Almost every 1 or 2 sizes have a corresponding inner tube. This can stably support the outer tire, and the inner tube wall thickness can still be the expected thickness under the set tire pressure.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp data-mce-fragment=\"1\"\u003e \u003cstrong data-mce-fragment=\"1\"\u003eIn other words, if you use a 2.4\" outer tire with a traditional 1.75-2.125\" inner tube, this means that you have to expand the inner tube to a larger size to support the outer tire, which will sacrifice the thickness of the inner tube, making it easier to puncture the tire under external impact. If you find that you often have flat tires for no reason, you may want to check whether the size of your current inner tube is too different from that of the outer tire!\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\n \u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003e- 20\" x 2.2\" - 2.4\" for wide tires\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli data-mce-fragment=\"1\"\u003e \u003cstrong data-mce-fragment=\"1\"\u003eSchrader Valve\u003c\/strong\u003e\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003cstrong data-mce-fragment=\"1\"\u003e- Weight: 197g\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp data-mce-fragment=\"1\"\u003e \u003cstrong data-mce-fragment=\"1\"\u003e-Warranty\u003c\/strong\u003e \u003cstrong data-mce-fragment=\"1\"\u003e: If there is any damage not caused by external forces, such as poor air tightness (leakage) or defective air nozzle (leakage), please notify us within 7 days of installation and STASH will provide free replacement!\u003c\/strong\u003e \u003cstrong data-mce-fragment=\"1\"\u003e[Damage caused by impact (snake bite) or puncture is no longer covered by warranty]\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp data-mce-fragment=\"1\"\u003e \u003cstrong data-mce-fragment=\"1\"\u003e- MADE IN CHINA (Made in Taiwan by Goodman Industries China Factory)\u003c\/strong\u003e\u003c\/p\u003e","brand":"UNITED","offers":[{"title":"Default Title","offer_id":51864142381346,"sku":null,"price":150.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0818\/5069\/5970\/files\/united_innertube_new_720x_2b2a3b4c-a756-4796-9a03-11a7381b2f45.png?v=1782396543","url":"https:\/\/stashtaiwan.com\/en\/products\/united-20-x-2-1-2-4-bmx-tube","provider":"STASH BMX DISTRIBUTION","version":"1.0","type":"link"}
