Tyre slick formula 1

[Viper5]

Wow this was an interesting debate I started.

Well now I know unless I'm travelling at Mach 1 on the bike with a mahoosive slick tyre with no tread in the wet I should be ok.

This is interesting (quite a few treads on show):

From that link "On rough or dirty roads, the tread can also contribute to better control."

Ah, but what do Schwalbe know vs the might of the CC experts?

"just 65 PSI" cracks me up. On vintage road bikes with 27x1⅛ or 1¼", that's not unusual, is it? What goes around comes around...

As I had mentioned in a previous thread, I did try to get in touch with Schwalbe, to ask them if they could identify the engineering principles to substantiate their marketing teams claims, and provided them with information with regards to current understanding of friction. They refused to comment.

Specialised:

I did some research on this topic. Still no data to back up the claims for road tires, but the picture gets clearer. Common perception is that tread has no influence in road bicycle tires. But this is not entirely true. The question has to be how much tread do you need?

Does tread have an influence on traction in road bicycle tires? Yes. Tread does have an influence on traction in road tires. Tread, if it is not so high that it lifts the tread ground off the road (<0.2mm), helps sink tread rubber into rough road surfaces and penetrate lubricants (water) or dirt. Peaks in the tread increase press into surface crevices and add contact points between the road and the tire, and thus increase friction. Just a roughened or scuffed tread surface passes as a tread already. It does not need to be designed shapes.

Challenge Handmade Tyres:

Tread design on a road tire is like the cherry on the icing on the cake. A slick tread will function on any dry road surface, but once it gets wet, a herringbone tread pattern like on our Forte, Strada, or Paris-Roubaix tires will help channel water outward while slightly deforming and again, maximizing tread contact. Traditional patterns like the herringbone are the most effective and do help in most conditions. The small grooves of a herringbone help the compound to drain the water, and the small rubber wings that come up can flex and deform to optimize grip. A Forte pattern with the deep fine “S” on the side has proven to be a very good tire in wet dirty conditions when used by Bretagne-Séché and Team3M.

Continental:

Tread patterns are largely aesthetic, and although they provide texture that can aid traction both wet and dry,

Vittoria:

a well thought-out tread design increases its contact area when turning, accelerating, and braking (increased load due to force will flex the diamonds and grooves) and will also provide micro interlinking in between tread pattern edges and road surface grooves.

Of course, tyre manufacturers have no interest in selling you multiple tyres for different seasons.

I know - but they have done a *loody good job of selling non-aquaplaning slicks over the years so who can blame them.

Why would they? The time spent changing tyres is time not spent wearing them out and buying more sooner.

I think you may have missed a bit of sarcasm in my post you quoted?

I assumed you were being sarcastic despite not marking it as such. Maybe you missed that?

Are you being sarcastic now?
