try getting a land rover, get further then with your tyres :lol:
on a seroius note,
take the pressure down to 18psi
u wont nock them off rims i ran 31 inch grizzlys at 16psi at comps without them coming off :roll:
maybe i was lucky tho :lol:
anyhows air them down, but get a decent guage, have a look on devon4x4's website for the nice new arb one that come out, mines on order yyyay :lol:
even my simex stuggle and dig down some times just depends what its like on the day :roll:
but id suggest a thin tyre to dig down to firmer ground underneath not a wide tire that is going to float and not provide much traction,
IMO, for your use greenlanes ect id say save up abit and get some bfg muds
ino its the same patter, but they are way way better also they got some nice lugs on the side, so if you air them down you got abit of extra tread then
but hey thats my opinion, do what the hell u like :lol: :lol:
255/85/16s are a damn good size
but they are virtualy 33 inch so i doubt youll be able to fit them under the arches :?
so otherwise same size as you got now or 235/85/16's
