Bike tire size advice needed

Ok so I bought a mountain bike second hand. I noticed the tyres are almost impossible to get on and off and I’m thinking they’re maybe too small.
the rear tire is 559 -17 and the front is 599 -19.
What tires do I need to purchase?
 
Are there any size markings on the rims?

That’s the rim sizes I posted, I didn’t know how to go back and edit it. The actual tyres are 26x1.95
