Hello, I am looking for the optimal winter tyres. So not all year round tyres, but which are optimal in cold, wet and snow. The size is 120/70-12 and 130/70-12. So far I have come across these two tyres due to research on the internet and recommendation of dealers: 1. Kenda K701 Winter 2. Heidenau K66 LT M+S To the Heidenau K66 LT M+S I received the following information from the manufacturer compared to the Heidenau K58mod M+S: The tread mixture (Snowtex) is the same, abe r the K66 LT M+S also has lamella technology, so it is better suited for snow-covered roads. From the profile picture the Kenda K701 winter also seems to be equipped with lamella technology, whereby at the Heidenau K66 LT M+S the profile is crossed with more grooves. Unfortunately, I have the impression with some dealers that they simply want to get rid of the tires that they have in stock… So a quite expensive dealer recommended to me the Heidenau K58mod M+S, although I had communicated, next questions: What is a realistic price for a tyre change? Does it make sense to buy a set of rims for the winter tyres? Thanks for helpful answers! Greetings Tanja
