RCG-4 is the choice for the muddy days and the roughest of courses.

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\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eImportant: Never install tires with a tire lever.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSPECS:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e45, 50, 55mm options\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e545g in 45mm, 620g in 50mm, 650g in 55mm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e120 TPI\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSealSkin Bead-to-Bead Protection\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFastest Pulsar compound\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWidth as measured on a 25mm rim after 24 hours\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDesigned for mud and extreme conditions\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAggressive knob spacing for mud shedding and increased grip\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRCG-4 Architecture\u003c\/p\u003e\n\u003cdiv class=\"rte-setting text-spacing\"\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eAn aggressive, wide-spaced knob profile that uses fewer but significantly larger lugs than the RCG-3.
