Ive been driving mine with the stock tires. It does slip a lot and I try to avoid driving it whenever there is snow on the ground. Fortuneatly I have access to a 4x4 for those days. It does go, just not as confidently as a 4x4.

 

I also put blizzaks on. They make a world of difference. You might not need any wieght at all. I used the stock size as well with the stock rims (which will ultimately be my winter rims). The tires are a bit pricey, but are the best out there.

 

I've got Dunlop M3's on my GT and so far so good. Monday creeped to work at 6am in an ice storm. Had a little slipping and sliding but made it there and back fine. Didn't go over 20 mph in the morning though, got it up to about 30 that afternoon coming home.

Last night coming home with about 2 inches of snow on the ground she was fine. I have a 10 percent grade hill going to my neighborhood which was snow covered and I took it at 20mph the whole way. no slipping at all.

The key to snow tires IMO is they let you get to where you're going, as long as you're not in a hurry.

The M3's also do ok on the dry pavement. I won't be taking any serious contenders until spring and I switch them out, but i've had fun even with the snow tires on, if you know what I mean.

 

All you need to know how to do is counter steer and you can handle any car in the snow. My 2002 GT was all over the place but I knew how the car would handle at any speed and condition because I practiced with it.

I would suggest taking your car to a snowy parking lot and do some doughnuts and turns to get a feel for how it will respond.

I will say though that the 05 is much improved over my past Stang. The traction control is more effective.

I had to drive to work today in about 2" of snow. Nothing scary but there was some freezing rain under the snow that we got the night before.

I am still looking for a winter car though so I can keep my baby in the garage and avoid it all together.

 

Well, I have an '05 GT Stang and it's not a very good car for the snow. The Stang has a wheel rear drive. Which means your back will be all over the place. You know what I mean? Aside from that, it is a great car. I love my Stang!

 

Welcome !
Actually, I have been driving rear drive through winter for decades.
So it kind of bothers me when people say it shouldn't be done.
I know some guys from up here that have run 2005+ GTs all winter long up here in the snow.
If you have good tires and a little weight over the rear wheels you can do quite well.
My little 2WD Ranger goes great in the snow.
I have aggressive off-road tires and 300lbs of sand in the back.
I have no trouble keeping up with or out accelerating from a stop those little FWD cars they always tell me are great in the snow.

 

I have drivin my 06 several winters on the stock a/s pirelli tires no problems and we have had a few good snow falls here around chicago. Just need to leave a little more room between you and the other guy. My 2k stang was pretty bad but the 06 is worlds better than the 2000 in the snow. No weight in the trunk, the car is almost a 50/50 balance from front to rear.

 

I agree with glenn . .. I spent 2 or 3 Michigan winters with an 05 GT . . . . . with no sand . . . . . . the traction control and the 50/50 balance will allow you to pass thru LEVEL, PLOWED, slushy roads . . . . . is it an SUV??? NO . . . . . now my 05 S197 is enjoying salt free, sunny California roads year round!
