Wheels help - 405M Mystery!

Hi everyone!

Ive just been to have some new tyres fitted on my 19's. Looked on the BMW at the 405M tyre sizes and ordered appropriately.

https://shop.bmw.co.uk/bmw-uk-respon...405-m/2219580/

Now - the current tyre size that (came already on) on at the rears is 255 and these are stretched quite a bit.

Can anyone help me identify what wheels these are and the appropriate tyres?

that link shows the spec of the wheels at:
" 7.5J x 19 with 225/35 R19 88Y RSC tyres and rear wheel size 8J x 19 with 245/30 R19 89Y RSC tyres."

255/30/19 will absolutely not be stretched on an 8" wheel. so either you are reading the size wrong, or your wheels dont match these specs....

This is what i mean, these wheels aren't the same size as the ones listed on the website, they are much wider... however i cannot find that they come in any different sizes.

I thought maybe they are M3 wheels or something?

You may have the F30 version and hence the different offset unless you have spacers?

Apologies, the F30 version is 18" or 20".

Best to read the part numbers and offsets on the back of the spokes. Could also be replica rims?

Pzero RFT have a very curved shoulder.
