Influence of tire breadth on cornering Due to a bike replacement, I recently started using 700x40C tires, after several years of using 700x35C or 700x28C.



Whenever I corner, I have the impression the bike is behaving differently than what I was used to. Especially in fast/narrow corners (90 to 120 degrees turn), I feel like a squeaking sound coming from the engaged side of the tire (think like when one rubs a rubber shoe on the floor), while with the previous bike, mounting narrower tires, I never felt the same.

How does the tire breadth influence cornering of a bike?

Additional info:


tires inflated at the high end of their suggested pressure range (75 psi)

threaded tire
rigid fork
paved roads, dry and not dusty
approach speed 15 to 20 km/h
My guess is the squeak:


Does not happen on all road surfaces
Occurs while turning due to friction between the tire and the road generated during a turn.
Is not related to tire width or frame geometry


Going out on a limb...
The squeak will go away as the "shine" is worn off your tires.
You might be able to change or entirely get rid of the sound by changing tire pressure.

In the original post nothing is mentioned concerning reduced traction or ride issues.
Tire pressure should be adjusted to gain the best traction and ride - not to get rid of this sound.
