I hope I'm asking this in the right place.I just aquired an adult trike in project condition.It's a Cignal brand which I've been told is a low end bike shop brand.I have wanted to try one out for a while and build it a bit custom.It has a 24 x1.75 tire on the front but both rears are gone.I'm wondering if I can use a 24 x2.125 on the sam rime.Inside bead to inside bead is 7/8 ths of an inch.I don't want to spend a lot of money initially until I determine which way I want to go with it.In looking around for info I have gotten very confused.I would like to run a fatter(Maybe cruiser type tire on the rear) and a 24 x1.75 on the front. In looking I found a "Cheng Shen" C241 (for rears) and c727 (for front).I didn't find a post on tire sizing so ....
BTW Use will probably be mostly neighborhood cruiser and grocery getter.Most initial rides will probably be 1.5 miles or less.After that I may consider upgrades.

The short answer is that, if the rims are otherwise in good shape, 2.125 should be fine. The rule of thumb is "max tire width = rim bead width x 2.4. That's really very conservative.
See Sheldon Brown's discussion here: http://sheldonbrown.com/tire-sizing.html
Also, of course, make sure you don't use tires that require hooked rims on rims that aren't hooked.

Thanks for the info.I was pretty sure I had it right but didn't want to go thru the hassle of a return on an internet purchase if I was wrong(it's happened before but that may be because I'm married).I appreciate the answer and will probably have to wait for a few weeks to make progress,I'm leaving on a 3 week trip to Tx next week.I will be documenting what I do so if I can figure out how to post pics I will.
