Can anyone verify this info.?
Also, can I fit this tire on a stock 06 DC 4X4 without rub?

Assuming you have P265/65R17 as stock, the following applies. You should not have any rubbing issues, but possible if the suspension is compressed (off-roading), but nothing to worry about in my opinion.
Stock Size P265/65R17
Sidewall: 6.8in
Radius: 15.3in
Diameter: 30.6in
Circumfrence: 96.0in
Revs/mi: 660.0
New Tire Size P275/70R17
Sidewall: 7.6in
Radius: 16.1in
Diameter: 32.2
Circumfrence: 101.0in
Revs/mi: 627.0
Speedometer reading with a non-stock tire is 5.2% too slow.
When your speedometer reads 60mph, you are actually traveling 63.1mph
