Wheel for MTB on indoor trainer

[Spirog]

So, my wife has watched me get addicted to Zwift.

She thinks she'd like to join me occasionally for a little ménage a trois in my pain cave... ????????????.

I have a spare Cyclops trainer that I'll setup for her with her 27.5 MTB.

What wheel must I use to put a dedicated indoor trainer tyre on for her to use?

Do I use a standard 10 speed road wheel? Or do I find a spare 27.5 wheel? Is there a IDT tyre for the 27.5 wheel?

I suggest you get a spare mtb wheel (cheap or same as her normal one) with the same gearing. I use a standard mtb size slick tyre and it works fine imo no need for a specific idt type tyre.
