I'll assume there are not many but if anyone has info it would be great.
Just because I'm looking to run a 225 and it would be a better fit on the 7.5 width.
Thanks

 

there are 3 sport edition and 1 rial wheels in 16x7.5 on this page for the MINI.

What suspension upgrades do you have or are planning?

225mm wide tires and 16" wheels are possible.

225/40-16 Fits rims 7.5-9" wide, 23" tire diameter Toyo T1R
225/45-16 Fits rims 7-8.5" wide, 24" tire diameter
225/50-16 Fits rims 6-8" wide, 24.9" tire diameter (tall for lowered suspension, ok for stock suspension)
225/55-16 Too tall for MINI wheel well

So in most cases you can run a 16x7" rim with about +38mm offset and 24" or smaller tire diameter with little trouble. If lowered then watch the offset.

16x7.5" rims are possible with Rota wheels but not all are that width.
Some are 16x8 with +34 offset.
