Definitely replace it. At this stage, with the rubber delaminating from the case, it could come apart at any time. It's dangerous to use. Near the bottom of the picture there are some bare threads. It is at that point the tire should have been replaced and perhaps only used in an emergency. PS I see from the picture that the rim is quite worn. It's not ...

What your bike can handle is usually more a matter of your skill level than it is the bike, at least to a certain point. When you watch mountain bike videos, you will see guys on hardtail "XC bikes" take drops much larger than 2 feet. BUT, they have skill, lots of practice, and likely many broken bikes or bones, or both in their past. Don't worry about ...

You must replace it. This tire is shot. I'm curious as to the brand/model of rims as well as the bike itself. Also, what surfaces are you riding on/

I use 23mm and 21mm tyres on my Mavic Reflex rims. It's fine.
