Unless you know of a road which is made of Formica or porcelain, you're talking out your ass. Despite the fact that tread on road tires is almost entirely counterproductive, there are a few rare instances when one can notice a difference. These are times when a comparatively smooth surface is lubricated with a complementary liquid. Glossy polished stone, for instance, can be effectively lubricated with clean water. Steel plates and rails can be effectively lubricated with dirty water. Smooth asphalt can be lubricated by silty runoff, and even sanded concrete or pebbly asphalt can be lubricated by algal slime. A heavily siped or compact block tread can still slip in the aforementioned conditions, but it must be pushed harder than a true slick. I believe this as due to a squeegee-like action at the leading edges in the tread. Choosing a tire based on uncommon surface conditions that are better to avoid entirely may be a mistake for most of us, but it is something to consider if you live and ride in a slime-covered hell. In that case, it's also a good idea to be conscious of the differences between tread compounds (which most of us needn't worry about except for wear resistance). I can hear and feel the small amount of sideslip that characterizes a treaded street tire in comparison to a slick one. I prefer not to have thin, easily punctured spots in the tread rubber, which is an intrinsic characteristic of siped and treaded tires. And I find it frustrating that treaded tires pick up little rocks and bits of debris that slicks don't. These are the reasons I use slicks when they are available for my application. But I acknowledge that under certain marginal and unpleasant street surface conditions, even a small and useless-looking amount of tread can help a little bit to maintain traction. Chalo |

No, the extra resistance on a patterned tread comes mostly from the tread blocks moving around under load. This (among other things) causes them to wear faster, because they absorb more energy. The pattern picks up debris more than slick rubber, so without reinforcement, you get more punctures. The contact patch of a bicycle tyre is small enough that it IS the tread pattern. Racing tyres do not have tread blocks. *Those tyres that have "blocks" do not quickly wear out the pattern. *A thicker tread will almost always absorb more energy. *That is the trade off with a long tread life. *A racing tyre tread does not have vertical cuts in the tread, the pattern is at 45deg to the surface. *It may take quite a while before the centre of *a patterned racing type tread is worn in the centre, still providing the grippy patterned tread towards the edges for cornering.

I trust you have no evidence to contradict that the best patterned tyre outperforms a slick tyre in wet slippy conditions. TJ |

Just a few places I have fallen or experienced a lack of adhesion due to a lack of tread when wet. Roundabouts - diesel/oil deposits Brickworks - clay Tramlines - polished steel Railway level crossings - polished steel Cattle grid - polished steel Fords - algae Manholes and drainage grids - polished iron Car repair shop - diesel/oil Cobbles - round 4-5" stones Setts - flat polished granite Manholes and drainage grids usually end up with a dressing so are not so much of a problem. All the other hazards remain. I also enjoy the opportunity to go off-road because I can. An unpatterned tyre will take away that last moment decision to have a bit of fun on an otherwise mundane journey. TJ |

Which of course reminds me, those that use non-patterned tyres, tend also not to use mudguards so tend not to ride in the rain. They therefore do not have the experience of how to cope with bad weather and are not the people to ask. TJ |

This is what Chalo wrote: "I prefer not to have thin, easily punctured spots in the tread rubber, which is an intrinsic characteristic of siped and treaded tires. And I find it frustrating that treaded tires pick up little rocks and bits of debris that slicks don't." He is referring to the rocks and debris that gets stuck into the sipes and treads of treaded tires and therefore causes them to puncture more often than slicks. Slicks have no weak thin spots between the tread for the rocks and debris to stick and puncture. He is not referring to the tires throwing the rocks and debris onto his legs as he rides. Which a fender would prevent. |
