I changed my tyres to Michelin P3ST last Friday since I was travelling to Kollimalai, which is a small hill station near salem (will write a travelogue about it soon). I did not want to risk taking the car with had side wall punctures (though fixed) in both its rear tyres. Total cost, including wheel balancing and alignment and the exchange for the old tyres came to 24K. I went in for the stock profile, 195/60 R15. I must say the tyres are silent and I can feel the difference in the ride. Though on the higher side of the cost, the tyres are really good. Have already done around 800 KMS in the new tyre, highways, ghat roads and bad roads and I should say I am happy with the tyres.
