Anxiety Disorder Due to Medical Condition. Some diseases and Illnesses cause anxiety, including symptoms that directly mimic anxiety disorders. For example, thyroid conditions can cause sudden and extreme anxiety. Lyme disease can also cause panic attacks and anxiety.
SL: Standard Load; tire for normal usage and loads; XL: eXtra Load; a tire that allows a higher inflation pressure than a Standard Load tire, which increases the tire's maximum load; RF: Reinforcedâfor Euro-metric tires, the term 'reinforced' means the same thing as 'Extra Load' RFT: Run-Flat Tire; Tires designed for vehicles without spare tires.
The definition of an âAmerican-made tireâ is fluid, however, which makes it easier for dealers to sell it as such. Let me explain. There are only two major American-owned tire manufacturers: Goodyear Tire & Rubber Co. and Cooper Tire & Rubber Co. Each of them has multiple manufacturing plants in the U.S. So any tire with the name Goodyear or Cooper on it can be sold as American-made.
