...the yellow mark or red should be at the valve stem there. OR try remove your tire and see the back of the rim where the red mark is...is the back of the rim got a dimple there.

The yellow dot is there for GUIDANCE, usually it has to be placed at the valve. However, certain condition when the rim is bent/tyre balancing is too crappy, the guide has to be placed at the opposite side of the vale to obtain optimum balancing. If still balancing out, the balancing sifu will have to manually adjust the tyre positioning without refering to the guide, until able to find the most balance weight on the tyre against the rim.
nestum,

Yep it was me. This is an excerpt from the Yokohama website on the red and yellow dots.

Uniformity Method (Red dot)
When performing uniformity match-mounting, the red mark on the tire, indicating the point of maximum radial force variation, should be aligned with the wheel assembly's point of minimum radial run-out, which is generally indicated by a colored dot or a notch somewhere on the wheel assembly (consult manufacturer for details). Radial force variation is the fluctuation in the force that appears in the rotating axis of a tire when a specific load is applied and the tire rotated at a specific speed. It is necessary to minimize radial force variation to ensure trouble-free installation and operation. Not all wheel assemblies indicate the point of minimum radial run-out, rendering uniformity match-mounting sometimes impossible. If the point of minimum radial run-out is not indicated on a wheel assembly, the weight method of match-mounting should be used instead.
Weight Method (Yellow dot)
When performing weight match-mounting, the yellow mark on the tire, indicating the point of lightest weight, should be aligned with the valve stem on the wheel assembly, which represents the heaviest weight point of the wheel assembly. After match-mounting by either of the above methods, the tire/wheel assembly can be balanced.

Hi guys, what's the max rim size of saga can go? Wanna change... Any intro?
The largest I know is 17"
