New tires slipping and sliding when braking in 1/2" snow?

    I bought BF Goodrich Traction T/A's (H-rating) last month.

    today, it's snowing. the ground only had like 1/2" of snow. i was going about 30mph in a 45mph zone, and left plenty of space between me and the car in front.

    he hit his brakes, and i hit mine softly since there was lots of space. i noticed i wasnt slowing down as normal. so i pressed on the brakes harder (not ABS), and my car started to turn sideways about 10 degrees.

    Traction T/A's have AA traction rating.

    Is it normal for new tires with a good traction rating to slip and slide when braking in light snow? If so, WHY?

    The UTQG ratings are not particularly good at showing real world performance. In fact, almost any modern tire will rate A or AA in traction. I pulled an explanation from the UTQG website:

    So that traction rating really doesn't apply in many real-world scenarios. All it does is measure how much friction the tire generates on a wet road when it's locked up. Not very helpful for figuring out things like snow traction.

    yes, it is normal and perhaps the rating causes a false sense of security. A light shower of rain can lead to loss of traction perhaps worse than what you noticed with 1/2" of snow (but perhaps not with those tires). The real world is a bitch :p

    For snow and ice you really want to look for the M+S (mud and snow) rating, which any all-season tire should have. According to this, the Traction T/A H is an all-season tire, so shouldn't be that bad. A dedicated snow tire would still be much better.

    According to NHTSA
    http://www.nhtsa.dot.gov/cars/...v/evaluate/807805.html

    In other word, don't take rating too seriously specially 4 season tires.
    Besides the obvious, tires's "fresh coating" require 300~1000 miles to wear off before reach its ultimate traction. It is also not hard to determine what "characteristic" your tire have by looking at the tread design. (let's disregard the compound rating, sidewall strength and etc for now)

    Take your tire's tread design for example.
    It has uni-directional design. V-pattern is great for anti-hydroplanning. But we all know it takes snow to stop in the snow. If it propell the snow off your tires, w/ multi-Channel then it might not be such a great snow performer. Notice great snow tires always has multi-uneven-micro grove on their design? So they can "HOLD" snow on tires.

    Your tires looks like it should perform well in CITY's dry and rain condition. However, it might be bit noiser since the gap between each block is wider.

    Check the snow rating on tirerack.com. They could just suck in the snow.

    Also don't brake like that in the snow, pump your brakes so you don't lose traction.

    If you want the technical term, those micro grooves are called "sipes". :) And yes they do help for the snow. If you look real close, all-season tires have them, just maybe not as many as a snow tire. Snow tires have other tricks like a micro-porous compound to wick away water.

    there is a break in period for tires

    think it's 500 miles

    apply the brakes slowly instead of slamming on them

    take back my previous statement about pumping ABS breaks realized the op said he didn't have ABS brakes.

    shouldn't have to do that if you have a modern car.

    OP specifically stated he did NOT have ABS. I'm trying to help him from losing control of his car.

    How often have you driven in the snow before? I mean, you should know it's not normal if you've been able to stop with other tires before, no?

    Pumping the brakes isn't as good as braking steadily near the edge of traction, and easing up and reapplying if you LOSE traction...but that takes a lot more concentration.

    Those are all season tires. If you get snow you really should have a second set of wheels with snow tires.

    As long as you drive slow and cautiously it doesn't matter what kind of tire you have :)

    LOL!

    Try a high performance summer tire on snow. You'll be lucky to even move.

    Traction ratings are for *edit* WET performance compared to other's in it's same class.

    You need a M+S or pure snow tire for any kind of traction in white stuff.
