Thanks Majid,
You have obviously done a lot of reading on this, and so you will know the importance of matching the outside diameter of the new wheel and tyre, with that of the current set up. So width for width you will need to reduce the tyre profile. Since it’s Christmas Eve, I’ll leave you do the maths!
You mention one tyre width will result in a tyre clearance of 0.7mm ( around 30 thousands of an inch!) between the tyre wall and the suspension leg - just totally and dangerously unacceptable to me.
Kind regards,
Gareth.
