White knuckled the whole way as the car was not finding great traction, with 1 week old PS2's on it. As soon as I made it across the bridge, I pulled immediately into the first parking garage - the Queens Plaza self-park. It wasn't exactly a comforting feeling when I got out of the car and saw NYPD posters everywhere in the garage warning about car theft. The train got me home safe and sound that night. The next morning, with fingers crossed, I found my car still in the garage exactly how I left it...

If there's ever a chance of snow, I will definitely not take the Porsche unless I get snow tires for it- I've certainly learned my lesson...
so did you order your snow tires? i am going to order mine today.. hmm.. your story sounds pretty close to mine, my speed was a little faster i was doing 15mph in second, and i lost control of it like 3 times, the last time, i was just praying to get off of the highway, i will hopefully let everyone know later today, how it is resolved.
thanks again
good luck my friend, we are in the same boat

Winter tires only come in 295/30/19s.

I did some research and found that the 295s are 25.96" tall compared to 26.2 for the 305s.

The 295s spin at 801.2 revs per mile compared to 793.8 for the 305s.

The 295s are 11.61 inches wide vs 12.00 for the 305s.

My question is, are the 295s close enough in size that this will not affect the AWD system and possibly burn out a differential?

One other option I thought of might be to change the fronts to 225/35/19s and the back to 295/30/19s to try to keep the ratio close to the stock 235/35/19s and 305/30/19s.

You know, it would be much easier if one tire company would step up and make an all-season in 305/30/19s.

Tires I have researched in 295/30/19s that seem to be good are:

Toyo Proxes 4, Bridgetone Pole Positions All-season, and the Contis.

I would recommend getting a set of 18" takeoffs (wheel enhancement?) and any of the speed rated snow tires. Having 18" wheels means more sidewall for winter potholes, snow drifts, curbs, etc. Plus 18" tires are much cheaper. Save those turbo 19's for the Spring.

No question about snow tires. Call tire rack - the prices are the best. Where else can you get a winter insurance policy for $1100.

The 19" continental 810S tires have worked great for me this winter. I'm using my 997 GT3 as my every day driver in the winter without any problems or complaints. The tires are great on the road regardless of snow or ice. The snow tires handle great and are not "squirmy" like other snow tires. 295 in rear is correct size. Again, zero problems and don't forget, I don't have AWD or any stability control - just good old weight over the rear end - that's all you need. You guys in the 4S cars are cheating.

The 295/30 19 is the correct winter tire for your car. We do have winter tire and wheel packages in stock.

No problems at all with different radius. Infact, these Contis are recommended ( developed?) by Porsche, so they will work great under Your 4WD

Winter shoes a must

While not extensively used across the States relative to Europe (with some small exceptions with the Snowbelt statres), winter tires are a must, regardless if you drive in snow, as long as you drive in the winter. I have had winter shoes on all my cars and it has been a well worth investment. As stated before, the compound of the summer rubber is meant to be used in operating temperatures exceeding 45 degrees or so, otherwise the rubber starts feeling like plastic...

I plowed through the latest NorEaster on my way to VT a few weeks ago in my M5 with ease, seeing large SUVs ala Range Rover Sport S/C or STR8s being trapped in ditches. Amazing how most people that buy these cars with the 20+ inch sport rims think just beacuse it is an AWD SUV it will get you out of trouble. Quite on the contrary, you can be the best track and field star, but with the wrong shoes you'll go no where...

Tirerack has been there for me for all my needs over the years. I've been looking at available options for the C4S, and it seems there is only 1 tire that is recommended for the stock fitment. I would however go the route of downgradnig one wheel size (as long as the specific rim will clear the caliper) in exchange for thicker profile. The investment will ay off in 2 yrs, with less wear on your stock rims (in terms of salt, and frequent mounting), and safer journeys. Def a no brainer...
