195 is the tyre width in millimetres, 80 is the profile (sidewall height as a percentage of the width), R means radial construction, and 15 is the wheel rim diameter in inches. After the size, you will also see a load index and speed rating, which must meet or exceed your vehicle requirements.
In most modern listings, 195R15 is commonly treated as 195/80 R15. Always confirm the full marking on the tyre, including load index, speed rating, and whether it is a commercial C-rated tyre, before ordering a replacement.
Many vehicles that use this size specify 195/80 R15C, which is a commercial tyre with reinforced construction and higher load capability. Check the tyre placard or handbook for the exact load index and whether C-rated tyres are required, then choose a matching specification so you do not downgrade load capacity.
Changing from 195/80 R15 alters overall diameter and sidewall height, which can affect speedometer accuracy, gearing feel, clearance, and how the vehicle sits. If you are considering alternatives, match the manufacturer-approved sizes for your exact model and replace tyres in axle pairs with the same size and specification.
Yes, depending on brand and stock, you can find all-season and winter options in 195/80 R15. For colder months and snow-prone areas, prioritise tyres marked with the 3PMSF symbol, and for year-round UK use consider an all-season pattern if it matches your required load and speed ratings.
