Vintage Goodyear Tires G167 Unisteel Blue Glass Tire Ashtray

I am selling a Vintage Goodyear Tires G167 Unisteel Blue Glass Tire Ashtray. It is pre-owned and in good condition. It is a rubber tire with a glass insert in the center. It measures about 6 1/2" across. The tire has Goodyear and G167 Unisteel on it. The ashtray has a Goodyear printed on it with a blue background. The blue paint has a scratch in it which you can see in the pictures.
