Tomorrow, my girlfriend’s (old) new panda knows the following problem, better the CEC3. The tire is (despite correct track/sturz) one-sided, apparently typical of this panda original tire. It looks like the following (longitudinal grooves from the outside to the inside): 1.8mm profile depth, 4.2mm and 3.8mm. In all three rooms there are the index markers. Attention: this is not about the safety aspect but about the legal side. My question: where must the 1.6mm exactly m be edible? Thank you very much
