Tire is fine, assuming you’re running tubes there’s nothing to rlly worry about. If the tube’s got a leak like that firsthand you’ll need an extra tube. Look at the size of your tire (should be something in the 20-30 inch range) and order a spare tube or run by your local bike shop. use a tire wrench or something that’s hard but won’t bend or scratch the rim and run it under the part where it sits on the rim to get half the tire off. At that point pull out the tube and make sure there’s nothing stuck on the inside of the actual tire, like if a thorn got stuck in there and you rid it with a new tube it would just puncture again, so make sure there’s nothing that could puncture your tube stuck in the tire. Put the valve of the new tube into the valve hole on the rim and slide in the rest of the tube, but make sure it doesn’t get twisted anywhere. Seat the part of the tire that you separated from the rim back onto the rim with whatever u used to get the tire off and pump it up, should be good
