Depends on the kind of grinding. The brakes may have been messed with, so you'll getting a constant grinding noise. If the noise is audible when you first turn the vehicle on and it not in motion, then you have other problems. If you only hear it while the vehicle is in motion, then you should take it back to the shop where you got your tires replaced.
Possibly the wheel bearing, if it makes a whiring noise when you accel. Or cv-axel, if it sounds like its grinding.
Brakes
Grinding noises, wandering steering, strange tire wear.
On Front Wheel Drives, when the CV Joint is going bad it will do this because the joint is not wearing out and when turned you get a clacking sound. I believe it is the CV joint opposite of the way you turn that is bad.
most grinding noises that come from turning is usually a cv axle that needs to be replaced. Can also be a bad wheel bearing. If you hear the grinding when turning to the right then the left front wheel bearing is bad.
Front wheel bearing needs immediate replacing.
Front grinding is when you and your partner's sexual organs are grinding together. It is more risky than back to front grinding because in front grinding the male's genitals tend to go inside the female's vagina. It is basically having real sex with clothes on.
Have your brakes checked, rust or wear on brakes can cause grinding when turning.
power steering
sqeaking/creaking noises front the front of the car will most likely come from the control arm bushings or sway bar bushings. Bushings are pieces of rubber (or polyurethane if you have a performance vehicle) that fit between the metal parts of the car (similar to a function of a rubber washer). When the rubber gets old and breaks down it tends to sqeak/creak. These noises can be louder with temperature and humidity changes in the weather. There ya go. Have fun replacing them.

You might hear loud squeaking noises. jack up the front end and try to wiggle the wheel. if it wiggles then it could be the bearing. You could be hearing a grinding noise also.
