I replaced a set of Goodyear F1 GS/D3's 6 months ago(tires were slicks at 18,500 miles; no kidding NO tread left) - went with F1 All Seasons because of some snow and cooler weather issues -

The all sesaons in warmer weather just DO NOT handle like the GS/D3's. The GS/D3's were great until about 12,000 miles then they became a little slick, and VERY loud. and below 40 degrees they were very slippery, until you drove on them for awhile.

So are all season's part of this?
