Moinmoin! Had ordered a set of summer tyres from a (allegedly) serous local tyre dealer (205/50/R17). In the sales interview various manufacturers and types were offered at similar prices. Among other things goodyear OPTIGRIP, which is marked with E/C, why he and others were rejected, because I drive a lot of kilometers and consumption is a criterion. In the course of the conversation also the goodyear EFFICIENC with B/A was offered, which was ordered thereon. e “because they drive a lot makes the most sense” (because of B/A-identification). The tyres were mounted on it, I had delivered the rims before. At home on the invoice I had to find out, these have E/C identification and not B/A. The type is indicated with goodear OPTIGRIP. The ordered goodyear with B/A would have been the EFFICIENC GRIP PREFORMANCE. Two hours later complaint on site, dealer apologizes it would have been no intention, the OPTI would have been a top tyre and points out with test from 2009. The objection he would have mounted the wrong tire with “have they already driven, it certainly rolls well” and other blablabla. He was not willing to respond to the complaint, brought tests with OPTI GRIP against the (old 2008) Efficienc GRIP, whereby the ordered B/A type should be a current Efficienc GRIP PERFORMANCE. I have now set a time limit in writing to keep the originally ordered tires ready for assembly and an appointment anz In the meantime, the vehicle is used daily. Simply NERVIG such a thing, so ALWAYS insist on a written order confirmation, with which one does not have to lament around afterwards and then goes to the lawyer.
