This is the 20x3.0 replacement tyre for the Hitway BK6 electric fat bike. Tire size on a fat e-bike is not a cosmetic choice — the 20-inch rim diameter and 3.0-inch width together set the contact patch, the ride height, and the clearance to the frame and fender. Fitting the wrong size changes all three, and a tyre that is too wide will rub the chainstay or the mudguard before it ever rolls.

Tires are the highest-turnover consumable on any e-bike, and the BK6 is no exception. The wider casing carries more load than a standard bicycle tyre at the same inflation, which is exactly what a motor-driven fat bike needs — but it also means the tyre is worked harder and wears sooner than the equivalent tyre on a pedal-only bike.
