Any question answered...

I've scoured the tyre threads and not come up with anything....

Which big volume (35 ideally) puncture resistant 700C slicks? For my cross so skids not an issue. The conti cyclocross folding that came with the bike have the puncture resistance of an eyelid.

I have the 32c Panaracer Ribmo on my Crosscheck for Nursery Runs and commuting duties. Only about 2 months in but I have not had a single issue, YMMV.

peckham bmx track? Also Brixton beach if you think he won't be scared of Object.

My 19 month old is not afraid of Object. He's quite fond of him really.
