Topography and tire wear [Surface-Topography Challenge Update, April 2026]

Dear STC Community, 

1. This month’s featured investigation: Rubber wear – Experiment and theory

   • Bo Persson et al measure the wear of a simulated tire/road surface and show how measurements match with theory.

   • They incorporated the STC samples into their experimental investigation. (They get the award for first citation to the STC paper; in fact, before it was even published!)

   • Read the full paper here.

2. Welcome new members!

   • Since launch, we continue to get additional requests for samples, and sign-ups for the newsletter. Thank you for joining us on this adventure.

3. TriboNet webinar.

   • Our friends at TriboNet featured a webinar on the STC. Check it out here.

Take care,

Tevis, Arushi, Simeona, Martin, and Lars
