Hello. For some time now I have been driving with a Ford Transit (2011) for a freight forwarder, with the tire dimensions 195 / 70 R15 C. Now I had driven the vehicle until last week with summer tires. Thus one could drive for a transporter quite sporty, and on the BAB the top speed (approx. 160km /h) without problems take advantage. Now the transit got brand new winter tires of the brand Uniroyal missed with the same size as the summer tires. However, the Transi floats The car swims extremely, in my opinion, with slight steering movements as you have to do from time to time (overtaking / dodging on the BAB) even the ESP goes on! Is this normal that this is such a difference? I had not experienced anything like this in any vehicle up to now and I already have many dangers. Thanks in advance. MFG
