@lostsoul: No motogp tyres won't be slipping. But, then you will have to change the tyre every time you go out for a G2G.

R15 tyres won't be providing any grip if they are bald. The tyres for the street bikes are made out of hard compound. It is the elasticity of the soft Motogp tyres that maintain the grip. You should stop comparing motogp tyres with our normal ones.

Ok thanks guys . i modify my query now . if the R15 soft tyre gets worn out and wear is totally even will it provide better grip in clean smooth roads ?

why would the motogp bike's slick tyre be all over if roads are clean and dry and smooth ?

I had said Indian road conditions. They are not always clean and dry and smooth.

To answer your query, it will not provide better grip, but it won't be slipping too. But the wear will not be even unless you do as much riding leaning the bike as much you do riding straight. New stock tires provide best grip.

+1. They are made for a different purpose than the tires we find in our machines.

The tyres wear in motogp is different from street tyres due to compound and the extreme condition they are subjected to. motogp tyres will start graining within couple of laps. While street tyres will wear more smoothly or evenly. But then such wear will occur only after several months/years and by then, natural elements such as sun, rain etc will take its toll on the tyre effectively degrading the rubber quality. So the street tyre rubber, at this point will not perform as well as a new rubber. Ever played table tennis? Old bats simply refuses to spin the ball as the rubber has degraded and lost all its grip.

IF and a big IF the road is as good and clean as a race track, then in DRY condition, motogp slicks will perform as well on the road as on the track.

Bhia Galti ho gai...
i literally meant that they add some more carbon to it make it harder..and reduce it if they have to make the rubber soft and more sticky as the carbon is the content that absorbs heat while the tyre is running, the more carbon, the less the grip, the more ruber, More and Better Grip.

A Hi-Five on that!! That explains it all!

An Dual Purpose tyre,that too soft compound.. i thnk you are mistaken my frnd!

no sir..... indeed thats wat the company salesman tol me as wel..... i thot maybe i must have heard it wrong in the fren circle... but wen i heard it from themselves i was pretty sure of it...

plus the grip pattern n its hold on road...i find it pretty like the r15 slicks ...only a big fatter ... *goes wit the personality u knw

Am using ceat vertigo(tubed) on my unicorn for the past 1 year,done 10000+km.Am satisfied with the grip(touchwood)

My R15's tyres have run abt 19K KMs now and both front and rear have worn off in a similar way. By the looks of it I guess I can run them for another 3-4K KMs. The groves are still seen and the TWI is yet to show up. But compared to a new tyres they are like almost worn out.

I am yet to realize any loss of grip from those tyres. I feel them to be as grippy as they were when new. Yes, I keep trying other's new R15's on and off.

I am not going by Anyone's Word Dear.. I am saying tried and tested practically,
I think you are a bit diluded with the information somewhere,My freind!

Explantion by an Engginer in Bristol University in UK on the Website: www.chm.bris.ac.uk

The compound of a racing tyre describes the particular blend of materials that went into its construction. Over 150 different components are used in the manufacture of F1 tyres but the main ingredients are rubber, carbon and mechanical oil. Varying the relative amounts of these three components will produce different tyre compounds, which will each have different characteristics.
For more details of the manufacturing process of F1 tyres, click here.
Much development work is carried out by the tyre manufacturers (Bridgestone and Michelin) into their tyre compounds but it can often be a hit-and-miss affair (it has even been referred to as striking black gold). This is why the recipes for tyre compounds are such closely guarded secrets.
Compounds are often described in terms of their "hardness" or "softness". This does not mean literally how hard the tyres are to touch, but describes how the tyres behave on the racetrack. Harder compound tyres will be more durable than softer compound tyres, meaning that the driver can complete a greater number of laps before the tyres lose performance and they are forced to make a pit stop. However, the harder compounds will provide less grip than the softer compounds, meaning that the driver will not be able to go as fast on each of the laps they make. The choice of tyre compound is therefore a compromise between durability and grip. Choose hard and you'll be able to stay out longer than your competitors. Choose soft and you'll have to pit earlier in the race but you'll be going faster than they are and may be able to make up the difference!
The physical explanation of the difference between the hard and soft compounds is the degree to which the rubber molecules interact with the track surface.

The diagram shows how a hard and soft compound tyre interact with the track surface and hence how much better grip is generated by soft compound as they have more of rubber and less of carbon.
The hard compound tyre has a greater number of cross-links between the long rubber molecules (introduced by Vulcanisation). This restricts the length of the rubber molecule that can interact with the track surface. Less interaction between the rubber molecules and the surface means that the tyre has less grip on the track.
The situation is exactly opposite for the soft compound tyre. It has far fewer cross-links and therefore a greater length of rubber molecule that can interact with the surface. Greater interaction means greater grip.
Note: The above assumes a perfectly smooth tyre and a smooth track surface. In the real world this does not occur and some degree of the "grip" generated by the tyre is a result of the interlocking of microscopic imperfections in both the tyre and track.

i'm lookin for tyres for my p220..

cant decide between sirac and vyde..

heard sirac is heavier so it'll affect acceleration..plus it looks HUGE...

i wanna know..how much difference there is between vyde and sirac,in terms of grip,(for me confidence while cornering is top priority !)

is sirac worth the loss of acceleration ??

plus since vyde has a rounder profile..is cornering EASIER on it ??

also which front tyres are good for the 220 ??

thanks in advance..

thanks for a quick reply..but please could you give me some specific reasons ...
would be a great help to clear any doubt in my mind..
