I run the 8&10 with 225/40/18 and 265/35/18 using Firestone Winterforce.
Leading evidence: 'Run 8&10' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Recommend tire size, rim size, and rim offset' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

first, in the tires, rims, tracks section of my 03 c4s manual the recommended tire size, rim size, and rim offset.

Always run the narrowest wheel you can get away with during the winter.
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.

Hey Guys,
ordered a set of 265/35/18 blizzaks for the rear and 225/40/18 for the front.
tire shop wants me on 18x9.5 for rear and 18x8.5 front.
Is anyone running this tire size/wheel size combo?
Looked on tirerack and they say an 18x10 for the rear will work.
Help please as i watch the snow pile up outside....tomorrow will be daunting...
That should be fine, I believe 9.5 wide is the ideal width, but cant confirm without looking at my book. going with a 10 will stretch out the tire a little making the rear diameter slightly less that what the tire is rated for, I do it with all my rear tires.
sorry just checked optimal width is 9-10.5 inches the tread width is 9.5 inches which is why the tire shop probably said to go with a 9.5 wide wheel, so you will have a bit of width. you can stretch tires pretty far and this is not anywhere near the limits. I stretched a 195 tire on a 10 inch wheel for a vdub a while ago that was about a far as i was able to ever get a bead sat, though it isn't what I would call safe, and would never recommend it to anyone
Narrower rims (17-in diameter, width of 7-in front, 8.5-in rear as Porsche recommends) would be more efficient in snow.
Anything wider would have more of a tendency to plow or float over snow rather than grip it or track it properly.
In winter conditions, you want more functionality even if appearance suffers. In the cold, nobody really cares enough to pay attention to appearance, except perhaps the self-conscious PCar owner.
This' the season for getting home safely.
My 2 Cdn cents worth! Cheers!

hello eveyone,
here is what i was able to find. first, in the tires, rims, tracks section of my 03 c4s manual the recommended tire size, rim size, and rim offset. second is regarding the choice of n rated tires.
martin, as far as your 00 c2 - my manual (which is for 03 model) says you can use 17 rims.
i use 225/40 r 18 on 8 x 18 rims. rear is 265/35 r 18 on 11 (yes 11) x 18 rims. no problems with the rears.
hope this helps
Always run the narrowest wheel you can get away with during the winter. Otherwise you're sliding all over the place. High quality dedicated snow tires are the absolute way to go! (I have a set of Alpins for my other rear drive winter car and they never fail me!)
