16x3.0 Tire

I am not sure if this has already been posted, But the smaller sting ray has a 16x3 rear tire. A little bit ago many people were talking about the advantages of a 16" trials unicycle, so I thought I could make you aware of this tire. It could be good for high jumps or something.

I think someone already discused these but so you could have a 3" wide tire on a 20" rim. But they said it wouldn’t work because the side walls on the tire wern’t made for trials so it would fold often.
