The Forthing SX5 comes with 215/65 R16 tyres and 16-inch alloy wheels. The spare tyre is a temporary spare (T165/70 R17) mounted on a steel rim. For buyers considering the Forthing SX5, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
