Anti-Puncture Tyres At-a-glance

In the dry, and on a smooth(ish) surface, I agree with this. But on irregular durfaces, I disagree with this entirely. Simply harking back to what Sheldon Brown said, means an abandonment of individual, critical thought. If you are happy to just join the herd, then that is you.

Slightly dimpled, or mildly patterned tread do, I believe, provide increased grip in mixed and irregular surfaces. I do not make tyres, nor design them, but I have given you (the herd) food for thought.....to opt to criticise the designers/engineers from Vittoria and Veloflex. If you think their understanding of tyre dynamics is inferior to that of Sheldon Brown, then you my friend are so deep in the herd mentality, that you cannot be reached.

Mixed surfaces are a completely different matter and tread will help if the surface is soft. We are talking about hard but wet surfaces here. Whether they are regular (smooth) or irregular (bumpy) they are still harder than the tyre material.

And I would rather you use someone like Mike Burrows than Sheldon Brown. He explains it quite well in his Bicycle Design book.

What is it that leads you to believe that a mildly patterned tread is better on a hard but irregular surface? Can you not see the amount of rubber is reduced and how do you think the tread will increase grip while decreasing the rubber in contact with the road?
