There's a lot of difference between conservative nd very conservative!
Your combination is 3 sizes larger than recommended. I'd have qualms about going 2 sizes over, and wouldn't consider 3, unless the tire was very undersize for its rating. Some are more undersize than others, BTW.
I wouldn't try it unless I had other wheels I could use the tire on if it didn't work.
I've never used Nokian, so I don't know where they fall in the undersize arena.
