Now looking at it I don't see too much difference
in it either, but their site said:
The Super Swamper LTBs are in the same basic
Three Stage Lug design as the famous Super
Swamper TSL’s but a little more aggressive. The
large lug is offset more to the outside which gives
the tire superb traction. It is in bias ply construction
which allows for the more aggressive lugs and very
strong sidewalls to better resist the rigors of hard off-roading.
The bias construction reduces the chances
of sidewall splitting when run off road at low air
pressure. There are seven sizes available….sizes
which are not available in the regular TSL line.
