I have just done about 200kms on the new set of tires. I'm waiting till i complete atleast 1000km before I can push the car little hard to see how good the tire grips.
Another thing I noticed after the tire change is that the lugging capacity of the car has reduced. The car sometimes makes a fuss at city speeds when trying to accelerate at 2nd or 3rd especially after crossing a speed hump. The engine feels like it is working harder to pickup speeds at very low revs (1000-1200 rpm)
Hope this helps.
Will give a review once I have completed the running in of the tire.
