235 / 65 / R17 is ( 29 inches in diameter and the tire section width is 9.3 inches ) 245 / 70 / R18 is ( 31.5 inches in diameter and the section width is 9.6 inches )
Of course you can but, this is an unacceptable swap. The 245/70 series tire will be 3.16% (1") too small in overall diameter. Your speedometer will read 61.9 at a true 60 mph. Braking, handling, ride, performance, and fuel economy will be adversely effected. If you wish to go to a 70 series tire then install size 265/70-16 which is an excellent swap. 255/70-16 is acceptable but not as good as a 265/70-16.
a 245/70R 16 tire has a diameter of 29.5 a 225/75R 16 tire has a diameter of 29.3 which is only .2 inches larger on overall diameter. I ran a 245/70R 16 on my 02 Jeep Grand Cherokee, with only a slight problem which occurred when I turned the front wheel all the way to the right or left. I would rub the inner fender. The 02 Jeep Grand Cherokee I own used a 225/75R 16 as the factory tire size
The biggest stock tire I have seen is a 245/70/16
If 235/70-16 is the OEM tire size then switching to a 245/70-16 will cause your speedometer to read 58.8 at a true 60 mph. You will also have slightly less power.
245/70/17 Most models come with 245/65R17
235 / 70 / R16 is : 29 inches in diameter / section width 9.3 inches / section height 6.5 inches --------------------------------------------------------------------------------------------------------- 245 / 75 / R16 is : 30.5 inches in diameter / section width 9.6 inches / section height 7.2 inches
No number specifically indicates the height. You can however figure the height with a little math. As in 245/70-15 the 245 is the width of the tire in millimeters. The 70 is the aspect ratio which means the tire's height is 70% of the tires width. So on this example the height of the tire is 171.5 millimeters.

265/70/16 or 265/70/17 or 245/70/16 tire size for Tahoe is located on drivers door
If you have enough clearance for the wider tire, yes. You can but it is not advisable. The 245/75-16 will be 3.88% larger in overall diameter and it is never advisable to go over 3%. Your speedometer will read 57.6 at a true 60 mph. You will also have a slight loss of pulling power. You can however go to a 245/70-16 which is an excellent substitute and is only .75% larger.
