Tire slip angle diagram, wet vs. dry
#1

Does someone have a link to a tire slip angle diagram, so I can see how it changes from dry to wet?
I want to understand why tires behave the way they do in the wet (e.g., cornering force past the peak at very high slip angles, is a larger % down from the peak, in the wet vs. dry, or the dropoff is more abrupt).
Cheers.

I was curious about street tires.
Basically I want to understand why a car behaves like this in the wet:

The diagram in your first post doesn't make sense wrt what I think it should be.
Upper left hand diagram in 2nd post does:
- wet grip peaks early then drops
Have you seen any more diagrams? The tire book by Haney is good but doesn't show any comparison of wet vs dry for a hi perf street tire.
The paper you linked was pretty interesting BTW.

So do you agree or disagree that they agree?

But it does so too, in the first diagram - No?
The main difference is, IMO, that the second diagram, does not show the slip angle range past peak value for the dry road.
Anyways, it's a complex matter, and I'm not the expert for it.
There are many factors coming into play here, and all of them have a effect on the final outcome.
Not sure, how deep you want/need to dive into the subject, but you may find some "food for thought"
Here CAUTION !!! it's an 850 page pdf file, so may take a while to load

good luck
Thanks. I looked at all the diagrams and didn't see a slip angle diagram showing wet vs dry.
