Lads, need some novice advice.
Was out on the bike yesterday for a short climb, bike felt fine.
Went out today, got about 200 yards before realising back tyre was flat. Pumped it up, no hissing or sign of puncture. Went out, 2km in realised it was semi flat. Went back home, changed inner tube, checked for anything nasty in the tyre, nothing.
Went out and did a short 22km with a steep climb, bike felt good. Got home and tyre was half flat again. Checked it an hour later and it was completely flat.
Is the tyre f**ked or am I pumping it up too hard or wtf is going on?
First time id changed an inner tube in 15 years earlier, definitely don’t miss it!
