If you want to retain 14" rim size, then you can choose out of 175/65 R14 size or 185/60 R14. In case you want to move up to 15" rims then go for 185/55 R15.
If you want tyres that offer decent performance but have longer tread life, then MRF ZV2K would be a good option. The downside is that these tyres are a bit noisy, especially at high speeds.
In case you want something better, then Yokohama Earth-1 would be a very good option. Not only are these tyres reasonably priced, but they also offer great traction, comfort and handling. Even the tread life is quite good.
However, if you want something top of the line, then go for Michelin Energy XM2 or Bridgestone Turanza AR20.
Both these tyres offer superior traction, excellent handling and a very comfortable ride quality. While Bridgestone is more durable on rough roads, Michelin tyres offer better ride comfort and enhanced tyre life.
