Road encounters

So just put these tyre on my car today. Mine are 195/65R15. So far there is a great difference from my previous one which were michelin ones in terms on smooth steering. Also i felt that the car is a bit more agile on the road. So great beginning I guess. As per advice by my tyre specialist, I shall make the first wheel alignment, balancing etc... after 500km. Following what at each car servicing i shall make a rotation of all four tyre. By doing so he reckon that I should be able to reach 50,000km. Personally thats seems a lots for these cheap tyre BUT if it does then I will be one happy customer. In terms of grips and how it feel on wet road I shall revert back soon.
