I am new here and have a question about my BMW 1 Series 118d.
Last year I bought this used with a mileage of 143000 km. At that time there were 4 Zeetex HP 2000 vfm summer tires with the dimension 225/50 R17 93 W extra load on them. Already there I noticed how spongy and bad the driving behavior is. The track was set and the tire pressure changed. With that, I was able to make up for it halfway.
Then came the winter tires Bridgestone Potenz with the dimensions 195/55 R16 87 H and BMW Stern. With these tires everything was great, great driving experience and nothing to complain about.
Four weeks ago I put the summer tires back on. 2 of the Zeetex had to be exchanged, so that I now drive on the rear axle with 2 new Dunlop Bluresponse and in the front with 2 Zeetex tires. Dimensions are the same with 205/50 R17 93 W extra load. The driving feeling is really shitty and spongy again. I have tried all print versions, nothing gets better.
In the front I have the feeling that the tires are hopping a bit and when changing lanes or moving the steering wheel quickly, the rear is very restless.
Anyone have any idea what else I can do to get this grip on summer tires under control?
Thank you in advance for your advice.
