Recently, I discovered some ugly cracks on the sidewalls of the two Schwalbe Marathon Plus tyres installed on my bike. I noticed them after having a flat on the rear tyre. Both tyres have the same symptoms. The tyres are 5 months old, and they have only 2.200 km.
I looked on the internet and I read on Schwable's website a new version of the Marathon arrived on the market. It's written :
"In everyday life bicycle tires are frequently ridden with insufficient air pressure and thereby become overloaded. After this kind of "abuse" cracks can appear, so Schwalbe redesigned the sidewall. The tire will now tolerate this "low inflation overloading" for much longer before ugly cracks eventually start to appear."
However, the min pressure written on the tyres is 3.5 bars, and I regularly check my tires pressures and I make sure it's always between 4.5 bars and 5.5 bars
Does anyone go such a problem with Schwalbe Marathon Plus tyres ? I sent an email to Schwalbe, but I still waiting for their answer.
