seen reviews in which cyclists claim to be getting more than 11,000 kilometers (7,000 miles) out of these, but I don’t see how!

I have still not suffered even a single flat on the Grand Prix 4000s tires, and I really like their overall performance, feel on the road and how they corner. My instinct is to order another pair of the Grand Prix tires, but I think I’m going to give another tire a try….

Michelin Pro4 Service Course Tires

Michelin Pro4 Service Course Tires

Awhile back the Michelin Pro4 Service Course clincher tire was suggested by a JSF member and, based on the reviews I’ve seen, it looks like another excellent choice. The Pro4s are a few grams lighter than the GPs, and some claim the ride quality is a little nicer than the GPs. Flat resistance is reported to be excellent, and that is very important to me.

I think I’m going to give the Pro4s a shot. As you can see, they are available in a bunch of colors. I like the all-black look, so I’m glad that’s available.

If any of you have used the Pro4 tire, I’d love to hear your thoughts!

  1. I made the same switch 2 years ago. I got about 2500 miles out of the rear before I got a flat and about a 1/2cm gash in the tire towards the end of the season this year. There was a lot of debris on the road where I got the flat, so I could have just been unlucky.

    The Michelins absorb less shock than the Continentals, but they feel like they roll a bit better. I also have better cornering confidence in the Michelins. Another thing I noticed is that the rubber wears better. It takes me about 2-3 years to go through a set of tires and in that time the Continentals were cracking and had threads coming loose on the casing. The Michelins have a small amount of cracking, but no threads coming from the casing after 2 years.

    • Excellent feedback, thanks very much.

      I’ve read in several reviews that the Pro4s feel like they absorb more road bumps than the GPs, so your contradictory observation is surprising. I guess I’ll know what I think soon enough!

      Everyone seems to agree that the Pro4s are outstanding performers when it comes to cornering, which is very cool.

      Should be an interesting trial. The GPs set the bar high, so the Pro4s are going to have to be exceptional to get me to switch.
