i lightened up the tire texture a bit so you can see the tread (which was very difficult to figure out how to make)

and i rounded the tire a bit to make it look a bit more "inflated"



the tire texture right now is just a preset shader from highend3d but if anyone has a really realistic tire texture help me out, also, if anyone comes across a nice logo for potenza and bridgestone that i can use as sidewall lettering like in the first picture let me know as well
