so my bf just got new tires on his car but the front right one gets flat so fast. he thought he ran over something like a nail so he put the donut tire on it and now that is also flat. we are kind of broke right now and tired of spending money on tires.. but how can we figure out what the issue is without spending thousands of dollars?
