Some years ago I asked a co-worker who used to live in Sumter "Are there ANY auto-mechanics in Sumter that I can trust?!?".
My co-worker recommended Frasier Tire on East Liberty St in Sumter. He used to work there when he was in college and told me to go see Patrick.
Now I would have never thought to go to a Tire store for all of my automotive needs but now days I wouldn't even dream of going anywhere else. My husband and I have a variety of vehicles, from brand new to way past ancient. Patrick, Randy, David and the rest of the guys take care of us like we are family. Frasier Tire gets my highest recommendation.
