Excelsior Stahl Sport Radial | 550R18
Excelsior Tires | Excelsior Tire The world's first line of radial tires offered in sizes and styles to replace popular bias ply profiles. The Stahl Sport Radial from Excelsior Tire is inspired by vintage competition tires and is equally at home on vintage racers as it is on hot rods. This tire has also become very popular on deuce coupes, Model A hot rods and roadsters. Excelsior Tires are made in the USA and DOT/ECE (European Community) approved. Please note that dimensions listed tread width, section width and overall diameter are non-scientific and based on an inflated tire, mounted on a wheel. Dimensions may vary due to rim width and inflation pressure.
