I went in to ntb to purchase a set of tires finally someone waited on me.The tires were purchased after whatching the man balance the tires i went to the sales man and complained about the tires carrying to much wait he assured me it was fine. I new right thin it was going to be trouble. I worked at NTW years ago on Rossville Blvd. Chattanooga Tn. as I figured the truck vibrated pretty bad . I didnt have time off from work to return until it was time for the tires to be rotated.I explained to the salesman the situation Of course i was going to be charged for the balancing again.Ok asked the salesman if they turned the tires 180 degrees or 90 degrees to try and get the wait and make the tire roll smoother he had know idea what i was talking about so I explained He said o sure we do that and also I didnt want them putting a lot of wait on the tires with out turning them He agreed . I made a appointment . Showed up on time took almost 30 minutes to get the truck in the bay then the service guy didnt even know how to put the truck on the rack after 40 minutes he finally got it in the air started balancing the tires never checked the air pressure started adding wait right off the bat.I watched him do this to two of the tires. went to the sales man told him he said how do you know he did answer I was watching him had a few word finally told him if the where not going to do what we agreed on to putt the truck on the ground of course I didnt know what i was talking about. Then another salesman got involved he was dumber than the first one put thought he new every thing.So my truck got put on the ground and is worse than what it was. Never will I be back at NTB or any one in my family and I have a big family and a lot of friends .Take my advise go somewhere else the at least knows what they are doing NTB is nothing but a rip off.
