You can see our old site and existing logo at http://tokaisolidtire.com/ to get an idea of the company.
Please note that the logo *must contain* the words "Solid Tire." TOKAI cannot appear independently of the words "Solid Tire."
Capitalization and layout of the words is up to you as a designer.
The final logo needs to be something that works on a web site, on the side of a tire, on a polo shirt, on a plastic cup, etc, which means no fine details and keep complexity at a minimum.
What we're looking to do is freshen our design. We make solid tires, this isn't a sexy industry, but there's room for a professional, understated logo that communicates the strong, serious nature of our product while also carefully connoting the fact that we are a modern company that uses online technology to communicate directly with the people who use our tires.
In other words, it's industrial, but not old world or retro and not futuristic - something in between.
