I noticed this hole when I got to work in the morning. It lets out enough air that I can hear it when I try to inflate the tire. What are my options here, aside from buying and mounting a new tire? Is this fixable with liquid sealant? A rubber rope kit?
I'm not taking this bike past 90mph, so any fix doesn't need to be capable of withstanding incredibly high stress. But I don't want to be unsafe, either. Thanks for the help.
You already have good answers. To add to the reason why this tire is dead is it is a slice not a hole. When you get a hole from a nail in your tire it usually goes between the belts. With a slice like this. It is much more likely that belts have been cut. This means the strength of the tire is compromised. If I was out on the trail or just trying to get home I would plugged it for the short term. So if you need to ride it to the shop to get a new tire you should be fine, but this is not a tire to trust your life with.
