For one it is very hard to get a flat with a studded tire. Second, if you struggle this is because you are presumably not very effective working with tires. There is nothing to be ashamed - we all learn. This video
How to get tire off without tools
shows how to get a tire off without any tools. There may be other similar instruction materials around. I would start with regular tires for the sake of training. From time to time I do it with studded tires for practice. In everyday life I am usually lazy and use the levers for speed, but just a little. You may say that rims vary and I presumably have the easy ones. OK, I do it with 16" tires too. On a small wheel you have far less margin than on large. Take your time, be patient, hands alone are actually sufficient.
That's warm weather and a non-studded tire.
Personally I would not use a tire/rim combination I could not easily repair at the side of the road. I had that happen to my in 1991 and I broke a VAR tire lever and another tire lever trying to get a tight tire OFF the rim. Since then if the tire/rim is really hard to mount, I use either a different tire or a different wheel. I do not want to be stuck out in the boonies or anywhere for that matter simply because I can't get a tire off the rim - especially in winter.
Edit. If I was buying a studded tire I'd take the CLEANED wheel with me to see how easy/hard the tire was to mount.
