going up a size?

going up a size?
I want to get a more aggressive looking tire, but I want to keep the "E" load range but cant find many in the stock size. If I go up to 285 70 17, what are any negatives? I do alot of towing and some fairly heavy towing. Will going up one size be noticable when towing? Will mileage suffer? Anything else I should be concerned with?

Look at the manufact load rating for the tire you have in mind. Just because it is listed with an "E" does not mean it will always handle more weight than brand X with a "D".
I really doubt your CTD will be radically affected in terms of perf and milage going from a 265 70 R17 to a 285 70 17.

The reason I ask is because the guy at the tire shop told me that if I go up a size, I would essentially go from 3.73's to like 3.55's(gear ratios). He said I would lose "take-off" power when towing and cause the tranny undue stress..
Anything to what this guy is saying?????

Well he is correct about the effective gear ratio changing. That sounds about right, but don't have my formula here.
As far as losing take off power, yes because of the gear ration change, but I doubt with the Cummins that you will really notice it that much if any.

There are plenty of people running 33's-35's all day everyday, and it's not killing the tranny's. I have run 33's for 50k miles on two trucks without any issues.

Yeah most tire guys (no offense) like to make there job seem more influintial than it is. I dont even ask them anymore cause they tell you all kinds of crap thats only mildly true. I once had a guy tell me that he has seen wheels break off the axle from not being the manufactures recomended size. What ever buddy, must've beem like 48" tires on a Tracker or something.
