it's a world standard "26 inch" rim.... not a Schwinn rim. you'll need to get tires that conform to a non-Schwinn standard.... and have normal beads that actually hook into the rim bead area, too.
the schwinn "fractional" labeled tires will blow right off the rim, probably... or not fit in the first place... which is what brought you to this forum with your issue.
by 1991, most Schwinns were already being made in Taiwan, to World standards. Schwinn fell victim to their want to NOT CHANGE, during the 80's... only the highest end schwinns were still made in the USA, and they were also switching over to world standards, and built with world sourced parts from various countries... "Schwinn approved" markings eventually disappeared from the derailleurs, brakes, etc., on the entire line of bikes....... the bikes became lighter, and much less expensive to maintain.
i have a mix Schwinn here right now... it has the heavy, small tubing frame, with a tiny, heavy seat post... and SHIMANO SIS derailleur and Shimano cantilever brakes, too.... it was already too late by then... the company collapsed, and the company's name was bought up.... Schwinn's famous name continues to help sell bikes to this day....
most of their Schwinn only franchised shops folded during the 80's... i have about a dozen 22(yep, ANOTHER tire size!) inch tires here from one of those shops... got them for free... and haven't sold a single one yet... pretty sure that Schwinn was the ONLY manufacturer to ever sell bikes with 22 inch tires... oops, huh?
they zigged when they shoulda zagged.
