A tyre question with a difference

Thanks for the replies all.
I think I'll do some experimenting dropping the 235's pressures & applying it to the proposed 255's. The taller tyres will give me a bit more diff clearance, which is becoming more critical on some tracks in Vic.
Whilst dropping pressures is a pain, it is the quickest answer. When I get home from a trip I just want to remove the rooftop camper, (it gets suspended under the carport) stash the Landie in the garage & sort it all out another day.
This is probably what made me think about 255"s
