For your Rodeo, changing from your selected 225/75R15 tyre on 15-inch wheels to 225/70R16 on 16-inch wheels gives a circumference increase of 0.40%. Nominal tyre width stays the same at 225 mm. With 225/70R16, 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.
If you want to increase wheel size further on your Rodeo, another option to compare is 235/60R17 on 17-inch rims, up from your selected 15-inch rims. Circumference decreases by 0.65%, while nominal tyre width increases by 10 mm, from 225 to 235 mm. With 235/60R17, indicated speeds of 30 and 60 mph correspond to approximately 29.8 and 59.6 mph respectively, assuming the speedometer was accurate with your selected original size.
For a larger-wheel look, 235/55R18 brings your Rodeo to 18-inch rims. Measured against your selected 225/75R15, this alternative has a circumference decrease of 0.39%; its nominal tyre width increases by 10 mm, from 225 to 235 mm. With 235/55R18, 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.
Choosing a wheel size increase for your Isuzu Rodeo
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 Rodeo 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.
