What I’ve found so far!
Over the weekend I hunted for 24" tires. A couple bike shops (Bicycle Village, Performance) didn’t have much selection for 24" tires. They were really cheap “mountain bike” type thread, that I just didn’t like and the max width that I found was labeled as 1.75, same as the label on the Kenda tire that came on the uni. I also looked in Target and K-mart, they carried the same cheap 24" tires.
Then I found a nice Specialized Holy Roller 24" X 2.1 tire at Turin Bicycle in Denver for $20. I thought this would be a nice upgrade. The tread pattern would be suitable for hard pack mountain bike usage. It has many smallish knobs as opposed to few large knobs.
Just to be scientific about it. I decided to measure the actual width and height of both tires while mounted on the unicycle rim and inflated to 33 psi. I simply used 33 psi, because that is what the Kenda was already inflated at. The height measure meant is from the inside of the rim between the spokes to the top of the tire. Of course this measurement will vary depending on the type of rim, but since I’m using the same rim, its accurate for my purpose.
Tire Label: Kenda 24" X 1.75
Description: Mostly smooth with small “street” treads and a solid center ridge.
Actual width @ 33psi: 1.71"
Actual hight @ 33psi: 2.1"
Tire Label: Specialized Holy Roller 24" X 2.1
Description: Small knobby mountain bike style tire.
Actual width (on tire casing, not including the knobbies)@ 33psi: 1.72"
Actual width (including knobbies) @ 33psi: 1.82"
Actual hight (on tire casing, not including the knobbies)@ 33psi: 2.1"
Actual hight (including knobbies) @ 33psi: 2.2"
So, as you can see, the label on the tire is a ball park figure at best. I’m out $20, but if nothing else, the new tire looks cooler.
By the way, the LX seat is way better than the CX seat. I don’t think the CIA would even subject prisoners to the CX seat, its that cruel.
And of course someday I’ll get a proper municycle, but for right now I have what I have and I know a wider tire will protect the stock rim better than a skinny tire, so I’m going the cheap route first.
