Getting the tires over the rim is sometimes a challenge, but getting it seated evenly is not. Deflate, Adjust, Reinflate. Simple, and nothing needs to be applied to the rims.
Just means you haven't dealt with enough tires. Not everything works just perfect and especially with tires that stretch after a bit of riding the initial seating can be an issue. Sometimes the solution in just inflate till it works but with older steel rims and modern hookless rims there can be a challenge since the pressure can't go high enough to force the seat without blowing off completely.

Just had to deal with this last week seating some vittoria cross tires on new wheels. The tires were used a couple times last year and never had any trouble installing on old hooked rims. This year on new hookless rims they were a bit of an issue getting them to seat. Doesn't help you can't just pump to 100 and wait for the pop. This is also why park makes a bead seating tube. Personally not a fan of hookless rims but the price was right and the bike never runs less than 30c so the low pressure requirement isn't an issue.
