I think you will find your wheel type there (Turbo /Turbo I but you will need to decide) - if so the wheels are Fronts 8.0" 19" ET57 and 9.5" 19" ET46. The tyres will be 235/35 ZR 19 and 265/35 ZR 19.
The 305 tyres would be for wheels fitted to Turbo 911 cars, not wheels called "Turbo" style

Hi, I have decided to fit the correct tyres to my Cayman , the previous owner just had standard tyres fitted which look too small for the rim.
Can anyone help with the size of tyre please ?
I have an Aero kit fitted from New 20007 as a result I have 911 Turbo Rims , I've looked to see what tyres fir these rim's , I have I believe selected the correct size but no one can tell me ( tyre services , Porsche or Pirelli ) for certain.
Can anyone advise please is 305x30x19 the correct rear tyres , and if you can confirm front too please . I don't want to spend in excess of £500 for tyres which don't fit .
any help will be appreciated .

Do I understand correctly that you believe the tyres are smaller than the wheels should be fitted with?
If you cannot be confident visually identifying the wheel type/size, you'll need to check the inside of the rim of front and back where you will find the size information.
As Ralph suggests, the best way to check your wheel sizes is to remove the wheels - the wheel size should be embossed on one or more of the spokes.
The correct tyre sizes for the standard 19” wheels which I have on my 987.2 CS are 235/35 ZR 19 and 265/35 ZR 19.

When I look at a 2007 Porsche 911 turbo for sale, they have the exact same "looking" rims as mine. I then check the tyres to fit these rims buy using the turbo registration number, Black circles returns 235/35R/19 and 305/30R 19.
I would love to put the 305's on LOL. but I'm looking for something that fits inside the rear arch. thanks for the responses to date
Ken ( does no one else have a cayman with Aero kit )

As stated above, the first step is to be clear on your current wheels so that you can input the correct data to start with. The limiting factor on the Cayman is the distance between the spring carrier/damper strut and the wheel arch rim. I would not expect a 305 section to fit
As this thread has been revived, I finally got round to looking at Andrew's attachment of approved tyres. Is this up to date? No mention of Michelins for 981's except the GT4?AndrewCS said:See attached …
Not seen / heard of 305`s on a Cayman …
