Hyundai ix35 Tyres

Will they last 50,000?? Having driven my Hyundai ix35 from brand new I am now heading into for 45,000 miles of mostly motorway driving and I'm still on the factory set of Hankooks. They been rotated and and there's a good bit left yet. For the record I don't drive like Miss Daisy! The car is not the quietest or the sportiest so difficult to rate them in terms of other performance but for wear alone they get 10 from me.
