MRF ZLX would be a good tyre for your Zen Estilo VXI. It offers a well-cushioned ride quality along with good grip over wet and dry surfaces.
If you want a tyre that delivers superb tread life then go for CEAT MIlaze X3 tyre. CEAT claims that this tyre has a tread life of around 1 lakh kms. It fares good on grip and comfort levels too.
However, if you are looking at something top og the line in terms of grip, comfort and handling then go for Bridgestone Turanza ER60. It is one of the best tyres out there with respect to comfort, safety and tread life, but is a bit on the expensive side.
I have a 2011 maruti Suzuki zen estilo which has run 37k kms
And at 33k kms I changed my tyres to bridgestone s322 155/65 r13
And now I want to know how can I make them live longer
