Ideal for riders running fat tires on freestyle bikes, cruiser setups, dirt jumpers, or kids' bikes with wider tire profiles. The multiple size options cover nearly all BMX wheel configurations: 20\" for standard BMX and cruisers, 18\" for mini BMX, 16\" and 14\" for intermediate kids' bikes, and 12\" for balance bikes or toddler BMX bikes. When selecting tube size, match both the wheel diameter (12\", 14\", 16\", 18\", or 20\") and verify your tire width falls within the tube's recommended range. Always slightly inflate the tube before installation to give it shape, then deflate before mounting to prevent pinching between tire and rim.\u003c\/p\u003e","brand":"CULT CREW","offers":[{"title":"12\"","offer_id":45037459275955,"sku":"sku-43155698024702","price":4.99,"currency_code":"USD","in_stock":true},{"title":"14\"","offer_id":45037459308723,"sku":"sku-43155698057470","price":4.99,"currency_code":"USD","in_stock":true},{"title":"16\"","offer_id":45037459341491,"sku":"sku-43155698090238","price":4.99,"currency_code":"USD","in_stock":true},{"title":"18\"","offer_id":45037459374259,"sku":"sku-43155698123006","price":4.99,"currency_code":"USD","in_stock":false},{"title":"20\"","offer_id":45037459407027,"sku":"sku-43155698155774","price":6.99,"currency_code":"USD","in_stock":true},{"title":"26\"","offer_id":45037459439795,"sku":"sku-43155698188542","price":8.99,"currency_code":"USD","in_stock":false},{"title":"29\"","offer_id":45037459472563,"sku":"sku-43155698221310","price":8.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8737\/2979\/files\/rubbers.jpg?v=1759233134","url":"https:\/\/time2shinebmx.com\/products\/cult_cult-rubber","provider":"Time 2 Shine ","version":"1.0","type":"link"}
