Was using Simex Centipede MT in 31/10.5/15 sounded like a truck, vague handling, handled everything.
Went back to a 235/75/15 Maxxis 751. Handle a lot better, quieter, still handles everything that the Simex use to do, and nicer to drive on the black stuff.
Drop to 15psi in the sand and they go anywhere.
I would recommend these to anyone.
