I’d not heard of CST but having a dig appears to be a budget brand compared
to more premium Maxxis both of which are owned by the same company.

But would explain the longevity as generally speaking more budget friendly
MTB tyres do last much better. Used some on the old MTB/Commute bike and
seemed to last a few thousand miles, not as long as the BigApples but
certainly a lot better than posh MTB tyres.

As ever with life are compromises I had some mid range Continental tyres
few years back that I ditched after a very hairy descent of one of the old
industrial inclines near my folks place in Wales which was wet steep and
plenty of rock slabs which the Conti’s where very skittish over.

Magic Marys and Hans in a soft compound handle the incline without fuss,
it’s still steep and a wet slippery environment but much more controlled.

I suspect so yes!
