am waiting to take delivery of a new cayman and have a question.
am looking to add a spare wheel and have used the search function to find the section on adding a spare wheel but am a bit unclear as to the size i actually need ( i've ordered 19" wheels).
i've come from an audi TTRS which i added a spare to and am wondering if the one i have at the mo will do (125/70 r18 99m et25.5)
thanks guys.
 
thankyou for that. that's the section i have looked at but unfortunately it doesn't give the et ( offset) or pcd for that matter.
 
The easy option if there is one is to check if there is a spare wheel kit available, it would include the wheel, tyre, wrench and jack. The spare should be able to fit the front and in the instructions of the 968 which carried a spare, if you had a rear puncture you were supposed to transfer the good front tyre to the rear and use the spare on the front! Don't ask me why as it would fit either hub. So far, I'm unaware of the clearance needed for the brake caliper etc or offset which may have changed for the 981 but would expect that Porsche will have stayed with their std 5 stud spacing on a PCD of 130mm.
 
You could try contacting your nearest PC or someone like The Porsche Shop or Design911UK for information on wheel diameters and offsets. Of course, you could always wait until you have the car and check out clearances with your Audi spare. Whatever, you're going to find it a tight fit carrying a spare wheel along with your luggage..! Might be best to rely upon the tyre repair gloop provided and RAC back-up if necessary (I believe that they carry spare wheels to get you to a repairer). Jeff

thankyou for that to be honest not bothered about luggage.... single guy and all that. as for the tyre sollution i actually work for the oposition to the RAC and can i say that gloop is totally useless and we can't understand how car manufacturers get away with not supplying a serviceable spare wheel. next time i bump into an rac man whilst i'm driving my yellow truck lol i'll ask about the spare wheel.
 
The reason I mentioned it Danny is that I have 19" wheels on my 987.2 and I'd really struggle to get to get one of the rear wheels in the front boot. Of course, the boot could be slightly larger on the 981 you've ordered. I seem to recall that Richard Hamilton did an interesting and comprehensive post on the subject last year. You could try emailing/PMing him to get the post. You may want to ask your PC about the RAC support in the event of a puncture. It could be that the Porsche support centre coordinates the response with the RAC to ensure that a specially-equipped vehicle is sent out. Good luck. Jeff
 
thanks for your reply jeff. looking at the section of how to add a spare wheel the suggestion is that the rear wheel would/could fit ontop of the engine cover in the cockpit albeit with the seats moved slighly forward. will try contact the person you named.
 
Yes, I think that's what Richard H did Danny. I seem to recall that he purchased a used (997?) spacesaver spare wheel which fitted in the front boot and found that he could just get a 19" rear wheel on top of the engine cover - but it was a tight fit..! That's on a 987 of course, and you'd need to check this out on your 981 when it arrives. Keep us posted on the arrival of your new car and your impressions too, particularly wrt your Audi. Jeff
 
There is no way a 19" rim would go in the front!! surely?! how come you want to lug a spare? would an extra puncture repair kit (or two) not suffice for long trips?
 
the spacesaver i have is an 18" but its rolling circumference would be ok to put on a car with 19" wheels. from my personal experience the repair kit is totally useless.as i work for a well known motoring organisation the number of times i have to deal with cars with punctures and these kits that will not repair tyre damage caused by punctures.the only option is to be taken to a tyre garage, which isn't open at 2 in the morning and on a quiet country lane. thats the reason for a spacesaver .
