Is this normal? These tires are "Vittoria Mezcal XC Race 29" TLR MTB Graphene 2.0 Folding Tire". Not even 1.5 year old and I did 1070km on them, on tarmac and gravel, mostly in the summer. This is in Greece, so it's pretty hot.
They're now suddenly starting to leak all over and I noticed these cracks in the sidewalls. I had to add a lot of sealant to make them stop leaking. Is this still safe to ride or should I expect a catastrophic failure any moment? Do you think it's warranty? I expected the tires to last until the thread wears out.
