Tyres on the wrong way for over two years

My head displaces water better without hair

No, I don't think a slick tyre would displace water in the same way that a treaded tyre would.

What does the tyre tread do?


On a normal, smooth road, the tread has only limited influence on the riding properties. The grip generated by the tyre on the road is almost exclusively the result of the rubber compound.

Unlike a car, a bicycle will not aquaplane. The contact area is much smaller and the contact pressure is much higher. The floating effect of aquaplaning could only theoretically be achieved on a bicycle ridden at speeds over 200 km/h.

Off road though, the tread is very important. In this situation the tread establishes an interlocking cog-like connection with the ground and enables the transmission of all driving, braking and steering forces. On rough or dirty roads, the tread can also contribute to better control.

My kojaks have no tread. They work fine in the wet.

How is this possible without tread? Discuss.

Not going to discuss an anecdote which is biased.

Yeah, I like some tread for biting quicker through mud/mulch. It might mean they throw the water off differently, but it's not needed for gripping through water at bicycle speeds and pressures.

I initially responded regarding a tread pattern on a tyre displacing water. Others have bought in aquaplaning.

Tread patterns are there to displace water and thereby increase the speed at which aquaplaning occurs on tyres that have a combination of factors ie. low enough contact pressure, large enough contact area with the road surface or high enough speed to induce it.
Bicycle tyres achieve none of the above criteria; tread is only there for aesthetics.

I've only ever made the point of a treaded tyre displacing water, nothing about aquaplaning.

No, I'd still say that a treaded tyre displaces water.

Do you, or anyone else, have any evidence that tread is necessary on road bike tyres?

Yebbutt you want to displace water to prevent aquaplaning - which will happe if you can go fast enough,which you can't

The above is not the issue here.

 

[Tanis8472]

Of course it does. You have not, however, quantified how much.

An untreaded tyre displaces water. A tyre made of smooth steel would displace water.

Where is all this stuff about aquaplaning coming from?

Where have I said anything different to the above?
