Look for markings such as \"20 x 4.0\" or \"20 x 4.9\". Additionally, confirm that your rim's valve hole is compatible with a Schrader valve and that the valve length of 32mm is appropriate for your rim depth.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and Safety Guidance\u003c\/h3\u003e\n\u003cp\u003eWhen installing the inner tube, ensure the tire is fully deflated and carefully remove it from the rim. Partially inflate the new inner tube to give it shape before inserting it into the tire casing. This helps prevent pinching the tube between the tire bead and the rim during installation. Once the tire is seated on the rim, inflate it gradually, checking that the tire bead is evenly seated around the entire rim on both sides. Always refer to your tire's sidewall for recommended inflation pressure ranges and do not exceed the maximum pressure. After installation, perform a visual check for any bulges or uneven seating before riding.\u003c\/p\u003e","brand":"ULIP","offers":[{"title":"Default Title","offer_id":64137540698489,"sku":"ULP2842.00","price":19.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0902\/7076\/1337\/files\/chaoyang-inner-tube-20x4-0-4-9-for-engwe-engine-pro-3-0-boost-electric-bicycle-01.webp?v=1785602470","url":"https:\/\/www.evolt.eu\/cs\/products\/inner-tube-chaoyang-20x4-0-4-9-for-electric-bike-engwe-ep-2-boost","provider":"eVolt.eu","version":"1.0","type":"link"}
