Deacon Mark Supposedly they are not supposed to have the same braking traction in the reverse direction. My complaints with them is that they wear so quickly. They DO have great traction but I don't think that it is any better than the Michelin Pro4. I have also used the Michelin Power Endurance and they work well too. But the Pro4's have a more reasonable price and don't wear so quickly. Another datapoint. I recently replaced the rear Continental GP5000 tire (32 mm version) after the first flat after 5500 km. Best allround tire IMO. I must admit that I seldom pay attention to the mounting direction mainly because I'm too lazy to look for the hard to see arrow in bad light conditions in my garage. Well, My 28 mm tires take forever to wear out. So I don't think it would be unusual for a 32 to wear forever. The Conti's that I was using for centuries were 25 mm and they lasted about two months per pair. That would be about 1,500 miles That's about 2,500 KM but other tires wear a great deal longer and so i often don't inspect the tires until I start getting flats. |

[directional markers on tyres] They are there so people don't ask the manufacturer which way to mount the tyres. Of course instead they get question whether the direction is important. -- Note: please read the netiquette before posting. I will almost never reply to top-postings which include a full copy of the previous article(s) at the end because it's annoying, shows that the poster is too lazy to trim his article, and it's wasting the time of all readers. |

Lou They certainly feel good so far. I’ll see how they last. Shark fins tell you the direction. |

"Off road, the rolling direction is far more important, as the tread ensures optimumconnection between the tire and the ground.

That is why certain tires are fitted in opposite rotating directions when used as front and rear tires. "There are also treads without a specified rotating direction." -- - Frank Krygowski Even off-road directional rotation doesn't make much difference - you have to really push the limits of the tire in order to realize a difference, which is generally much more aggressive than any non-racer would attempt. I remember an article in velonews probably 20 years ago where an engineer for Specialized was interviewed on this very subject. He said choosing the right tread for the terrain is vastly more important than being concerned about the direction of the tread. He even gave the idea of front/rear specific off-road designs a big "meh". |
