Problem with that is that most reviews are by cyclists (2 wheeled), which have virtually no relevance to how the tyre works on a unicycle.
And unicyclist reviews of tyres tend to be about that small numbers of tyres that are currently used on 29-ers and available from unicyclist.com.
Personally, I’m finding that none of that group are ideal for my riding- I’m not needing an extreme muni tyre (the WTB stout is too heavy for anything other than muni and is not good for the road hills local to me), or a ‘high-end’ road tyre.
All I need is a tyre with good tracking, not overly affected by road-crown, light (sub 700 grams) for hill climbs and, ideally, not totally slick so it can be used for mild off-road without being hopeless when it’sa bit wet.
For me, that leaves me using the Kenda Klaw 29x2.1- though it’s not as good at tracking as I’d like
see-
( 29-ers and the smaller tire advantage) for details
So, i’m very glad that some unicyclists do try out ‘unknown (in the uni world)’ 29-er tyres- after all, any of the current 29-er tyres that are well-respected, were once tried out as an experiment and found to ride well.
