Store Reviews

Deneen D

As always, I was treated with dignity and respect and like I was an old friend. While the news of the repairs needed and the cost was not great news, Marvin explained why the repairs are needed the possible problems I could have if I don't do them. Dan was also very accommodating and helpful with ordering a part for my other vehicle. After being treated very poorly when trying to have maintenance done at dealerships, I am so thankful that Sullivan Tire is there for me and my two vehicles! 12/15/2017

I cannot say enough for Dan and the guys at the Dover Sullivan Tire. I brought my car in yesterday because I'd had to jump start the battery and was concerned that it might happen again. They took the car in right away and checked it out, finding nothing wrong with the battery. They took about a half hour, checking one possibility after another, finally finding that the rear door wasn't closed tight, and since I hadn't driven the car for 2 days, the interior light must've drained the battery. They charged me nothing for this visit. Thank you so much! I can now drive around without the fear of being stranded with a dead battery! That's why I've been coming back for the last 12 years or more and will continue to recommend Sullivan Tire! 12/5/2017
