What's the difference?

between an LT235/85R16 and a LT265/75R16? They're the same diameter, correct? Is the width different? Why would you use one size over the other? I'm interested in a good towing tire. Currently, have 285/75 16. I had been thinking about going with the new Toyo 255/85R16 but that tire appears to be slightly taller than my current BFGs. With the truck's 3.73 gearing, I would be concerned that I'm lowering the gear ratio too much. I want this tranny to last a long time and I tow a fairly heavy TT.

Need more gear? 245's are shorter - 235's and 265's are closer than the speedo accuracy, the 265's give an extra inch of tread to lower the psi on the ground, they are 1/2 in closer to the frame on the inside.
