The Front Tire of a Sunny's Electric Bike

I was wrenching in the garage last night on a sunny's electric bike, which a the backtire was just dust. I don't know how got so worn down, but there was nothing itit just looked like a tennis shoe with no soul on it,. Everything goske down to the belts. We're in a tire shortage. Can you get a new one? The front tire was in decent shape, cause i'm guessing with the electric bikes, the rear tire takes more of a beating than the front tire. And maybe it's that way with all bikes, but i didn't notice here woue serious disparity and wear between front and rear. Just the pedal bikes
