Okay folks - after reading a lot over the last several months and contributing where I can, I have a question of my own that I hope you folks can help me with.
I have a 2004 F350 crew cab 4WD Powerstroke. It comes with 3.73 differentials. It also came with stock (wimpy looking) 265/75R16 tires (Pirelli Scorpian STRA). Actually the tires seem pretty nice, but are obviously road tires and just "look" small on the truck. I am looking at going to 295/75R16 - either the load range D BFG All Terrains which have the same load capacity as the 265 load range E or to the Bridgestone Revo's (cause they are great tires).
My question is this: Changing the tire diameter effectively changes my differential ratios from 3.73 to 3.55 Does anyone know how to determine how much this is going to change my towing capacity? Is there some formula out there or such? I don't want to go through the trouble and expence of change the differential ratios.
Thanks for your ideas.
Don
