Bridgestone Tire Marking/Mounting?
I just got a pair of BT021 Bridgestones The tires have markings (yellow dots and small blue stripes) reminiscent of euro tire markings for balancing the tire/wheel. Do these markings indicate the heaviest part of the tire, or the lightest part of the tire?
Should the marks be opposite the fill valve or next to the valve?

The yellow dots go where the valve stem is. Thats the general rule of almost all tires, but a lot of manufacturers are doing away with the markings altogether.

The YELLOW dot indicates the light balance point on a tyre and aligns with the valve stem which is typically the heavy spot on the rim. If you have a RED dot then that takes priority and aligns with either a dimple or white paint mark found inside the rim. Different brands mark their tyres differently but this is how Bridgestone does it. Pirelli are completely different. Have a look at the blurb below. It is for car tyres but the motorcycle ones by Bridgestone are marked the same. A little searching on the web will verify this for you. Always verify the manufactures marking criteria. Simply lining up a dot the same on all brands is wrongheaded.
