Changing rim colour from TeamEditor will change the colour to the whole rim of course. As I said, I am pretty confident I saw one like that in a screenshot. I wonder whether it was edited.
Yeah, Fongu's right. I'm working with Alesi_fan and Tis at a full pack of tyres for 1991/1997 seasons. There will be a lot of different textures for rims and possibility to choose from 3d and non-3d rims. They'll be released ASAP, as we're working on some fibug-fixes now and we'll be doing the pack in a couple of days (hopefully)
