This model uses a TR-4 center\/side metal valve configuration and is identified by Michelin manufacturer part number 65843 and vendor part number 65843. It is intended for applications requiring an 18-inch tube with a durable metal valve and dependable air retention.\u003c\/p\u003e\u003cp\u003eDesigned with the splice positioned opposite the valve, the Michelin 65843 inner tube promotes a more balanced tube assembly inside the tire. Its overlap splice is stronger than the butt splice commonly used in many other inner tubes, supporting durability under normal riding and operating conditions. This construction makes it a practical replacement for compatible powersports, utility, agricultural, or industrial tire applications.\u003c\/p\u003e\u003cp\u003eBefore installation, confirm that the tire and rim require an 18-inch standard tube and that the TR-4 center\/side metal valve matches the original valve position and configuration. Michelin Airstop tubes are selected by users seeking high-quality replacement components for compatible fitments. Always inspect the tire, rim, valve opening, and tube size before mounting, and follow the tire manufacturer’s installation recommendations.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSize: 18-inch standard inner tube\u003c\/li\u003e\n\u003cli\u003eModel: Airstop standard tube\u003c\/li\u003e\n\u003cli\u003eValve type: TR-4 center\/side metal valve\u003c\/li\u003e\n\u003cli\u003eConstruction: Overlap splice for increased strength compared with a conventional butt splice\u003c\/li\u003e\n\u003cli\u003eSplice placement: Positioned opposite the valve for improved tube balance\u003c\/li\u003e\n\u003cli\u003eBrand: Michelin\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 65843\u003c\/li\u003e\n\u003cli\u003eVendor part number: 65843\u003c\/li\u003e\n\u003cli\u003eFitment: Compatible with tires and rims specified for an 18-inch standard tube and TR-4 center\/side metal valve\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICHELIN","offers":[{"title":"Default Title","offer_id":67544818974955,"sku":"03500430","price":42.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/112169.png?v=1790646439","url":"https:\/\/ctracingservices.com\/products\/michelin-18-inch-standard-inner-tube-tr-4-center-side-metal-valve-part-65843","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
