Ordered a set of Bridgestone tires from Bill a few weeks ago. Tires arrived promptly and had them installed today at a local family owned tire shop (not chain) which has been in business for decades. Had the tires mounted on the standard wheels so I can preserve the option wheels that came with the car. Plus I like the standard wheels more. After the tires were mounted I noticed the little yellow dots on the tires didn't line up with the valve or the with black markers on the wheels. Asked the tech mounting the tires if he knew the significance of the dots on the tires and wheels, he had no idea what they represent or what to do with them. His senior supervisor said they are there just to let the factory know "they're done". The store owner knew vaguely what the markers represent but said he never paid any attention to them for as long as he's been in business. Question to the experts here, what do you think? Shouldn't these markers be used in mounting and balancing the tires or can they be totally ignored?
