    Should be the same width. 75 tire is a little taller. Here is a great website for comparables. Tire Size Calculator - tire & wheel plus sizing

    I've had 265/75/16's on mine for a while. This size really fills out the wheel well nicely. They don't rub either.

    Your actions speak so loudly, I can't hear what you're saying.

    265/75 are probably what you want, they are taller by like an inch over 265/70.

    Just put a BFG AT KO on my 2006 DC. It's a 265/75/16. I test fit the 275/70/16 and it rubbed. I have a 2.5" lift in the front and a 1.5" block in the rear. I really am happy with the 265/75/16....it's actually a little taller than the 275/70/16. By the way, the first number (265 means that the width of the tire is 265mm). The second number is the percent of sidewall and the third is the size of the rim. Go with a 265/75/16, you'll be glad you did. No rubbing etc.

    While this size might look better on the truck, keep in mind you will be slightly decreasing the torque and acceleration capabilities of the truck as well as the handling (since your raising the center of gravity and using a tire with a "taller" side wall). I noticed a subtle drop in acceleration off the line with my 285/50/20's as the overall diameter is about 31.2, which is bigger than the stock 30.6 the 265/70/16 measure in at. the 265/75/16 tire will push the OD even bigger ~ 31.6?

    Comparing 20" wheels isn't quite the same as comparing a 16" wheel tire size that is only an inch taller. Wheel weight is WAY heavier than a reasonably similar tire size. The tire site I linked above caution's against tire size swaps that put you over 3% of stock. 265/75/R16 does that. Raises good awareness about brake failure (stopping distance); however, it all depends on how you use your truck. If your a pavement guy, stick with the stockers. If you need the 1/2" of extra clearance then go with the taller option. I definitely noticed a more sluggish take-off and comprimised fuel mileage (down about ~1.2mpg). If I didn't four wheel I would most definitely not go with anything other than stock (I miss 19 mpg!!!!)

    Truspeed could compensate for the difference in size and restore the factory shift points and speedometer reading.

    I never recalibrated my speedo, I just do the math. If I am correct I add 10%(for 33s) to what my speedo says and that is the real speed, I have tested this with both my navigation and the "watch your speed" signs we have in California. If you don't have them yet, as you pass they tell you how fast you are going and even flash you as if your picture was taken. Very annoying since so many are fooled and ride the brakes as they pass.

    Agreed its not an apples to apples comparison - that wasn't in the intent of my post, the point was was trying to make is that as you increase outer diameter of the tire, you decrease your trucks ability to turn it given the minor increase in leverage the tire has, I reference my set up since I have increased the OD and noticed the impact, nothing more.

    The sizes you are talking about shouldn't hurt too bad. You are keeping the same width, just increasing the diameter by one inch. Here is the calculation I use to determine tire size....
    265/75r16 265 is the width in mm, drop it to cm by moving the decimal over so it is 26.5
    26.5cm converts into 10.433inches (we are in America here and don't know what mm's are)
    10.433 multiplied by .75 (which is the ratio number, the 75, 75% of width number)
    7.8248 (I round up to 7.825) is the size from your rim lip to your tread, multiply by two
    7.825x2=15.65 now you take this number and add you rim size, in this case 16"
    15.65+16=31.65"
    This formula can be used with any rim/tire size to get rough overall diameter. It is mostly accurate, but not 100% due to differences in inflation pressure, rim width, and tread.I'll review for the college kids...
    265/75r16....26.5cm-10.433".....10.433"x.75=7.8248, round up to 7.825"x2=15.65....15.65+16=31.65" overall tire diameter
