i agree, the torque and fuel consumption are altered slightly but its worth it. You also got to think about the extra strain on the transmition. You guys with the 33" upwards tyres must be crossing fingers lol. However my 265 tyres are attached to steel wheels that are heavier than the oem alloys so my figures will be different.

Theres a guy in the gallery with 285 75 16 tyres on standard rims. check it out. Just type 285 into the gallery search.
