I bought 4 Master Craft Grand Touring tires size 235/65R/16. We put them on a Honda Odyssey. All was good they where 80000 mile tires one started vibrating it had about 26000 Miles on it. I took it back to the dealer where I bought them and they said the problem was the tire. We balanced the tire 4 times and nothing helped They said they thought it was out of round or starting to separate. They put on a new tire and said they would send the bad one in for adjustment. The dealer measured the tread depth in several places and said it averaged 7/32 tread still on the tire. They sent the tire to the company for the amount of the adjustment and the company said they measured the tire depth and found only 2/32 of tread left. I have three more of these tires that where put on the carat the same time and they all show an average of 6/32 to 7/32 of tread still on the tire. I feel this is a way for the tire company to rip of the consumer and keep from honoring there warranties.
