Fit Check: Fits 8.5x2.0, 50/75-6.1 and 8 1/2 x2 solid scooter tires. These markings refer to the same tire size. Please check your original tire marking and wheel dimensions before ordering. Compatible with select Gotrax GXL V2/XR/APEX, Hiboy S2 and other scooters using this tire size
Size Warning: This is an 8.5-inch OUTER DIAMETER tire (ISO: 50/75-6.1) designed for a 6.1-inch nominal rim size. Actual rim diameter: 6.5–6.65 inches; rim groove width: 1.26–1.34 inches. Verify your wheel dimensions before purchasing
Tight Fit: Solid scooter tires are intentionally made slightly smaller than the rim for a secure fit. The tire stretches during installation to help reduce slipping after mounting. If the tire looks small when received, this is normal for this type of solid tire
Flat-Free: The airless, tubeless solid rubber design helps avoid flats, inner tube damage and repeated inflation. Grooved tread provides reliable road contact for everyday commuting on paved roads and city streets
Install Tips: Soak the tire in boiling water for 20-30 minutes to soften the rubber before installation. Solid tires require strong force to stretch onto the rim. Tire levers, clamps, two-person installation or a professional scooter/bike repair shop are recommended. Watch the installation video before starting
