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 resistance.32-hole drill pattern for strong wheel buildsOptimized relationship between tire volume and rim width for consistent contact patch and tire profileFits 4-5" wide tiresRecommended single layer of 30mm rim tape. Recommended valve length 65mm (or longer)Tested to ASTM Category 3 suggested weight limit of 300 lbsMax inflation 30 psi
