I like the stumpy look. Wheels are cool but I'm not sure such lo-profile tyres are suited to off-roading. :)
Create a brush, assign it the texture and then PaintSurface, should do it.
And while we're about it does anyone know how to change only one texture if your model has more than one? ie, I've got 2 surfaces and want to entitytexture model,texture,"material name"?
