View attachment 36594 This stuff excuse the size tyres are all new or 100 miles etc all punctures on the tyre side, not from the rim all tyres are clean ?!
This is a tyre liner - long piece of flexible plastic - which confusingly is a Slime brand.
Opinions vary, but a lot of people have found a liner causes more punctures because it shifts in use, pinching the tube.
