Big tire

Modeled a tire today. I had not done this type of planar-to-circular pattern modeling for a while so i used more time than i would have preferred. modeled in 3dsmax rendered in mentalray. still playing around with physics based lighting, there are a lot of parameters to consider as apposed to just dropping a few omni lights to form a 3 point rig as iwe been doing before. rendering times are a bit higher too. this one took ca 30 min to render.
