Manufactured by Bridgestone, this replacement tube helps provide reliable air retention and a secure fit inside the tire casing when installed according to the tire and vehicle manufacturer’s recommendations. Its standard construction makes it a practical choice for replacing a worn, damaged, or aging inner tube.\u003cbr\u003eThe tube is equipped with a PV78 valve stem for convenient inflation and pressure checks with compatible equipment. Proper valve stem alignment and careful installation are important for preventing pinching, twisting, or unnecessary stress during mounting. Before installation, inspect the tire, rim, and rim strip for damage or debris, and confirm that the tube size and valve configuration match the application.\u003cbr\u003eThis Bridgestone Standard tube is identified by manufacturer and vendor part number 543578. It is intended for use with a compatible 170\/80-15 tire and should be selected based on the vehicle manufacturer’s fitment requirements. Maintaining the recommended tire pressure and inspecting the tube and tire regularly can support consistent performance, handling, and service life. Confirm fitment before purchase, as tire and tube compatibility may vary by motorcycle, wheel design, and application.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrand: Bridgestone\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTire size: 170\/80-15\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTire model: Standard\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eValve stem: PV78 configuration\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eManufacturer and vendor part number: 543578\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication: Replacement inner tube for compatible motorcycle tire assemblies\u003c\/li\u003e\u003c\/ul\u003e","brand":"BRIDGESTONE","offers":[{"title":"Default Title","offer_id":49388195021035,"sku":"874-1916","price":43.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/7e15-68813371ea597_c761dc76-0a8b-4db2-8332-284c24cc5bbe.png?v=1789023473","url":"https:\/\/ctracingservices.com\/products\/bridgestone-standard-inner-tube-170-80-15-with-pv78-valve-stem-part-number-543578","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
