Every 4x4 since they were introduced should not be used on dry pavement for any length of time. The reason being is that they all create some driveline bind. Most of the time they figure the 4x4 system will be used in slippery conditions since thats the whole purpose of of it. The 4x4 system relys on that slip to take up any binding. Bottom line, yes you can run 4x4 on dry pavement, but don't do it for extended periods of time. All 4x4s are this way, even your tahoe.
I'd like to add something to this thread. When I bought my first 4X4, a 77 Plymouth Trailduster (Ramcharger with Plymouth badging) I was new to how a 4X4 worked. It had the NP203 full time transfer case. The shifter knob on the floor was marked top to bottom: lo loc, lo, neutral, hi, hi loc. All normal driving was in hi. When I shifted to hi loc, the transfer case locked the front and rear drivetrains together so there was no slippage between the two like in normal driving. When taking a corner in hi loc, the truck slowed to a crawl and stopped. I had to back up in the same direction and then I was able to shift out of hi loc. It was the same in low. Bottom line, when a 4X4 is driven on hard surfaces with the 4WD system completely engaged, it will cause driveline binding, and can eventually lead to major breakage of very expensive components. 4 wheel drive should only be engaged on slippery surfaces to allow slippage between the front and rear drivelines.
I learned fast. That truck never broke and never got stuck. Sometimes I wish I still had it.

77 Plymouth TrailDuster--If you still had it, all of the "non rusted" parts of it would fit in a bushel basket by now--Those things were tough, but a little rotten after a few snowy winters.
Snowy winters? Not here in southern California. We don't have the rust problem you guys do where it snows every winter. So If I would have kept it, it would not be rusted out. And yes, it was a tough truck. In fact, I saw it a couple of years back. It still looked in good shape.
