My bicycle tire has a puncture and while I have a pump with me, I don't have a patch repair kit. Is there a way to keep the tire from running out of air until I can get to a bicycle shop?
One way to temporarily fix a punctured bicycle tire without a patch repair kit is to insert a spare inner tube, if you have one. Alternatively, you can try filling the tire with a sealant like Slime, which can temporarily seal the puncture. Another option is to use duct tape or a similar strong adhesive to cover the puncture on the inside of the tire. However, keep in mind that these are temporary solutions and you should replace the inner tube or repair the tire as soon as possible.
I don't have any of those products, is there anything I can use that isn't a specialized product?
Duct tape and strong adhesives listed above are not specialized products and are available at most hardware stores. Of course, to reiterate, it is suggested to replace your inner tire as soon as possible.
