So just to shed some light on what
@Dcsnet found with his specific case, the Rough Country tool 90019 did disable his park sense sensors when selecting a tire size over 33.75”. Like I said, I’m on 35’s but my tool is set to 33.25 since that is what my tires actually measured at when on the vehicle. That gave me the most accurate speedometer reading. We did get Dcsnets ParkSense to work when he adjusted his tire size to 33.75. That said, it appears that if selecting a tire size larger than 34” it may disable ParkSense. Unfortunately we don’t know the exact cutoff point, nor do we know if all selections above 34” will disable it. I will say that you should be fine running 35’s since the actual tire size measures less when setting the programmer. But if going over 35’s then this may not be the solution for you.
