{"product_id":"protocol-rcg-4","title":"Protocol RCG-4","description":"\u003cp\u003eThe ultimate off-grid tire for sloppy mud, sand, and loose rock. The Protocol RCG-4 utilizes aggressive, widely spaced lugs that shed sticky loam and mud. Designed to bridge the gap between adventurous gravel racing and mixed trail terrain, this tire thrives in shifting, unpredictable conditions like mud, sand, and steep, loose rock. Wrapped in full bead-to-bead puncture protection, it gives you the confidence to tackle everything from singletrack, OHV roads and off-camber loose rock without fear of sidewall tears. The RCG-4 features an aggressive, wide-spaced knob profile utilizing fewer, but significantly larger, lugs than Silca's RCG-3 model. This intentional spacing prevents dirt and sticky loam from packing together and caking the tire. In sloppy conditions where other tires might clog and lose traction, the RCG-4 actively flings mud away, ensuring reliable bite and uninterrupted momentum. \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePulsar Compound: A high performance rubber and silica race compound engineered to hold rolling efficiency, grip, and durability in balance rather than trading one away for another\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRace Casing: A race casing architecture developed around modern tire pressures, so the tire keeps its shape and its ride quality at the pressures wide rims actually run\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCarbonBead BeadLock: Carbon fiber bead technology that keeps the tire dimensionally stable across its whole life, so the width you measure at installation is the width you keep\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSealSkin: Enhanced puncture protection for terrain that asks more of the casing, adding durability where the ground is rough enough to make it part of being fast\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTubeless Ready: Engineered for modern tubeless systems from the bead out, so sealant, valves, and lower pressures all work the way they were meant to\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e120 TPI\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSealSkin Bead-to-Bead Protection\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFastest Pulsar compound\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWidth as measured on a 25mm rim after 24 hours\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesigned for mud and extreme conditions\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAggressive knob spacing for mud shedding and increased grip\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e545g in 45mm, 620g in 50mm, 650g in 55mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Silca","offers":[{"title":"Black \/ 700c x 45","offer_id":41256008941640,"sku":"2050020005958","price":99.0,"currency_code":"USD","in_stock":false},{"title":"Black \/ 700c x 50","offer_id":41256008974408,"sku":"2050020005965","price":99.0,"currency_code":"USD","in_stock":false},{"title":"Black \/ 700c x 55","offer_id":41256009007176,"sku":"2050020005972","price":99.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0751\/7203\/files\/100400246-BLK-1.png?v=1787763813","url":"https:\/\/www.sportsbasement.com\/products\/protocol-rcg-4","provider":"Sports Basement","version":"1.0","type":"link"}
