I have had buggies with air-filled wheels for 10 years but seem to be getting punctures all the time at the moment.
I've never used slime because I was worried that it would make the buggy heavier to push but I admit that I don't really know how it works so could be totally wrong.
The pushchair which is causing problems at the moment is my ABC triple. I bought a few inner tubes from go outdoors (cheap) and the wheels always seem to be flat when I go to use the buggy. There is still tread on the tyres but I'm considering buying new tyres and inner tubes in the hope that I'll be puncture-free for the foreseeable.
Any tyre/inner-tube recommendations? Is slime worth doing or will it make an already heavy triple buggy impossible to push up a big hill? Should I go to a proper bike shop or any online recommendations?
