Okay so you should check out Artifexian's Video on axial tilt.

But to sum it up, the higher the tilt the warmer your planet will be and have more extreme seaons.

It will also result in less snow, permanent ice, lower humidity and cloud cover.

Life like humans won't be able to survive on a tilt greater than 80 degrees. So to answer your question as close to 80 as your comfortable and it will still be plausible.

Final thing to note is that if you go above 53degrees your tempature zones reverse, so your polar regions will be at the equator and your tropics will be be at the poles.

The video also has a link to interactive software where you can change the tilt of earth to see temperature differences and the like. (I can't copy the link as I am on my phone)
