Hello, the background is that our vehicle does not have a spare wheel pit, since there are the tanks for the gas. Now the latest generation of Runflat tires should not be so uncomfortable anymore. A set of 16″ winter tires with steel rims (205.55,R16) costs around 700 euros! Sometimes a tire is also at 200 euros. The best would be the TS830 from Conti. The prices are from Reifen.com. Can it not be cheaper, with Runflat?
