If you mean to say "how fast is the side of the tire that is in contact with the pavement" then the correct answer would be "zero", assuming the tire is not skidding. But the vehicle speed would be 30 mph. Do you have anything more challenging?

when the tire comes in contact with the pavement the tire stops as the friction of both surfaces come in contact. Thus stopping that portion of the tire. it's speed would then become Zero until the rotation lifts the tire from the pavement. It's easier to understand if you look at the track of an excavator.

Law states that you can not declare a point in space and time!
It could be 120,000 MPH!!!
There is no right answer!
Trick ? even with the pavement as a reference!
If you stand still your going pretty fast. But you can't tell how fast!!!

Not at all. Your tire is moving in revolutions per minute. It's your car that is moving in miles per hour.
