I have a 24" X 3" rim. A 30X3 clincher is too big. What tire do I need? thanks
Don

Too big how? Width or diameter? A 30 x 3 clincher takes a 24" rim. If you are having trouble getting it squeezed together enough at the valve stem, some folks trim out a radius to clear the stem. I've never had to do this, but I have taken some off that were done that way.

The diameter is the issue. cant get tire edge under clincher all around.

What do you about the history of the rim?

Has it been driven on around the back 40 (or maybe pavement) without a tire, and thus collapsed the area that should receive the tire edge?

Don,

From the little that has been shared so far, "IF" the tire you have is marked 30 x 3 and "IF" the opening in the tire is too large, then I would "GUESS" you have a 30 x 3 1/2 rim that you are trying to mount the tire onto.

Remember the Canadian non-demountable front wheels were always 30 x 3 1/2; the USA produced Ambulances during WWI used 30 x 3 1/2 front wheels; and some folks switched to 30 x 3 1/2 front wheels so they only needed to carry a single spare tire.

Compare it to you back wheel and see if they are the same or not.

Respectfully submitted,

Hap l9l5 cut off

Don, as you probably figured out, you measure inside the rim to inside on the other side, not from the outside edge to outside edge. Inside is the point closes to the center of the rim that the tire touches. As they told you, you measured the rim incorrectly and you need a 30 X 3 1/2.
