Shorty - REAL 7.50s are 32-32.5" in an offroad pattern.
The reason that larger tyres make it more likely to break things is (IMHO) related to torque rather than weight.

Eldorado do them. Pat
depending on how your driving IVe regularly been known to go down to 8 psi which at one stage was what I was running on the sundown trip and Ive been known to goto 4psi to help out with recovery work.
the general consesnsus for tubed or tubeless tyres is about 15psi
In "Rustic" the Defe I have 2 sets.
One set is on standard Defender rims with Pirelli Scorpion 750R 16 tyres
The second set are Maxxis Buck Shot 235-85-16 on RR alloy rims.
I like both sets but for long trips I prefer the tubeless Maxxis.
The Pirelli tyres are less noise but not have the grip of the Maxxis
The Maxxis are in Bob Jane for about $ 200.00 each
Mark, the best solution is get 2 sets ;)
