Towards the end of that section, the car was very skittish, and i had to back off for a few minutes. Forgot all about it and speeded up back to 160 again on the same drive and everything was fine.
The wierd bit is, i took the car to 170 for a few seconds the day before that and it was rock solid. it seems to be the prolonged high speeds that the tyres dont like. short bursts are handled very well.
I routinely do 600 km runs at full throttle with my swift P on S Drives , full throttle thru-out ie mumbai-belgaum which have lovely roads.
Past 15000 km the s drives need to be replaced until then I had no issues at all .
