I want to exchange my unicycle tire with a Muni tire...

I want to exchange my unicycle tire with a Muni tire and my unicycle tire is
18 x 1.75 and what I want to know is what size is the tire that I
want to get? If you want to know how big my unicycle is watch my
video is shows, Oh and I am 4’ 8" tall. My unicycle is 30 inches tall.
Once more… I want to exchange my tire with a Muni tire and my
unicycle tire is 18 x 1.75 and what I want to know is what size is
the tire and/or tire size that would fit for my unicycle?
here is my video link:

You can’t put a MUni tire on your jugglebug, it uses 18x1.75 tires which is a screwy size that is only found on kiddy (no offense) unicycles. If you want to do MUni and probably other more extreme styles of unicycling like trials or street, I would suggest the Nimbus ISIS trials. It’s a bigger wheel than what you have, strong enough for when you get more extreme, and you can ride MUni on it somewhat decently. Since you are 4’8" it will fit you better than a 24" MUni and the smaller wheel size is more versatile for different styles. No real need to upgrade the cranks to KH moments since you are probably <100 pounds.

Hope this helps.

Thank you…

Thank you very much for the help, I now know what to do.
I way under 90 lbs. and I am a adolecent.
