Citroen C4 tyre size conversion explained

For your C4, changing from your selected 195/60R18 tyre on 18-inch wheels to 295/35R19 on 19-inch wheels gives a circumference decrease of 0.30%. Nominal tyre width increases by 100 mm, from 195 to 295 mm. With 295/35R19, indicated speeds of 30 and 60 mph correspond to approximately 29.9 and 59.8 mph respectively, assuming the speedometer was accurate with your selected original size.

If you want to increase wheel size further on your C4, another option to compare is 265/35R20 on 20-inch rims, up from your selected 18-inch rims. Circumference increases by 0.33%, while nominal tyre width increases by 70 mm, from 195 to 265 mm. With 265/35R20, indicated speeds of 30 and 60 mph correspond to approximately 30.1 and 60.2 mph respectively, assuming the speedometer was accurate with your selected original size.

For a larger-wheel look, 275/30R21 brings your C4 to 21-inch rims. Measured against your selected 195/60R18, this alternative has a circumference increase of 1.04%; its nominal tyre width increases by 80 mm, from 195 to 275 mm. With 275/30R21, indicated speeds of 30 and 60 mph correspond to approximately 30.3 and 60.6 mph respectively, assuming the speedometer was accurate with your selected original size.

Choosing a wheel size increase for your Citroen C4

Standard and original equipment sizes

Check the standard or original equipment tyre and wheel sizes approved for your exact engine and trim. A size recorded against this model may belong to another version. A genuine manufacturer wheel option still needs to match your vehicle; these calculated alternatives are close size matches, not confirmation of manufacturer approval.

Speedometer variation and effective gearing

Keeping circumference close to your original tyre limits changes to speedometer and distance readings and effective gearing. A larger circumference makes gearing taller and increases road speed at the same wheel speed; a smaller circumference makes gearing shorter. The gearbox ratios themselves do not change. The estimates above assume the speedometer was accurate with your selected original tyre; existing speedometer error and actual rolling circumference can change the result. The ±3% filter is this converter’s comparison threshold, not a manufacturer approval or a guarantee of fitment.

More wheel, less sidewall

A larger wheel paired with a lower-profile tyre can give your C4 a sleeker, sportier appearance while keeping overall diameter close to the original. A shorter sidewall can also mean a firmer ride and less cushioning over potholes.

Tyre width, offset and full-lock clearance

Keep width increases modest and check clearance around the suspension and inner wheel arches at full steering lock and through suspension travel. Tyre width, wheel width and offset all affect whether a wheel fits without rubbing. Nominal tyre width is the section width, not the measured tread width. Choose a compatible wheel and offset for a spacer-free fit; spacers are not an automatic remedy for fouling. Confirm brake clearance, load and speed ratings and the exact vehicle application before fitting.

Results compare nominal sizes. They do not confirm vehicle or wheel fitment.
