Outer Limits 4x4 Board

ive got a set of coopers st 265/75 16 off my cruiser
and want to know will these tyres go on a standard 04 d/cab hilux
ive got split rims atm ,and know id need rims to suit them too
will these bigger tyres chew more fuel and be better or worse for towing a trailer and quad ????

I'm getting some fitted tomorrow, I'll let you know!

Come to think of it I think I settled on the 255 to avoid any chance of rubbing, let you know tomorrow..
