These are great, saw them a little while ago but didn’t know much or that there is a series of them. They’re produced by graphic design studio Intercity. Designed by William Hibberd, the Tread print series was born out of an obsession with bikes (plus early memories of friends comparing tyre patterns) and documents a selection of the most interesting graphic shapes and patterns found on everyday bicycle tyres. See more over at Print Process (along with a heap of other good work). Studio photography by Dom Moore.
