Check your tire PSI's for sure that would be the first thing to check, that can cause a pull. Then if that dosen't fix it you could swap your two front tires around make sure a tire isn't causing the pull, those are the two things you can do. If that dosent fix it take it to the pros, and have the alignment checked, you could purchase a lifetime alignment from a lot of places they usually cost like twice or three times the price of one alignment, but it is worth it if you are going to keep the car for a long period of time. Should be checked twice a year, if you want to get the best wear from your tires.
