Hello, I have 2 different tires on the car behind Bridgestone and front the Dunlop SP Sport Fastresponse . At the back the running direction on it is so now to my problem: On the front tire stands right and left “outside” on it only runs the profile differently to each other! Since I have the on it stands my steering wheel slightly crooked and my consumption has increased by 0.7 liters. How do I not get through what is wrong? The workshop dismantled them and according to their Besch rubbing(creath on the tires) were at the front right and left once Bridgestone and once Dunlop mounted (at the back the same) so different tires per axle. Greetings
