Yeah, as the width is 285 too! The sidewall is a percentage of the width.

OEM tyres are 265 30 R20, so yours are quite a bit over with width and sidewall. This will over-read on the speedo too.

Use this calculator to get the % difference between OEM and your wheel the same or near enough.

You do need a 30 sidewall to get back close to the OEM tyre ratios. :)

It's because the 20" wheel the OP has is 11 inches wide. The 20s in the OEM wheels are 10 inch I believe using 265/275 tyres, so the tyre width is correct in this case, just not the sidewall.

You tyres look good! :)
Maybe we need to see the OP's wheels on the car to judge better?
