Looking to get some snow tires and wanted to clarify if this set will fit?
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.

Wanted to know if the following wheels will fit my 99 C4 narrow body. Looking to get some snow tires and wanted to clarify if this set will fit?
Snow tires on factory "solid spoke turbo twists" Fronts wheels are 8x18" (50et) offset, front tires are 225/40VR/18. The rear wheels are 18x10" (47et) offset, rear tires are 265/35/VR18.
and
summer tires on 18X11" (45et) and two 18x8"(50et) "hollow spoke factory turbo twists"
Thanks in advance
I don't think the rears would work. Both, 10" (ET47) and 11" (ET45) were designed to work on widebody 996's. What works on the narrow body is 10" (ET65).
Just spoke to Manhattan Motor Cars in NYC and the service guy told me that a (47et) offset, rear 10' rim with 265/35/VR18 tire is ok. So I'm confused now, is the 47et ok. Should I go for it or not?
Of course he will tell you it is ok. But to get the proper wheel you need to go with the 65 offset in the 10" and 63 in the 11".
The Boxster can handle the 10" rim with the 47 offset (what porsche has for the 986)
Rears according to Porsche:
986 8.5" 48 9" 52 10' 47
996 (NARROW) 10" 65 11" 63
Uh, Porsche never specified a 10" wheel for the 986. The following is what was fitted on the Boxsters rear:
7" x 16" - ET40
8.5" x 17" - ET50
9" x 18" - ET52
The 10" with the 47 mm offset is strictly approved for the widebody 996. That's not to say it doesn't work on some other models including the Boxster.
Here's the deal. The 65 mm offset 10" wheel sit very close to the rear fenders. The 47 mm 10" wheel will come 3/4" farther out from that. Do you want a wheel that potentially might cause the tires to rub? I wouldn't.
Actually Porsche DID specify that (for the sport techno). Take a peek at the Summer Wheels and Tires Teq2004 bulletin.
For the Rears:
8.5" is 48
9" is 52
10" is 47
so 8.5" is 48
9" is 52
10" is 47
and these numbers are for the 1999-2000 narrow body? so guys but I want to make sure before I buy some wheels. Thanks, in advance.
im looking to buy 19x8.5 and 19x11 for my 2000 c4 cab. From my understanding the offset for the rear is 63", what is the proper offset for the 19x8.5? Thanks!
