Special Purpose Vehicle 4WD: Typical Tire Size
The EPA Special Purpose Vehicle 4WD segment typically comes equipped with original equipment tire sizes around 255/75R17, mounted on 17-inch wheels. However, vehicles in this class commonly range from 16-inch to 18-inch wheel diameters depending on the specific model and configuration. This size represents a balance between on-road comfort, off-road capability, and load-carrying capacity typical of modern four-wheel-drive utility vehicles.
Tire sizes within this segment vary based on trim level and available wheel packages. Higher trim levels or specialty packages may offer larger diameter wheels paired with lower-profile tires, while base models often use more traditional proportions. Load index and speed rating also differ across configurations to match each vehicle's performance requirements. Vehicle owners should always verify their specific tire fitment by consulting the tire and loading information placard located on the driver's door jamb, as recommendations vary by model year and individual vehicle specifications.
