That was an excellent job of cleaning !
How did you do it ?

BTW : even though the first image is upside down, I found that if you open it, then right click and choose 'view image', it goes right side up !

A bit of trivia : if you examine the 3rd picture closely ( right click, view image ), you will see that 5 of the spokes have no indentions, these are directly opposite the valve core/TPMS position ( between the "Made in" and the "Poland" spokes ).
This extra tiny bit of weight is designed to offset the weight of the TPMS.
