Hi Roman, I have sent you a PM with my contact details. Kind regards, Peter

Gunther, Loren, Thanks for your input on this. I had the 295x35 tyres fitted last week onto BBS RXII 21" alloys and it appears that offset and tyre size is no problem. 295 x 35 on the big RXII 21" alloys look great ! I have got one extra spare (brand new) set of the BBS RXII 21" alloys - any idea on a good website / place to sell them in Europe (I am London / Prague)? ebay is too generalised for this type of stuff. I have 3 sets of alloys, which rather sadly is one more than my wife says I need ;) Anyway, thanks again for your help, Peter

Loren, Thanks very much for your help. I'll report back if I learn anything useful... Peter

So can I recap? 1. 295 x 35-21 will fit onto 21 x 10.5 rims but 2. the unknown is whether the extra tyre diameter (offset) causes an obstruction inside (wheel arch cavity) or outside(wheel arch itself) Is that about right? Thanks.... Peter

Hi Loren, Really appreciate the info. I am happy that 10.5 x 21 work on the car as they were supplied by Porsche main dealer and drove beautifully for 2 years. I know that Porsche fit 295 x 35 tyres onto 10 x 21 rims. Would you expect any problem fitting the same tyres to 10.5 x 21 rims? I have researched but I don't understand how the tyre get's matched to the rim - is it just rim size? How does the rim width (10.5) impact the tyre specification (the 285/295 bit)? Appreciate your help, Peter

Hi, I have a 2005 Cayenne Turbo which came with BBS RXII 10.5 x 21 (part RX519) rims. I need to buy new tyres and wonder what size tyres these rims will take? I know I must use low profile 35's but not sure whether I can I use 295 x 35 ? BBS don't issue a spec (unless it's in german!), tyre sites seem to recommend 275's but the rims I bought came fitted with Dunlop Sport 285's. Porsche now seem to support 295 x 35 on 10 x 21 rims. Confused? I am ! Can I use 295 x 35 on a BBS 10.5 x 21 rim is the basic question I guess! I have searched and can't find the info on the site but any redirection to an existing answer very welcome. Thanks, Peter

PCM

Appreciate the information. When I get this done, I'll update the post with confirmed version numbers etc. Although at 400Euro+ for a map update from Porsche, a TomTom unit (with daily internet updates) is starting to look a very solid proposition ! -

Thanks for the response, really helpful. Do you know what version PCM software I need to get to in order to update the Navteq map disk ? The local Porsche garage didn't know that the PCM needed upgrading so I'd rather be sure of what needs doing ! I'll check out how to become a "contributing member"... Thanks again. -

Thanks for the tip. I can probably get a free update from a contact at Navteq if I know what to ask for ! What version PCM supports what version Navteq etc etc ? Thanks... -
I eventually got enough money to live a bit of the dream and got a Cayenne Turbo purchased in Germany (if that makes any odds!). The car was registered in March 2005 but manaufactured 2004 I think. I need to update the Nav system for Europe from Navteq 10/2004 but am confused about versions... What do I need to check before I update ? What is the whole V1 / V2 issue for PCM ? How do I check Nav version ? I think there is a 2006 update ? All help gratefully received ! :notworthy: Thanks, Peter
