I wasn't going to post in this thread about staggered setups but there are quiet a few here on this forum that have them (at last count a little over 10 I have talked to) so wanted to throw in my two cents.The issue isn't really the stagger, it is how it is programmed from the factory. If the factory setup is staggered then the control software reflects that and no issue. When you change off of the factory configuration, that is when problems developed because the software reads the front and back wheels as travelling at different speeds, indicating slip. What that threshold level is, is completely up to each vehicle's programming.
I guess I should have mentioned this 1-2% difference staggered diameter setup is the tolerance that most manufactures seem to allow for. Some even go up to 3% before you start having issues. I don't have a lot of experience with the Mach-E only owning it for 7 months but based on other AWD cars I've had with staggered setups and working with Terrance from Signature Wheels with all of his setups over the last several years on AWD vehicles, so far haven't experienced any problems. We try to stay within 1% always even though I have seen others go as high as 3%. I understand there can be problems that may arise and if they do, we can easily adjust for it changing the tire sizes and move on.
That said, a few weeks ago I changed the summer performance tires on my wheels from 255/45/20, 295/40/20 (1% difference) to 245/45/20, 275/40/20 (0% difference) all season tires. The Mach-e will be the only vehicle I'll have to drive in cold temps and light snow.
