I have bran new tires. I only have 30 miles on them but I noticed something that seems odd to me. All the little rubber "whiskers" that are all over new tires are wearing off unevenly. With in the 1st 30 miles all the "whiskers" on the out side edge tothe center of the tread are gone but all the "wiskers" on the inside tread to the center are still there but only starting to wear down. All 4 tires are like this. Is this normal or is smothing not right? It seems that the outside is wearing much faster then the inside of the tire. Thank you!
