there are a couple of things you can try
1 , If you need new tires , Try that , Cause you know you need them anyway
2 , If the noise is still there , It could be a Wheel Bearing if it a deep piched Growling noise that gets more pronouced taking turns.
3 , Breaks can give you noises , but it doesnt sound likely in this case.
Try 1 first.. then see if 2 applys if not move on to 3
