Bicycle trainer tyre - understanding the sizing The weather where I live is very bad sometimes. I was thinking of buying either a magnetic or fluid trainer or rollers. I read that the tyres wear out quickly on those and one should use specific tyres for indoor trainers and rollers.

I'm a little confused about the sizing. In a sticker on my rims, it says

ETRTO Rim size: 584 x 19C Inner Rim Width: 19C
ETRTO Recommend Tire Section Width: 28mm - 62mm


On my tyres there's the following

37-622 (700 x 37C - 28 x 1 5/8 x 1 3/8)


What do these mean?

The indoor trainer tyres I'm looking for have a few options:

26 x 1,1
700 x 23C
26 x 1,75
700 x 32C


Which one of these suits my rims?
You're on the right track buying a trainer-specific tire- trainers generate a decent amount of heat and eat tires. 

Your current tire is a 700c x 37, so out of the list, I'd go for the 700 x 32. The 26 options won't fit on the rim.
