Any point in swapping out 245/75/16 Wranglers for BFG 235/85/16 TKO?? Bit larger diameter, stiffer sidewall. Would it improve fuel economy or handling? I can live with the spedo off a bit.... my ...

I swapped out 245/17R for 285/17R tires to get an extra 1100 lbs. of load capacity at the rear. New tires are 1 inch larger in diameter when the truck is unloaded and this results in a 4% error with the odometer/speedometer reading or its being off by about 2 MPH or 1/2 MPG - both lower than actual.
With a 3000 lb. camper load in the bed the tires squat and my odometer and speedometer readings are more accurate with the new tires than with the factory supplied ones. In effect there is little or no change in the overall gearing for the truck.
It is odd how people can ignore the problems with tall 3.55 or 3.33 gears but worry about a 4% change in tire diameter. There is a 25% difference in performance between 3.73 and 4.10 gears in towing capacity and this is significant.
