Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What does 195/45 R15 mean?
195/45 R15 reads as: 195mm tread width, sidewall height 45% of width (≈ 88mm sidewall), and a 15-inch rim diameter. A complete size includes a load index and speed rating, e.g. 195/45 R15 91V.
Can I fit a different size to 195/45 R15?
Only fit a size approved for your specific car. Changing width, profile, rim, load or speed rating affects handling, braking, fuel economy and MOT. Approved alternatives are usually listed in the vehicle handbook.
Where do I check 195/45 R15 is the right tyre for my car?
Compare 195/45 R15 to: (1) the size already on your sidewall, (2) the placard inside your driver's door, (3) your vehicle handbook, and ideally (4) a tyre fitter familiar with your model. Don't fit a size that doesn't match all of these.
Can I read 195/45 R15 backwards from a wheel listing?
If you only know the wheel — for example a 15-inch alloy with width X — the tyre size is usually engraved or labelled separately. Don't assume from rim diameter alone; many cars run different widths and profiles on the same rim size.
What do EU tyre labels show for 195/45 R15?
Every new tyre — including 195/45 R15 — carries an EU label rating fuel efficiency, wet grip and external noise. For UK driving, prioritise wet grip first.
