Tire Information
All 5 tires, including the spare tire, must meet or exceed the standards outlined below.
NOTE: Many newer vehicles are being produced with temporary, donut style spare tires, which do not meet our minimum safety requirements. Be sure to carefully, physically check your spare tire size for compliance before applying for an Oversand permit. "Donut" spare tires are prohibited.
Minimum Tire Size is 225 / 70 / R15
Tires with profile less than 70 are not recommended for oversand use at Cape Cod National Seashore. You may refer to the below chart for minimum requirements in obtaining an oversand permit with lower profile tires.
