Hi everyone.

I'm trying to make tron Bike. but I'm facing problem with modeling Tyre tread ,
I know it works with bump-map. but If I do it with modeling than it looks better with shadow and reflection

As you see in image reference of Tyre I Need to model this line tread, I'm trying to do it with Boolean in both
Nurbs and Polygons. but seem it doesn't work. I can not get it smooth, the Tyre should be close I think.

but anyway if you better way please say something.

regards
