Suspected cause · Original poster
The problem is there are 265/30/19 on the rear but on what I suspect are 11" rims.
Leading evidence: 'are 11" rims' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'are 11" rims' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace might be possible' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I also use Wheel Size.com to establish what the factory fitment and offset is for a vehicle, before considering what changes might be possible.

Standard off sets are pretty conservative, which is why you can easily run a 15mm spacer on a 10" et65....

Alternatively, you may be able to run more camber, or run a narrower tyre to stop them rubbing (something like a 275.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi folks, do you know if an 11" rear rim with an et51 offset will fit the rear of a 996 C2.2 (narrow body)
Someone is selling a set of standard 996 wheels but they are 8" and 11"?? I'm just not sure what is what and have read loads. I'm slightly confused if I'm honest. I'm currently non 19" wheels and wanted a standard looking set. Many thanks for any help.
As HSC911 said - willtheyfit.com is very good :thumb:

Just select the model, year, engine size, find your current wheel diameter and then click on the '+' symbol to see the factory front/rear wheel size and offset.
Wheel Size also have a 'Tire Calculator' at the top of the webpage - similar to willtheyfit but a bit more comprehensive with more info and alternative options - saves ages working it all out.

For reference a NB 996.2 GT3 runs 11.0j x 18" rears with an offset of ET63.
The wheels you are looking at with an ET51 will be 12mm closer to the outside arch. I'd wager that 12mm may be a tad too much with the correct size tyres and you may need to tickle (roll) the arches to avoid rubbing. :thumb:

I had a look on willtheyfit but will need to find out the offset of the rear wheels that are on it at the moment. The problem is there are 265/30/19 on the rear but on what I suspect are 11" rims. The rear tyres are so pulled in it looks stupid and gives a very hard ride. I'm wanting to either put a 285 section rear on so it does not look silly (hope they don't catch) or go back to 18" wheels.
Sites like 'will they fit' will only tel you the difference in offset, not if they will actually fit your car.
Standard off sets are pretty conservative, which is why you can easily run a 15mm spacer on a 10" et65.... effectively making it et50.
But an 11" et50 (the equivalent of a 10" et 37) is going to be very tight unless you roll the rear arches - 996.2's arches are rolled, but 996.1's have a c.10mm lip inside the arch. Alternatively, you may be able to run more camber, or run a narrower tyre to stop them rubbing (something like a 275.
