I started with a 700x32c Continental Hometrainer tire. It seemed to work out OK at first, but in the last few times I've had to switch between my commuter/road tire and the trainer tire, it seems to have become more and more difficult to get the tire even around the rim. Tonight, I was putting it on, and I have pretty much given up. There is about a 6-8 inch section that is definitely not seating the bead to the rim, no matter how much I carefully work the whole tire around the rim as I inflate it. I've checked the inner tube, and it is not twisted or anything. It seems that the tire is simply small for the size of the rim for which I've gotten 28 x 1 5/8 x 1 3/8 commuter tires.
I'm looking for a recommended trainer tire to get as a replacement. I've searched via Google and Amazon, and there don't appear to be any direct 28 inch sized tires for trainers. Any suggestions?
