Nico Rosberg admits it could be a bit of a struggle at the start of Sunday's Indian GP after he opted to qualify on the soft Pirellis.
Throughout this weekend's sessions at the Buddh International circuit, the Option tyre has taken a battering.
Not only does it suffered graining and blistering after just a few laps but the drop-off in lap time can be quite severe.
But despite this, Rosberg was one of six drivers in the top eight who opted to use that tyre in qualifying.
The German posted the second fastest time, 0.752s behind Red Bull's Sebastian Vettel, to return to the front row of the grid.
"To be honest I'm completely on a knife's edge, really pushing to the limit, trying to extra that little more out of the car," said the Mercedes driver.
"Been trying different things, new ways, new set-ups and now it worked so I'm very pleased with that.
"Qualifying second is better than I hoped for - because of Mark being on another strategy.
"So for the moment it is looking okay but the race will be tough because it's very different circumstances here.
"The Option tyre will struggle a bit at the beginning of the race tomorrow, the Prime will be okay but we'll see."
