Super Swamper Thornbird
Interco Super Swamper Thornbird Tires
The Thornbird was designed as a true "all-terrain" tire. The area of the tread that contacts the pavement was designed for a smooth, quiet ride. The sidelugs do not contact the pavement, but once off-road, they provide the extra bite needed for more aggressive wheelin'. The Thornbird's fiberglass/polyester construction keeps "cold morning thump" to a minimum and provides a decent street ride.
The Interco Super Swamper Thornbird is about as close as it gets to "two tires in one".
