However, if tyre tread life is your priority and you can compromise a bit on grip and ride comfort, then go for Apollo Amazer 4G Life tyres. Apollo claims that these tyres can run good up to 1 lakh kms.

I am having Tata Zest XMA 1.3 90PS Quadrajet Diesel car. And here is a challenge, Today I encountered one of my front tyre went flat due to puncture in the side thread area, and the local puncture guy told me this can't be fixed and I have to change the whole tyre. For time being I have replace it with my stepney which is a tube tyre with stell rim. Rest all my four tyres (including the one got flat) are alloy wheels. Mine is OEM Bridgestone 185/60 R15 84T B250. Should I replace my flat one with the same as the other one in the front ?
Seems like the puncture is in the sidewall and apparently any damage to sidewall is irrepairable and calls for a replacement. However, if the puncture isn't very major and if you do not want to replace the tyre immediately then you can go for a Mushroom-Puncture repair. But keep in mind that this will offer only a short term respite and soon you would have to replace the tyre anyway.
Since only one is damaged, it is best that you replace it with Bridgestone B250 only, in the same specs and size as the stock one.
