Could also be a bearing, but its less probable and you'll know conclusively when it will make a strong woo-woo noise.

Sounds like normal ABS behavior. You braked harder than the grip allowed and ABS made a clean stop for you.

I strongly advice that you get used to the maximum brake capacity of your car in a controlled environment, accounting for a variety of weather, and train yourself at proper braking technique before trying to drive hard on open roads.

Now, if you are an experienced driver, and you think that your braking shouldn't have triggered ABS, there are a variety of suspension condition that can make handling so bad that ABS kick in very early. If you think so, have your suspension system (tires, shocks, springs etc) inspected. Also remember that summer tires have little grip in cold weather, that can lead to surprisingly bad handling.
Thanks I got the tires this year and still have plenty of tread on them. It could possibly be the balancing because the weights are glued on the inside of the wheel not clipped on the lip
