It will only fit if your vehicle is approved for 195/40 R16 and your wheels are 16-inch diameter with a suitable rim width for a 195 section tyre. Check the tyre size on your current sidewall, your handbook, or the door jamb placard, and match the recommended size plus the load and speed ratings. If your car currently runs a taller profile, also confirm there is enough clearance at full steering lock and over bumps to avoid rubbing.
195 is the tyre width in millimetres, 40 is the aspect ratio (the sidewall height is 40% of 195 mm, roughly 78 mm), R means radial construction, and 16 is the wheel diameter in inches. Because the sidewall is relatively short, this size is less forgiving of incorrect pressures and pothole impacts than taller profiles, so choosing the right specification matters.
Use the load index and speed rating shown on your vehicle placard or handbook, then match or exceed them when selecting 195/40 R16. Do not downgrade ratings, as that can be unsafe and may invalidate insurance. If you are unsure between two options, choose the one that meets your car’s stated requirement and suits how you drive, then confirm with a fitter before installation.
Switching to 195/40 R16 reduces the overall tyre diameter compared with 195/45 R16, which can affect speedometer accuracy, gearing and ground clearance. Even if it physically fits, it may not be an approved size for your vehicle. Stick to manufacturer-listed sizes where possible, and if you are considering a change, check the permitted alternatives for your exact model and trim before ordering.
Yes, but the choice can be more limited than more common 16-inch profiles, so it is worth comparing brands early in the season. For winter performance, look for the Three-Peak Mountain Snowflake marking; for year-round use, an all-season option can be a practical compromise. If availability is tight, confirm your car has an approved alternative size before switching, rather than forcing a different fitment.
