I've rotated mine every 5K miles, it's about time again and they look the same (wear wise) front and rear. There is no vibrations or unusual wear pattern. When should you have your tires rebalanced versus just rotated? Think I should go to 7K mile rotation/balance, since based on observation and ride they don't look like they need it at 5K miles? I have the Michelin SUV Cross Terrains on mine and I want to get the most wear possible out of them. The reason I'm asking is that I've found over the years that some vehicles are easy on tires and don't need the frequent rotations, wondering if the new 4runner is one of them?
