I can't find anything other than 26x1.75 and the manufacturer on the rim. Though I see 50-559 on my current tire. Does this helps? Thanks

These are ETRTO (European Tire and Rim Technical Organization) measurements, and are above all else, the most important numbers associated with marrying up rims and tires.
559 is the ETRTO number for what is commonly referred to as a 26" rim/tire.
