Can you? Yes you can. Should you? No, you should not because the 65 series tire is 4.84% (1.47") smaller in overall diameter than the 70 series tire. You should never go over or under 3% difference. If you wish to go to a 65 series tire then you need to install 265/65-17 tires that are only 0.19% (.06") larger. That size will be an excellent fit. A 255/65-17 will also work well but not quite as well as a 265/65-17. A 235/65-17 will not work well and you should not install that size. Know that the 265 may rub the fender liner when you turn sharply so check that.
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.
235 70r 16
The way you have phrased your question is confusing. If you are saying that the 235/70-16 is the OEM size the answer is NO, this is not an acceptable swap. Going either way this is a bad swap. If your OEM size is 235/70-16 and you want to go to a 75 series tire then you need to install a 215/75-16. If your OEM size is 245/75-16 and you want to go to a 70 series tire then go with a 265/70-16.
The correct factory tire size for a 2001 Jeep Cherokee is 225/75-16.
Yes, you can
I guess you can - 235 85 R 16 is a bit narrower and taller. but not vitally. so it would fit
NO, the 245 tire will be smaller in overall diameter and your speedometer will be off. Handling, ride, power, and fuel economy will be effected.
Yes you can

The Stock tires are 245/50ZR16, if you opted for the premium tires, or 235/55R16 if you took the standard tires.
A 235 / 85 / 16 tire is ( 31.7 inches in diameter and has a section width of 9.3 inches ) A 245 / 80 / 16 tire is ( 31.4 inches in diameter and has a section width of 9.6 inches ) So , they are pretty close in physical size , but I don't know about the weight carrying capacity ( the 245 tire , with the lower profile . is 3 /10 th of an inch smaller diameter and 3 /10 inch wider )
Doubtful, since the radial is bigger on the r17...
