Anyone know what the difference in Swampers TSL, TSL SX, and LTB's are?

And are all swampers heavy? The Trxus is HEAVY, would put extra strain to move and then fukin heaps more to stop!

TSLs are either the normal bias plys or the Radial ones (SSR or Radial). All are proven, and the bias plys have set the bench-mark time and time again.
SXs are the same as the bias plys with steel belts in them, tighten tread design and nice sidewall tread for rocks/mud traction
LTBs are a recent derivative with a cheapish mexican-made compound, they have nice small sizes, and a longer large lug.
That's all I can help with.
