Too many variables come into play when you make a statement like that. Just because it may not be apparent at the time you are still doing something that is not recommended. Yes, it is common knowledge that driving a "part time" transfer case like the 231 on dry pavement isn't a good situation, hence the term part time as opposed to full time. Similar to driving a spool on dry pavement, normally the tires slip and suffer wear when making turns. Differentials are made to compensate for the speed variations in side to side wheel speeds while turning. The same can be said for front and rear axles and drivelines when turning as well. With a 231 in 4h the front and rear drive shafts spin at the same speed. Any difference in tire size or wear, or any type of turns will put the drivetrain into a bind of some kind. Something has to give eventually. If you are lucky it is the tires that will give but prolonged periods of driving in anything other than a straight line will cause unnecessary wear and possible damage to your transfer case, drivelines, or axles.
