Is there any rule of thumb about width rim you need to fit a particular width of tire?
Specific Example: I just ordered a hookworm 24" 2.5 to put on my semcycle XL. Will this work with my stock rim? (I don’t have the specifics because I’m at work, but I don’t remember it being very wide) Do I need to buy a wider rim?
Try it out, it should be ok. Gazzaloddi’s recommend that you use a rim that is at least 28mm for 24x3" tires, but Joe uses an extremely narrow rim on his MUni. I think he finds that it is not ideal, and that the tire folds over or bottoms out sometimes, but it works most of the time. His rim is probably way narrower than most stock rims so yours should work. Depends on what kind of ride you are looking for I guess.
It’ll work. I run the 24x3.0 fireball on a sun rhynolite. I also used to run the untense 24x3.0 on it for muni. Your tire folds a occasionally, but it’ll work okay. Just carry a pump in case the rie shears off the rim.
As for the ride, I haven’t reached Mike yet, but if it happens it’ll be on saturday or possibly friday, but definitely not thursday, and highly unlikely sunday. Worst comes to worst, it’s just us two.
