At what temp should we not drive this winter?

[rdrfronty]

I know many of you guys up north have the painful task of having to put your 1LE's to rest over the winter. I really feel for you guys there. But what about us in a more moderate region?
Exactly what teperature would you guys suggest NOT to drive in?
First thing is my 1LE is primarily a weekend driver. And it's driven mostly in rural areas. And the areas I drive never have salt put down for winter conditions.
I'm not worried about loss of traction. I've already driven my car in 39F temp range a couple times and it has MUCH better traction and road holding ability then my previous 2 vehicles. Which were both modded trucks. Light rearends and high horsepower makes for "butt-pucker" driving at times. So I know to drive slow and careful when conditions demand it. And temps below 50F I drive very careful around curves and when accelerating in the 1LE.
So my main concern is temperatures that might damage the tires. I am aware of the 20F level that they say DO NOT drive at. Possible damage is very possible at that point and colder. But what about temps below 32F if it's not persay driven when its still that cold. Meaning if it gets down to 30F at night, but the temp gets up to 40F around noon when I need to take a drive?
Here in the rural/country area where I have my 1LE on weekends it freezes perhaps 10-15 weekends a year. Perhaps 2-3 of those weekends might approach the 20F area. I'd also estimate 14 of those 15 weekends it gets above freezing by noon time. It's VERY rare we stay below freezing.
.
So does this general plan make sense? -
1-Any time the forcast says it will approach 20-25F - keep the 1LE garaged.
2-Any time the forcast says it it will freeze AND and stay close to 32F during the day - keep the 1LE garaged.
3-anytime the forcast estimates nights to get in the 30-34F range, but warm up to 40F or before car would be driven - ok to drive the 1LE that weekend (with caution of course)
4-anytime ice or snow is in the forcast (which is very rare) - keep the 1LE garaged.
.
These questions might seem silly to some, but for me, driving my 1LE is my MAIN source of entertainment at this point in my life. I live and work M-F in the city, driving a little Kia ecobox to do so. But weekends I take the 1LE up to a country house I own. Nice fresh air, lots of trees, AND twisty country roads to drive on. Weekends at the country house and driving my 1LE is what makes my work week bearable. I DREAD the coming weekends that I wont be able to drive my baby.
Oh, lastly - I CANNOT purchase winter tires & wheels at this time. That is perhaps the plan a couple winters down the road, but my current budget doesn't permit the $2500 it would require for a "toy" expenditure this winter.
Suggestions and opinions on the "general plan" above are welcome.

Like you mentioned, there is a potential for damage in colder temps.
If you look around there's a few threads where people have experienced their tires cracking in sub-zero temps, even when their car is stored, though it seems to be sporadic (e.g. http://www.camaro5.com/forums/showthread.php?t=335966)

Seeing as you live in Texas though, your plan seems fine as I'm sure asphalt / concrete warms up pretty quickly on the nights temperatures creep below freezing.

If you drive responsibly obviously nothing will happen, just be aware of cold rain / wet surfaces as those tires get rock hard below 40, and you risk skating around, even at low speeds

Tire Storage
It is recommended for these tires to be stored indoors at temperatures above 20 deg F (-7 deg C) when not in use. If the tires have been subject to 20 deg F (-7 deg C) or less, let them warm up in a heated space to at least 40 deg F for 24 hours or more before installation or driving the vehicle. Inflate the tires only after they have been warmed above 40 deg F (5 deg C). Do not place tires near heaters or heating devices used to warm the room where the tires are stored. Do not apply heat or blow heated air directly on the tires. Always inspect tires before use after storage periods.

I chose to buy a set of Michelins, and I enjoy my 1LE year round. Plus, I don't feel like I've given up a thing on handling or traction.

Well your plan sounds solid when to drive the 1le or not. My suggestion is we all know how the weather can be forcasted and then it's not so accurate the day of. As you mentioned that buying a set of winter tires would be considered. I would seriously look at that option. I know factory reproductions have great deals on rims and tires and it be worth that cost. The worst thing to happen is running the summer sport tires going back on a 30 something degree day after your visit to your weekend home/trip and havong to buy a set of tires anyways.

I keep the car in the garage after the first time they salt the roads until spring time when its washed away. Even if it warms up a little there still is all that nasty shit on the roads and gets kicked up onto/ under the car

I drive mine reguardless of the temperature. But I wont take it out in the slop, and salt. I too swapped my tires for Nittos, just for this reason.

Now if I could find a snow plow mounting kit, It would be perfect. Winter sucks!

Mine doesn't come out if the high is under 40 because of the tires. I'll bring it out if it's in the 30's in the morning but will warm to over 40.

That, and if there's salt and sand on the road, it doesn't come out until that's cleared off. Starting Tuesday, I think we're done with anything over 40 except for the rare warm days, so it's getting prepped to store Monday/Tuesday.

I live in Maryland and right no wit is my daily driver. I have michelin as3 all seasons in the garage waiting to be installed. I also have a supercharger on the way. I plan on driving it as long as there is no ice out. I will avoid the slop but hell, I might have to take it out if its dry and a little salty that is what the under spray car wash is for, right?

In your case, I think what you said makes perfect sense. But i would suggest looking into the as3s when it is time to get some new tires.

Thanks for the input guys. I'll just with my plan this winter and then hopefully get some extra winter tires/wheels in the next year or two.
