Super Swamper TSL Thornbird Tire Review & Rating

The Super Swamper TSL Thornbird is a distinctive, aggressive-looking mud tire that is designed to provide the traction, handling and grip required by today’s off-roaders. Built for a wide range of jeep, SUV and light truck owners, the TSL Thornbird gives you the strength, durability and stability needed to travel through difficult terrains and still manages to give you the traction and handling needed on the street.

Sporting a three-stage sidewall lug design and a more aggressive tread design, the Super Swamper TSL Thornbird ensures that your rig has the traction required to go through rock, dirt, sand and other debris.

Super Swamper TSL Thornbird Tire Review

The tires’ narrower tread voids and siped lugs help with grip on wet pavement. Unfortunately, these same narrow voids inhibit traction in mud and deep snow. The treads quickly pack up and traction is lost.

Fiberglass belts beneath its tread and body plies constructed from polyester, combine together to offer a smoother, more comfortable ride, especially on the road. This is an area frequently mentioned in other driver reviews.

Super Swamper offers a range 15-17 inch sizes, with C and D load ranges available. A limited tread warranty is included.


  • Stylish, aggressive looks
  • Good traction, handling and grip on dry road surfaces
  • Performance off-road on everything other than mud and snow


  • Performs poorly in mud
  • Grip in deep snow and ice is nearly non-existent

Overall Thoughts

Everyone who sets their eyes on the Interco Super Swamper TSL Thornbird agree that it is an aggressive, eye-catching mud tire. However, owners of these tires have mixed feelings about almost every other aspect of this model.

It’s thick, deep tread and aggressive tread design delivers capable traction on most off-road terrain. We say most because when it comes to mud and snow, this tire falters. Narrow tread voids pack up and leave you trying to figure out how to continue moving forward. It’s disappointing for those looking for mud performance.

This model is really better suited for those looking for a street mud tire that features rugged good looks and dependable on-road drivability. It handles well on wet road surfaces for the most part due to the siped lugs. The ride is more comfortable and quiet than most mud tires.

Treadlife has been so-so as well. Used off-road, the tread lasts longer than most mud tires, but it wears down a little more quickly if you drive your rig on the road on a regular basis.

Overall, the Super Swamper TSL Thornbird is best described as a ‘Jack of all trades and a master of none’. Unless you are simply after looks and street performance, we feel there are much better options available for the money.

  1. I had a set of 35’s on a 1984 f150 I never had a single problem with the thornbird I would say the best tires I’ve ever had on a trail rig I shorten the frame and tossed the bed and doors I’ve had that truck in mud holes with mud and water chest deep setting in the driver seat and never one time had to be pulled out lived in central Kentucky maybe the clay mud was different from the other owners but I swear by them took me places I never thought a rig would or could go I’m not playing about the places they took me rail buggy drivers wouldn’t attempt to fallow along the ky river near Richmond ky

  2. Terrible tire!! Will never own another set..lack traction in mud, sidewalls crack in no time at all, tread life is awful, they wear very quickly and become difficult out to balance..they look great but perform awful!! Not made to be on the road much and pretty useless in mud..only good for show
