Gents there are many types of imports going on with tryes.
Some tryes get deshaped when packed tightly. Such tyres see difficult time when being mounted on rims. This is a clear indication of smuggled tyres.
Some tyre sellers re pack the used tyres. You will notice that while unwrapping your tyre they don't cut that packing from inner side to get the trye our easily, rather they go the long tedious route to unwrap fold by fold saving the packing for next tyre. Also this packing do not match or not like the original packing in terms of color and pakibg material. Any user buying new just see that tyre is coming out od some packing he usually accepts where as actually he is getting a used or smuggled tyre.
All above are shady practices, avoid them as they by pass the legal import channel. They tend to be cheap but at the cost of tax theft.
Buy from proper importer or by its authorized dealer, yes such business are not prominent in market and we never get to know proper importer.
I have found that big stores like Metro are selling tyres and their products are guranteed as they source from Importer, like Shaikh Brothers etc. They will also stand by their warranty as all is documented in their invoice. They have wide collection as well.
Though I have dropped the idea of changing the tyre for now, but sharing what I learnt from the market research.
