Hi mate,
I lead a trip up to wesburn sunday 17th may, it was very wet and slippery, depending the tracks you wish to go I would suggest very good muddies. there was also some tracks that had some deep ruts, all depends on what tracks you are looking to do.
Britannia range trk muddies mabe winch,
Cemetery trk deep rutts 33s and whinch,
Burns rd at the lest 33s lockers whinch,
Ellis trk all the above and time
Thats the tracks ive done on 35s simex. It all depends on you and your 4wds capabilaity and accsories.
Hope that helps
good luck
