If you don't drive much, then spending a little more on a set of Falken Sincera will give you better grip and less road noise. The difference will be noticeable instantly compared to the MRF at the cost of a shorter life.
Go for Michelin Energy XM2 or Bridgestone Turanza AR20 tyres for your Santro. Turanza would be a better option if your usage will be over rough or unpaved roads as they are more durable than Michelin.
I use a Hyundai Santro Xing (2012 model). The car is mainly driven on highways with not very good road-surfaces. Recently, I noticed the front tyres on my car with uneven tyre wear on one-side. I took the car to the repair shop where I was told to replace the tyres because they are worn out due to improper wheel alignment. I wanted to know if it is really necessary to replace the tyres?
A car that is being driven with misaligned wheels tends to ‘eat’ the rubber and causes uneven tyre wear. Driving a tyre with an uneven wear pattern will greatly reduce steering response- the car will tend to ‘pull away’ which will eventually be of great concern to you as a driver. It is advised that you replace the tyres asap (stick with the same tyre size and rating as before); get the wheel-alignment done and also have front suspension components such as tie rods and ball joints etc., checked
