CJ, let me be the PITA and point out that whoever installed the tires didn't do a PERFECT job... I'm a perfectionist, so forgive me: the yellow dot (or the red one, not sure which one) is supposed to be aligned with the stem valve to minimize weight addition on the tire when balancing... If you look on your tires they are mis-aligned...
If you take a look here
toward the end you'll see what I'm talking about...
I love the hard top!!!
Well it's a good observation and one that was taken into account. As you note the general rule is to align the yellow dot to the valve stem, however if there is a red too it is aligned to the weigh mark on the rim, thus putting the heavy and light spot of each together. On the inside of the rims we found a punched mark That is what my fitters have worked to. Looking at your reference article it does say the same if you read futher down:
What if both dots are present?
Generally speaking, if you get a tyre with both a red and a yellow dot on it, it should be mounted according to the red dot - ie. the uniformity mark should line up with the dimple on the wheel rim, and the yellow mark should be ignored.
OK so I have refurbished the rims too, stripped lacquer and removed the centres. They too have multiple layers of powder coat and paint, etc. so any original weighting would have been lost, but we tried. As a final point the tyre fitter I use removes and remounts any tyres that the system shows to be out of balance and see if he can get a better 'natural' balance. (Although local he is actually the specilaist tyre fitter for all exotic makes for a 50 mile radius and was at the time about to fit a set of Ferarri tyres and had a set of 22" Brabus 4x4 to do - no doubt a local drug Barons car..lol)
I too am a perfectionist
Thanks for the comment on the hardtop. I love it too and very practical given the current weather
