Crafted with a structure that harmonizes perfectly with the car’s chassis, these tires provide excellent grip, consistent handling, and impressive directional stability, even though they remain vintage bias ply tires in design.\u003c\/p\u003e\n\u003cp data-sourcepos=\"5:1-5:659\"\u003eDuring the inter-war period, the PIRELLI STELLA BIANCA tire marked a significant advancement in tire design. It exhibited unique tread patterns and construction characteristics of that era. The tire incorporated distinct features such as a cord carcass fabric, low inflation pressure (for tires of the day), and a straight-side bead profile. These characteristics endowed the 550-18 PIRELLI STELLA BIANCA with excellent directional stability, even at high speeds. A defining aspect of the Stella Bianca was its tread pattern, defined by trapezoidal blocks securely linked by robust “bridges”, which effectively resisted tearing when driven at high velocities.\u003c\/p\u003e\n\u003cp data-sourcepos=\"7:1-7:209\"\u003eThe PIRELLI STELLA BIANCA also stood out as the only V-rated bias tire of its time, denoting its ability to achieve speeds up to 149 mph. Such performance standards were recognized by iconic automobile brands.\u003c\/p\u003e\n\u003cp data-sourcepos=\"9:1-9:48\"\u003e\u003cstrong\u003eKey Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-sourcepos=\"11:1-17:126\"\u003e\n\u003cli data-sourcepos=\"11:1-13:37\"\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 5.50-18\n\u003cul data-sourcepos=\"12:5-13:37\"\u003e\n\u003cli data-sourcepos=\"12:5-12:48\"\u003e\n\u003cstrong\u003e5.50:\u003c\/strong\u003e Nominal section width in inches.\u003c\/li\u003e\n\u003cli data-sourcepos=\"13:5-13:37\"\u003e\n\u003cstrong\u003e18:\u003c\/strong\u003e Rim diameter in inches.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli data-sourcepos=\"14:1-14:124\"\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Vintage bias ply, cord carcass fabric, low inflation pressure (for the era), straight-side bead profile.\u003c\/li\u003e\n\u003cli data-sourcepos=\"15:1-15:76\"\u003e\n\u003cstrong\u003eTread Pattern:\u003c\/strong\u003e Trapezoidal blocks securely linked by robust “bridges.”\u003c\/li\u003e\n\u003cli data-sourcepos=\"16:1-16:38\"\u003e\n\u003cstrong\u003eSpeed Rating:\u003c\/strong\u003e V (up to 149 mph).\u003c\/li\u003e\n\u003cli data-sourcepos=\"17:1-17:126\"\u003e\n\u003cstrong\u003eKey Features:\u003c\/strong\u003e Excellent grip, consistent handling, impressive directional stability, tread pattern resistant to tearing\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pirelli","offers":[{"title":"Default Title","offer_id":40855542890554,"sku":"SMC.000.146","price":613.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/4846\/2650\/files\/Porsche-Pirelli-Stella-Bianca-Tire-5-50-18-SMC-000.jpg?v=1747931797","url":"https:\/\/sierramadrecollection.com\/products\/porsche-pirelli-stella-bianca-tire-5-50-18-smc-000-146","provider":"Sierra Madre Collection","version":"1.0","type":"link"}
