$30 for a tire plug is very expensive. After I find out the about the cost, I did some research online to find out why it was so high. I discovered that a tire plug and patch was required in addition to removing the tire from the rim. That seemed to justify the additional expense. When I received my truck back I inquired about the job and discovered that only a plug was used and the tire was not removed from the rim. I feel as though I definitely did not get good value for my money. In the future I will get service at another dealer or at a specialty tire shop. Though I was gouged on this particular service job it came at the expense of my future business for both of my Chevy’s.
