My truck came with the 245/75-16's on the stock 16 inch wheels. Is this the tire size that is recommend? I was poking around on tirerack and tires.com and it looks like there was an optional size of 265/70-16.

The 245/75-16 is the recommend tire size for the 4 door 4 wheel drive
I just looked at Tirerack and that is the only tire it shows as a option for your Tahoe... However I don't see any reason you couldn't run the 265, Just check your clearances. The 265/75-16 was a option available on the Z71 2 Door 4x4 model Only. It was not offered on the 4 door version to my knowledge.

I forgot where I saw it. I was poking around somewhere and I saw an optional tire size of 265. Basically, what I am asking is should I just stick with the 245s or is it a nice upgrade to the 265s?
For example, my Mustang came with 245/45-17s, I stepped up to 255/45-17s and the car rides a lot better. Not quite as hard, less fender gap and it squats much better on the rear tires when I nail it at a light. Would I see any differences on my Tahoe going from the 245s to a 265s?
Thanks!

The 265's are just over 1 inch taller than the 245's. Your speedometer will be off by almost 2.5 mph (you will be going faster than it is telling you). I run 265's on my 97 2-door without any issues. I suppose you could consider it an upgrade.

The first number in a tire's tire size information refers to width, not height:
"For a tire such as "P225/50R16", The first number in the tire's size information indicates this tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel. This measurement is also referred to as the tire's section width."
The second number refers to height:
"The 50 indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43". If this tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall."
The correct size and inflation specs for tires for your vehicle should be on a sticker on the rear edge of the driver's door.

Thanks for that explanation, but I know what the numbers mean. In my earlier post, I mentioned that the 265's are going to be taller. With the tire sizes that the original poster mentioned, the 265's are going to be bigger in diameter.
245/75R16 tire:
Sidewall 7.2"
Radius 15.2"
Diameter 30.5"
Circumference 95.7"
Revolutions/mile 662.0
265/75R16 tire:
Sidewall 7.8"
Radius 15.8"
Diameter 31.6"
Circumference 99.4"
Revolutions/mile 637.0
All this will equate to his speedometer reading 3.9% too slow.
Now, if he were to switch to 265/70R16, the overall diameter will be nearly identical to the stock tire diameter.
