Perhaps so, but all that data will be consistent if the tire size is the same. I guess I don't know everything about these cars to say definitively, but my 10-year newer trucks with more advanced traction control systems doesn't have any issues changing tire sizes as long as you keep them all the same size. However you are a wealth of information on this forum and I haven't seen you say anything incorrect yet so I'm not going to say you're wrong, I'm just going to say my experiences with different vehicles and different tire sizes have not caused me any issues, though they have all been 2010 and newer, they have all been trucks as well, but they were all top trim level with the best traction control systems you can get. many people put different sized aftermarket tires on their vehicles and these cars even originally came with different size wheels so I don't see this causing a problem, however I'm not going to say I'm 100% correct just for disclaimer purposes, LOL
