 Hyundai is making defective vehicles that destroy tires.  They will not acknowledge the defect.  A few customers have been lucky and had their rear axles replaced at no cost, but most customers will just be told nothing is wrong and it must be the way they are driving or some other nonsense.  I have 40k miles and have gone through 3 sets of tires on the rear.  The set I have on now cupped badly within 5k miles and makes the car vibrate and very noisy.  Both the dealership and the company will not acknowledge or fix the problem.  
 Do your research before you buy this car.  You will see there are many people having problems with rear tire wear/ handling/ noise/ rear axle problems.
