Cad for 8'' pneumatic tires

[ZoomZoom]

Does anyone know where to find any cad files for 8" pneumatic tires? I've tried vex pro and andymark.

AndyMark has CAD files on their website. Make sure to click on the "Downloads" tab on the product page. It's a STP file which you can import into just about any CAD program. Here's the direct link: http://files.andymark.com/PneumaticWheel_am-0970.STEP
