Only if you live on race track you will wear out the outer edges of a tyre.

True that..!!

Don't you think that insane cornering on our roads is something pretty much messed up thing to do, when you have potentially every life form on earth ready to pounce in front of you while negotiating a corner..!! Moreover, extreme cornering, leave it to the tracks, it's better that way.

Old = MRF Zapper Vyde @ 15K Kms
New = Michelin Sirac

My previos tyre change looked somewht like this , perhaps pretty much more worn out. Say the inner threads being visible. Changed the tyre that day itself. But i managed to bring some 19-20k kms life out of it.

Here is mine- previous change- Dec 2012

The wear pattern explains everything. If the centre of the tyre is worn out then the Tyre is overinflated. The figure explains more than words.

The presence of chiken strips can also mean that the bike wasn't cornered a lot to wear it down by much. Yes,over inflatig might also cause that, but wouldn't it be uncomfortable to ride with an over inflated tire ?
P.S: mine looks same amount of wear as praful's and i always maintain correct tire pressure.

Hai
Actually cornering in our roads except highway is very less. Overinflation of tyre is definately uncomfortable. But it also depends on the total weight applied in the bike. For example, I weigh 150 kgs and the normal pressure of 33 PSI(recommended by OEM) is way too low for my weight. Hence I maintain a pressure of 37 PSI. This way we have to maintain the balance by trail and error. I have tried this under different pressure condition varing from 35 PSI to 42 PSi. Then I pinned on 37 PSI for my Weight. If my wife accompanies me in my ride I maintain 40 PSI. The best way to do the trials are on the highway. Because you can get a clear indication of the contact area. This is the reason the wear markers are placed at 1/4 distance of the total width of the tyre from the ends. In the photo you can clearly see that the area near the wear markers show still there is life in the tyre. But due to overinflation the centre portion of the tyre is only worn out. I hope I have cleared your doubt. Cheers.

Well genius!! I want to know how did you measure the "few mm" difference between over inflation and correct inflation?

Btw, the image you have used explains for "Car" tyres. Motorcycle tyres have a different wear pattern, because of the entirely different profile they form.

PS: I didn't know 28-30 psi is over inflation

out of curiosity whats the maximum PSI you have used in your bike....
i did 40 PSI in rear(cbr250r) because a person who works in tire factory as supervisor told me to try it and after doing it it gave me thuds as much as it can..i found cornering better but somehow was scared of tire blast(lolz)

My dad was using FZ-S he installed tube of pulsar in it(idea wasnt good at all). last year i was going on highway with my friend in may and suddenly tube and tire got blasted( i was doing 110kmph) we both saved from fall( because of grace of god)+(my friend's weight on rear which didnt let rear tire slip) i know most of us will not believe that we saved from fall on the speed of 110kmph but it actually happened.

Well I am not a genius. I just do trials and error and find the best setting which is comfortable and a pleasure to ride.

It is the same principle. Only difference is that our tyres are having more of a round profile than flat. But with the correct pressure. The surface contact area will be some what similar to Car tyres.

2 PSI will matter if you 60-70kgs. It will be bumpy. For my weight it will not be a matter.

The surface contact area will be never be similar to car tyres & it shouldnt be or else you can never lean your bike. This is where you got it wrong. The tyre profile will always remain round no matter what. So it is impossible to wear out the edges unless someone lives on ooty, valparai, kari motor speedway etc

or if the tyre is severely under inflated.

I say lets drop this discussion. It doesnt help anyone in anyway & it is always better to stick to manufacture recommended tyre pressures.

The FZ's tyre is nowhere comparable to pulsar's tyre, as fas as the tube is concerned, tubes are not so reliable as the tubeless tyres. The tyre n tube have a specific combination, fz tyre is way too broad to use a pulsar tube. Its not just the tube, depends upon the pressure, if the tyre was ruptured or repaired previously by some local puncture wala. Tubes work fine on highways, u have to b very careful when u put a tube in a tubeless tyre. I know i speak a lot. Lollzzz. The good ur safe n no ones hurt. Ride safe!!

Now that seems like whoaa..... I saw the same VYDE same place same road everything same...even that silverish mark....except the tread on google.

SPEAKING ALOT BUT WITH KNOWLEDGE IS GOOD FOR OTHERS Thanks and will try not to repeat experiments like this...
yup it got punctured and thats why dad installed tube in it.

Well I apologize for the comparison between car tyres and bike tyres that was given by me. No heart feeling.

Hey, there is nothing to apologize for man! All of us are learning here

When i bought my duke last year around april, within one month i got a puncture in my rear tyre. The nail had gone till the rim of the tyre and air was leaking near the rim. The SVC guy told to replace the trye as the puncture couldnt be repaired near the rim. I told the tyre hasn't even done 1k kms. So he adviced to put a tube inside that. Since then one year is over and i havent faced any problem. i have done around 15k kms till date.

Reading tyre blast thing got me worried. Could you explain what risks are there if we put a tube in tubeless tyre.?

Anyways a tyre change is around the corner for me, so not worrying that much.

Well, maybe from my blog. I have used this image in my blog for my reviews and stuff. So that might be the reason. And you might have seen the new tyre i got from there as a replacement..lol...

Is this by any chance the one you saw ?
