I am not sure about the exact depth of the crack. Initially when i checked in a puncture shop(BP bunk) there was no leakage in this crack. But today when I took the car to MASS they were able to find the leakage. I will check the air pressure after a week to find whether the puncture is fixed or not and then decide to put a tube.
I do highway drives frequently hence as mentioned by you even if the puncture is fixed I will be using it as stepny only.

That is the best thing to do. My principle is "Never ever compromise on tyres". Even if you have the slightest hesitation, go for a new tyre. Remember tyres are the only part of the car which maintains the contact with the road. Your life is far more worthier than a couple of grands on a new tyre.

Unhappy Re: Punctures in tubeless tyres.

I found that my brand new Ford Figo had a flat tyre. Hardly 1500 km from delivery, it was painful. I changed the wheel and took it for repair. The tyre repair guy found a 3" headless nail that was filed at an angle to make it very sharp. I have a memory of seeing such nails only in cities. Makes me wonder if someone goes around dropping such nails on the road. Would hanging a magnet in front of the car, attached to the bumper prevent punctures? Any ideas folks? ?

Bumping up a very old thread with a question I think is relevant to this forum.

How many punctures can a tubeless tyre take before it is considered unsafe for use. One particular tyre of my A-drive has had 3 so far, off which only one was due to a nail, one was so minute that tyre shop was not sure if there was a puncture, but the tyre was loosing air regularly and the most recent one, again no nail, but there was substantial air loss and this was more easier to find. I am now beginning to wonder how much longer to use this particular tyre. Experts, please advise.

dass,
It is not the number of punctures but the position, type and extent that matter more.
Say for example that a tyre has 3 punctures in the tread area at different positions that are easily repaired without the need of large patches, they would hardly have any effect. On the other hand a single serious puncture / tear on the sidewall would call for a replacement.
Furthermore, even on the tread, tears are more critical than pin holes.
In other cases, 2 punctures may be close by and could make for a possible replacement case if it fails repeatedly (cause the punctures to reopen).
It is also important to observe other damage a tyre may have sustained due to being driven while punctured.
There is also the case of bulges on the sidewall, wherein I feel the tyre must be replaced.
Then again, shoddy repairs may cause an unbalanced rolling and again call for replacement.
In some cases, people throw in a tube and believe all is hunky dory, but this is not the case. I would suggest that the tyre be replaced.
All said, the simple solution is to inspect the tyre properly and you will certainly find the logical answer.
