Knobbies also squirm on paved corners and give you less traction than
slicks. There are rare road conditions where knobbies are superior,
like when the road is so crappy you are essentially trail riding -- or
not making contact with the pavement because of snow or leaf pack.
But most of the time, your tire makes contact with the pavement, and a
slick will give better traction in that situation. I ride 28mm tires
during the long rainy season. Even though the super tough tires (like
my current Bontrager "Hard Case") are good to have because they are
flat resistant, they suck traction-wise in part because of the tread
compound but also because they are so stiff and non-compliant. I
prefer a soft compound, compliant tire for riding in the rain,
although that may mean fixing more flats in the rain. As for fresh
leaves (and not hard packed leaves stuck to the pavement), you're
screwed. Nothing will give you traction because even if your tire
sticks to the leaves, the leaves are not sticking to the pavement.
