What minimum tire tread depth does Florida require on your vehicle's tires?
-
A.
1/32 of an inch
-
B.
3/32 of an inch Correct
-
C.
2/32 of an inch
-
D.
4/32 of an inch
The answer is "3/32 of an inch"
The equipment standards set Florida's minimum tread at 3/32 of an inch, with no worn spots showing the ply. Choice C, 2/32, is the penny-test benchmark drivers hear at tire shops; Florida sets its floor one thirty-second higher.
The traps in the wrong answers
A. 1/32 of an inch
The Florida minimum is 3/32, not 1/32 of an inch. This answer picks the smallest fraction offered on the assumption tread rules are lenient.
C. 2/32 of an inch
Two-thirty-seconds is a common penny-test benchmark, but Florida's handbook states a 3/32-inch minimum. This answer treats the penny test used at tire shops as if it set the state's legal floor.
D. 4/32 of an inch
Four-thirty-seconds is a common tire-shop replacement recommendation, not the legal minimum. This answer rounds up to a shop's replacement guidance on the assumption the state's floor matches wet-traction advice.
