Previously using Century Marathoner NS60 on mine and it lasted over 2 years but it always required jump start whenever I left the car idle for more than 4/5 days. After that change to Delkor, which seemed a bit better as at least when a few months old can still start after the same idle period, but maybe after 9 mths use then it cannot be left idle like that anymore so become similar to the Marathoner. I've exchanged that under warranty on the 11th mth when it dropped again, then put the new replacement in my wife's car. Then now I'm on Century Ultramax but cannot really comment much yet since it's still just a few months old. So far just like the Delkor seems better than the Marathoner but not sure later.

. I'm a proud owner of a Proton Inspira 2.0E. 2012 model, purchased & collected 30th July 2013 which makes my car is only 6months old. All 4 tyres are Continental which came with the car.
