Astonishing. How many miles did you put on them? Blue means Marathon+ and those are typically good for many thousand miles. I've pair of Marathon green on one of my Bromptons and maybe put about 1500 km on them until now. They show barely any signs of wear if any at all.

The whole point of the M+ is puncture protection. If you do not like the thickness I'd suggest using another tire - like the Marathon Green, the Marathon Racer or the Brompton Kevelar... All of those are thinner in that aspect.

Over here I pay (when buying online cheaply)
13,30€ for the Kojak,
13€ for the Marathon Green and
20€ for the Marathon +. Not really expensive. All last at least serveral 1000 kms, with the Kojak having the lowest endurance milewise. I'd assume the Marathons last at or above 10.000 km.
