I was just thinking. When you run over a pebble the tire isn’t flexible enough (I think) to give in around the pebble (let’s say the size of a quarter.) However I’m guessing the rock doesn’t push the entire wheel up, since you don’t lose all traction at that corner. So what’s happening Oppos?

the tire gives. as it rolls over the pebble, the pressure increases until the pebble is ‘in’ the tire.
if its any bigger, then you might feel a slight bump

Ah, I didn’t think the tire would be that flexible.

Tire and spring act like 2 springs in series. tire gives some, spring gives some. How much is dependent on the spring constant of each.

I’m guessing I don’t want to know exactly how that works, but it sounds “legit.”

On top of what others have said about the tire giving, sometimes on certain types of roads under the right conditions, the pebble may be pressed slightly into the road. Think blacktop on a hot summer day.

Ah, brings me back to AP Physics 1 two years ago. Funny how it makes so much sense now but back then it didn’t at all.

The pebble launches into the air creating a slipspace rupture and allowing lizard people to come in and to rule the government.

The tire deforms. How is this not obvious?

I didn’t think they’d deform that much though.

Tire deformation is remarkable.

They don’t necessarily follow the exact profile of the pebble, more an approximation of it, i.e. with minimum radiuses.
Alternatively, depending on the pebble and how you hit it, it gets wedged in between a couple tread blocks and eventually punctures the tire.

I knew the sidewalls did, but I though the surface, so to speak, was much more rigid.

The tire deforms. Rubber is soft. Or, it gets caught in the tread pattern.

Forces on the tread actually deform the sidewall.
And, that’s also what really makes low rolling resistance tires - it’s not so much hard compounds and stiff sidewalls, as it is sidewalls that don’t lose a lot of energy in flexing (and therefore are supple).
