Nah, but your tires might be losing their grip. If they were mounted 2 years ago they could be a bit older. Check the DOT date on the sidewall. You will see something like this: DOT 1511. The first two numbers are the week of the year the tires were manufactured. The second two numbers are the year. So 15th week of 2011 in the example.2 year old pilot powers. You think I was just shredding some rubber?
