Levitas was designed around the unique characteristics of 45NRTH fat bike tires. The internal widths are tailored for each diameter to create a broad, well-supported tire profile that maximizes flotation, traction, and control for the most demanding winter conditions. A narrower spoke bed reduces weight where possible while reinforced rim walls provide strength and impact resistence.-32-hole drill pattern for strong wheel builds-Optimized relationship between tire volume and rim width for consistent contact patch and tire profile-Fits 4-5" wide tires-Recommended single layer of 30mm rim tape. Recommended valve length 65mm (or longer)-Tested to ASTM Category 3, suggested weight limit of 300 lbs
