The tread on a bicycle road tyre has no effect with regards to traction as Ian and Joe have pointed out . Its mainly there as a placebo ( reassurance if you like ) . Some good information on Sheldons site http://www.sheldonbrown.com/tyres.html#tread
Looking at the video I would say it was the white lines that caused the rear wheel to breakaway . Its just one of those things that happens . You could probably do the same ride another day go around the corner at the same speed in the same weather conditions and be fine . Its the road conditions that caused it not the tyres lack of grip

And all three, plus Sheldon, seem to act as if we're cycling on lovely smooth roads with no soft squishy material or irregularities on them... oh and look, Sheldon says that tread helps with those, in the paragraph just above the one being pointed at!

I hope the bike is OK.

has @Fnaar been alerted to the thread title ........

and ouch .

He actually says "Different tyre designs, particularly in the tread, may enhance or degrade traction in each of these cases. " the key words being enhance OR degrade .
As regards to smooth roads he actually says ". If you examine a section of asphalt or concrete, you'll see that the texture of the road itself is much "knobbier" than the tread features of a good-quality road tyre. Since the tyre is flexible, even a slick tyre deforms as it comes into contact with the pavement, acquiring the shape of the pavement texture, only while in contact with the road.

How ya doing buddy hope your healing and well done for getting right back on

Anyway, regarding the OP;

You ain't a proper cyclist till you've chucked a bike down the road.

Like most people with a view on this, I've read Sheldon's comments before. They still aren't going to settle the longstanding disagreement on the effects of tread for real-world road cycling.

 

[Andrew_P]

Just to add to the off topic, I thought it was the compound that altered the grip and rolling resistance?

Dammit really ?
Done it a time or two on a motorcycle so I should expect it any time soon

 

[davidphilips]

main thing is you are ok little bruised and bashed but still fit to cycle, after an accident like that not a single driver stopped to see you where all right perhaps no one noticed?

 

[ColinJ]

I'm glad that there were no serious injuries!

I've got Rubinos on my Cannondale and have not had any problems with grip, even in the wet. It is a case of adjusting your speed according to the conditions!

As pointed out by others above, tread is not going to help on a slippery road. Certain tyre compounds and lower tyre pressures may make some difference, but you shouldn't be pushing it that close to the limit.

Tread is very important OFF-road, when it can bite into soft, slippery surfaces such as soil. You wouldn't want to ride slicks on gnarly bridleways. Conversely, knobbly tread on mountain bike tyres can squirm about a bit when cornering at speed on tarmac so it is not ideal for that.

 

[nickyboy]

Tread is for water dispersal (not relevant for a bike tyre as it is too narrow to suffer from aquaplaning) or grip in the examples where the tread is significant (like CX or MTB tyres) and the surface particularly uneven and soft and as such the tyre cannot deform sufficiently to create grip

I ride Rubinos which have a little bit of tread on them but I know that it provides no additional grip when cycling on the road, just there for cosmetic effect. Basic physics will tell you how friction is created between the hard road and the soft tyre and tread plays no part in this

Good article.

For once.
