I also spoke with Agile at length about this last week.
It was my understanding “and maybe I misunderstood” that they could get 275/70/17 with their ride improvement kit tat generally lifts the vehicle about 1.5”.
As t was explained there are censors in front of the tire or “radar” these radars are very specific with regard to angle and aspect to the center of the tire. As suggested the censor calculated revolutions with miles so forth and so on and comes up with a algorithm that relates to specific parameters the vehicle is programmed to identify.
Imop it’s all kinda a bummer. I’m on the fence. The features tied to these radars or sensors are in some ways neat and or slick. But you know in many ways I’m a purist I like a vehicle to be as simple as possible all metal, gears fluids and as few electronics as possible. Electronics generally just fail and when they do they are expensive. In this case electronics seem to be limiting the real potential of this vehicle as least with regard to off road. Yes I get it’s a van and it will never be a rock crawler.
The whole thing reminds me of when I was a kid and into BMW’s. The M3 was obviously the pinnacle. I think it it was between 1995-1996 or just early 95 to late 95 that BMW changed something electronically that made the earlier car highly modifiable and the later one very limited. Imop the E36 M3 was the last real M3. After the E36 after electronics took over. The e30 M3 was and imop is still the best M3 and a real street legal race car. Even e36 was shameful at the time.
I can’t help being new to these sprinters that depending on your intended use the pre 2019 may be better for many.
I just got confirmation from Agile that they have been running 275/70/17 without issues. Slightly smaller width and overall diameter than the 285/70/17.
Diameter is the problem. The wheel speed being different than normal vs. the factory 245/75/16 tire.
If you don't have GPS and distronic you can run 35s.
