Help! traction control info?

the data we have all been waiting on ! Not as bad as I thought, at least when its cold and wet. If its cold and snow, you better have winter tires. Unless you don't like your car :headbonk:

looks like the data may already be out there. I will have to search a bit more later on. This is A/S vs. Winter on dry pavement. No hard numbers, but still interesting

Thanks for chasing down the videos, and particularly this one.

The description that they're giving for the all-season tire where the tread is no longer capable of conforming to the aggregate in the pavement is exactly what it feels like when a summer tire or all-season tire starts to come unstuck because of a too-low temperature. Feels like you're just floating along on the pavement, if that makes any sense.

I'm afraid that 'scientifically' would require the services of a driver skilled in coping with the behavior of cold tires just to get results repeatable enough to have any value. As such, you cannot expect the people having trouble with cold tires to be able to match it. Never mind that it's been a too-much-throttle issue here rather than a matter of braking.

Basically what I'm still trying to get across is that this is still more of a human problem than it is a car equipment shortcoming.

You think that my 50+ years of driving experience including cold weather and worse traction situations, autocross and HPDE (solo) driving experience, plus a basic understanding of vehicle dynamics and a predisposition to pay attention to things like what the current level of tire grip feels like means that I'm only speculating here?

As chance would have it, my oldest granddaughter (18 y/o with maybe a year of driving solo) just got her first object lesson in "cold tires" some time in the last couple of days. She managed to get a little unexpected wheelspin in her 160 HP Mazda 626. The kicker for you guys here is that she knew exactly why it had happened - maybe not with respect to what the ambient temperature was at the moment, just that she'd asked a little too much from her car's all-season tires. Learn from her experience if you'd rather, and know that I'm not making any of this up. It's too serious of a topic and the timing is just too good to pass up.

^^This. Driving is like being a pilot. You start with 2 buckets, an empty one of experience and a full one of luck. The goal is to fill the first one before you empty the second.
