The last thing you want to do is break the law, especially when it's so easy to tell when you're driving around with studded tires past the date allowed by Idaho law. Everyone especially police officers hear the loud noise that comes with studded tires so make sure you don't have them on your vehicle past April 30th.

Here is the exact law as described by the state of Idaho.

Use of studded tires is only legal between October 1 and April 30, and people caught with them beyond that date could be fined $67. Studded tires have small metal cleats embedded in the rubber to provide traction on snow and ice.

Over this past weekend I did notice quite a few vehicles lined up at a tire shop close to my house and this could be a big reason why. Most tire shops will make quick work of swapping out studded tires for regular tires, but remember you're almost out of time.
