1. 40's is not sunny bro. that's pretty ****ing cold. Tires don't stick when its cold
2. It's brand new tires, compound is not ready for sticky wiky.
3. You sound like you take turns pretty hard.. 90mph??? da ****. stop driving so fast and make my insurance go up. Done.

PS: yea you are lucky to not to own motorcycle. you will high side like no other.

 

The company i used to work for, NTB, allowed 30 days to return and get a new set put on (you pay the difference of course). You could try to get a new set...

A/S and summer tires are completely different animals...it all comes down to void-to-rubber ratio and compound differences. The more voids in the tread than rubber contacting the ground through the contact patch allows for more water evacuation (since there are crevices for the water to go into). Summer tires have less voids to have more rubber contact the ground, hence better traction. Summer tires also use different compounds in different places for better handling (like michelin tires), this allows them to compromise between wet and dry weather traction. Some summer tires (like Advan Neovas cannot be run or even STORED below 14 degrees F if i remember right) because of the damage to the compounds when frozen.

Hope this helps

 

Do you know what a differential is? Also, it's a LIMITED slip differential. If you are slipping in 46 degree weather, I'm not all that surprised, especially considering you switched from summer to all season, and they are also new.

 

New or tires that haven't been used for months have a layer that needs to be burned or driven off. Ever use a pencil that develops a plastic-like coating over the rubber eraser when you don't use it? Same concept with tires. You just have to wear it off.

 

While the mold release film is contributing to the traction issues slightly, the fact that the tires are all season is the KEY difference. if you want your traction back you will need the correct tires

 

you realize that you're on the street and don't drive like a lunatic

 

I got close to 30k miles out of a set. As with ANY tire, it's all about your alignment specs, and pressure

I currently have 10k miles on my RE050A's, zero issues and they are not wearing substantially at all.

 

True about alignment and pressure...but your right foot is a gigantic factor as well...roasted my stock michelin PS1's (yes...they were the stock tire) in 11k miles. Excellent tires BTW, but the treadlife left something to be desired. Came off the car at 4/32 worn even across

GForce KDW TT's all the way now. Loud, agressive, but they stick like hell

Meant to edit my post above too...tire innards are extremely important as well...segmented construction vs 'clam shell', bias ply vs radial, use of nylon to prevent distortion...oddly enough, they are facinating objects which no one evers pays enough attention to.

 

Honestly, I totally put it to the East Coast winter man, and that's the only reason it belongs in these regional forums.

The gradient in temperature is ridiculous out here, and does wonders for our tires... Every time it gets warmer/cooler, you go driving, etc., you probably lose a little pressure. On new tires, that's weird.

For me, I've noticed my car isn't as sticky in the corners, but I attribute it totally to the winter and my tires having probably a bit less pressure than they should. It's most likely nothing to worry about. Just pray that groundhog does the right **** in February so the roads can become ours again.

 

Testify Brother! Amen!

 

Those tires aren't for track so they will not respond as well. Also check your tire pressure. If they are too inflated that could also cause some slippage. you want to be between 35-40 max. I would say get some winter beater wheels like 17s and get some summer tires for your 19s. GL

 

really? its not the opening scene of 2fast2furious everytime you get in your car man. who races around turns on the street? thats asking for something bad to happen.

go to an open parking lot and take traction control off. spin your car out alot and try and correct the oversteer until you get a feel for how much throttle response and steering control you need at certain speeds/angles to prevent you from losing it and sliding into a curb or ditch when it happens on accident on the street.

i test my car all the time with how much of an angle i can get on it without losing it. ive been doing that sort of thing in parking lots since i was little and had my first car and now being older it has saved me a few times when the Z just lets its *** out in the rain (even with traction on)

so before you keep racing through turns i think you need to learn how to control your car better first, otherwise you would have never asked that question.

 

TireRack has a section on breaking in winter tires.* read it, you'll see why.*

Do you hit the NOS switch in the corners?

 

I have these on right now...they are horrible in this weather IMO.
