Hello everyone, I have last week together with my father last week the summer tires mounted on my SLK 230. Since then he pulls noticeably to the left and doesn’t drive as lively (could I imagine too). Since I don’t know so much and my father know more, but rather a “as long as he runs” mentality, I would like to turn to you. Tyre pressure fits, I checked several times. The winter tires (in which he drove super) are all four 205/60/R15 91T (https://imgur.com/a/SAiCCgE) are also relatively new according to my father, but I don’t have the exact date at hand. The summer tyres are in front 205/55 ZR 16W and in the rear 225/50 ZR 16W (https://imgur.com/a/mfwAL1D) and also relatively old, believe 2012. Profile is still there, however, as far as I can judge. After some googles I think it could be either because it wasn’t selected (which would be expressed by a fluttering rather than a pulling, od he doesn’t?), at the difference in the size of the tyres (in addition, none of the 8 tyres corresponds to the size of 205/55R16 91V specified in the vehicle license; but the car can also wear other shoes to my knowledge?) or at an incorrect track/axis/similar (but wouldn’t that be noticeable with the winter tyres?). As you can see, I have many theories, but unfortunately no expertise regarding cars. What do you think about it? Is it just time for new summer tyres or is it due to something different? rem? Rejoice me about your input. LG Philipp
