The back tyre on my bike keeps deflating and I can't figure out what it is. I did a long bike ride then a few days later, as my bike was sitting in the hallway, the back tyre exploded. The innertube completely split and the force ripped the actual tyre as well.
I replaced the innertube and tyre, but keep getting flats every time I go out. I have felt the rim and all seems to be smooth inside, so I can't work it out?
Any suggestions?
Mice with semtex?
lol, no, it originated from inside out, not outside in :p
Have you got a good rim strip fitted? Stretchy electrical tape is no good for example.
does sound like either you have a duff batch of tubes or there's something sharp on the tyre bead/tyre/rim that's causing this.
are the punctures always at the same point on the rim?
I don't know if I have a rim strip in there, I presume so, it's a Bontrager rim. It's so frustrating as every time I want to go on a ride it's flat. What puncture repair kit would you recommend?
I'm presuming the puncture is at the same point.
there should be some tape type stuff around the inside of the rim covering the spoke holes.
If it's damaged or too thin the edges of the spoke holes will puncture the tyre.
if you take the tube out, find the puncture and then lay it on the rim the same way round it was fitted you should be able to see where the problem is - run your hand around the rim and inside the tyre at that point to find if there's naything sharp.
occasionally you can get stuff embedded in the tread that you can't feel but with weight on the tyre pushes through into the tube so visually inspect the outside of the tyre at the point the punctures occur too and look for thorns etc stuck in there.
Some very good advice there wwawas, thank you. I will do what you said and see if the problem is in the same area. I will also check if the spoke could be causing the rubbing or puncture.
