I have these super ultra-cheap bike tires that have the following label on them;
700x250 , (25-622) , 28x1-5/8x1

I can't find this size anywhere. They were HELL to get on my rims. My rims don't have a size, but I'm guessing they are 700c. They are labelled Aofeng 8081TS

I might just buckle and buy new rims, tubes, and tires - but I'd rather not. My tubes are flat and I need new ones. What size should I get for this odd tire size?
