My friend had two tires wear out too soon(2000 miles), at this time no adjustment for the new tires made and at this point not expected. Had to make an appointment for new tires. 11:00 AM. Got there at 10:30 AM. tires completed at 12-1:00PM.!!! What is the purpose of a time frame? I could have gone to an emergency room with a splinter and got out faster!!! Hoover Al. Costco stinks (at least the tire dept). Tire department personnel for the most part, lack of knowledge or rude! Next time Sams Club or retail tire store. Only 1 person from the install department seemed concerned, and of course is was flack!!! The manager was not there of course! So sad!!!
