Different turning behavior after changing tires I recently replaced the both tyres on my tourism bycicle, going from a semi slick pair to a threaded pair, but keeping the same size, 700 x 28c.

The semi slick I had were these



while the new I have are these



Since then I have noticed a different behavior when I bend to turn.

While with the old tyres I had to "push in the curve" to keep the bike into the turn, with the new tyres I have to "pull out the curve" to keep the turn. In other words, with the old tyres the turning bike had the tendency to go back straight, while with the new tyres it has the tendency to close the turn.

Is this normal and will fade with some wear of the tyres, or do different tyres affect the bike dynamics?
You should read up on bicycle handling dynamic to understand how various elements influence how your bike behaves during cornering. You did not provide the actual sizes of each tyre, nor the pressure you use in them. My guesses to explain why your cornering has changed so much would be:


Your new tyres have a significantly bigger outer radius, hence affecting the trail of you bike.
Your new tyres run at lower pressure and are therefor flexing more when leaning in corners.
Your threaded tyre offer increased grip on the edges, while your slick have a reasonably constant grip regardless of leaning angle.
