Chelsea, Who did you talk to? I do not recall talking to you? what car do you have? Was the estimate given from my Lincoln Shop? We try to match any written estimates that we have from other shops. As for the tire I really do not think we would switch any tires we are not a tire shop and do not even have tires to switch with. If you would like call My son Jayson (248-545-7465) and see if we can straighten this out. Thank you. and i hope you have a great weekend.
