Hello all, I have on the rear axle two WINTER REIFEN 245/45R19 102V NEXEN WINGUARD SPORT 2 with good profile. The front tyres should be replaced by the same model, because of a wrong order I get now instead the Michelin Sport Alpine 5 245/45R19 102V . Who of you has experience with mixed tires? Is it worth it for me now in two more new Michelin to avoid possible disadvantages or even dangers by mixed tires? LG
