My gut says the 19/20 Porsche Winter set is probably the one to go with - that will mean selling the Classic wheels. Alternatively, I could just find snows in the crazy OEM sizes and drive it. This is for Chicago. I'm curious what the group here thinks.

A) Sell the Classic, get the smaller wheels, they won't look as good but they will be better for winter
B) Find the right size snows for the 20/21 OEM wheels you have and go enjoy. That's why you got the tire and wheel insurance!

3) Less offset would be IDEAL since this car throws off SO much stuff
4) The difference between 305 and 295 is 0.4". You would not even be able to tell.

A) I LOVE the CC wheels!
B) I would consider the pre-packaged options.

I just bought a Hybrid Jeep, if you are interested in the set up, take a road trip to NJ for a pristine set with 350 miles on them, cost new $5200. I would sell them for $4,000 including the tire covers and the cradle to stack them.

Thanks, good to know that the tire rack ones work. I in the meantime also found a site - tpms.com that has OE and aftermarket Huf sensors. They state that they are pre programmed but after install they require a tpms "relearn". Is that the procedure you are referring to in the PCM for winter/summer selection?

I already have a set of Forgestar rims I custom ordered, haven't gotten the tires yet, as I am still waiting on the car to be delivered and still doing research. 🙂

Didn’t have any issues with fitment after researching extensively here I was comfortable with 295. Do your own due diligence of course. I’m in buffalo willing to ship if someone wants a deal on winter rubber. Also have weather techs.

I honestly don't know if they are 295 or 305, I would guess the 295, but I'm sure I'll find out Friday. Dealer is charging $1,800 installed for the set. Alpin somethings. The Continental Contacts were $1,600 installed and I felt better with the Alpins. I do believe due to low availability the Michelins may only be sold through the dealer due to an exclusive relationship Michelin has with Porsche on that tire in that size.

That can't be correct - I mean it could, but ... the tires alone are more than that! The rears cost $716 each (for 305).... alas, the 295s are significantly cheaper $550 each (going off TireRack here) Very interesting and yes the Continentals are much much cheaper $380 and Continentals do not appear to be made at 305... so yes, I think you are getting 295s...
That said... and porsche might get a better price... but just the tires alone from Discount tire (PA5) would run $2,000 before tax!

and I know Porsche dealers charge at least $100 a tire to mount and balance (at least they were for me)

So please report back after they take care of you - I'm hoping they made a big mistake and honor it! Cause that would be COOL.

I asked whether it would take some time (a couple months) or if they were expecting them, and he said they shouldn't take long. We could keep the appt. on the books and if they didn't arrive we could reschedule. When I called this week the set was completed in. I'll let you know what I find out.
