305 tires on 2008 C2S

[ultrarunner]

I'm new to the forum, recently traded in a 2006 cayenne S for a 2008 C2S. The best car I've ever had . My question is- can I place 305 size rear tires on my 19 inch turbo wheels or do I need to get a new set of wheels? Would appreciate the help. Also, I've put 900 miles on my car and yesterday had to top off my oil, is this normal?

305's with the 11" rim of the 997 turbo wheels are a perfect match. If I remember correctly the Turbo wheels are 8.5" wide, if that's the case I would run a 245 tire on the front to increase both front and rear by 10mm to keep the car from pushing even more.

Thanks Dave.

As Dave said 305's will be OK. I'm assuming you have the narrowbody verstion of the Turbo wheels - they will have the correct rear offsets.
