Rough translation:
My wife has purchased a 16 inch steering wheel cover and my vehicle has a 16 inch steering wheel; however, the cover seems to be too small. I do not wish to damage the cover so I wondered if any of you good chaps had any experience of fitting steering wheel covers? If so, I would be most obliged if you would advise me as to whether you believe the aforementioned cover will fit.
To answer the question - Yes, I would think that a 16" steering wheel cover would fit a 16" steering wheel. If it's leather, I believe the best course of action would be to heat up the leather first, but the instructions should explain the best way to fit the cover.
