Hi everyone! Trek Domane AL2 owner here! I changed my R1 stock tyres to a set of Vittoria Zaffiro pro graphene tyres in May. I just discovered these cracks just now while inspecting my bike. My question is, are these cracks something I should worry about? Sorry if my question sounds inane. I’m still relatively new to cycling. Appreciate any advice or help I can get. Thanks in advance.
