Hello together As the title already says, I am looking for alternative winter tyres for my small streamer and hope you tire gurus have a good tip for me. Normally the Twizy is equipped with Continental WinterContact TS800 which I have installed at the moment, but as with Conti as usual the slats disappear at 5mm residual profile thickness and accordingly the grip in the snow gets bad. In addition, the Conti still demands a lot for the offered performance. I live in Switzerland I have the advantage that I can play with the tyre size in a certain way without having to dance at the test site.The following tyre sizes are allowed to my level of knowledge: Front 125/80 R13 (series), 135/80 R13, 145/70 R13 (special case see below) Rear 145/80 R13 (series), 155/70 R13 The speedometer signal is calculated from the speed of the electric motor and this drives the rear wheels. My problem is now the front tyre size and unfortunately most manufacturers of the corresponding sizes don’t tell me anything. As mentioned above, the size 145/70 R13 front is a special case where I don’t really see through: In the Vectorix forum several users do not fit the winter tyre in 145/70 R13 > in summer I drive this size myself (M chelin ENERGY E3B 1). The most important criterion that the tires must meet is gripping in the snow > I live in a valley and need to work over a small mountain whose road is not blacked out. Thank you for your help
