Pygmy - What style Black Rhino wheels are you running? I was thinking about running Black Rhino Havasu wheels (45mm offset) and BFG KO2 265/70R17 on my 2020 4x4. Agile's site says this combination should have worked....
45 mm Offset
For van owners looking to retain factory-like fit we suggest the 45 mm offset wheel. Tires up to 265 width sit within the wheel wells with no “poke”. Because of the higher offset and narrower width, no mudflap or fender modifications are required on the new (VS30 – 2019/2020+) Sprinter for tires 265/70-R17 & smaller.
For what's it worth I just mounted 275/70/17 BFG K02 on Black Rhino Havasu to a 2020 4x4 144". I got the 38mm offset. I did install the no rub fender kit from Agile and it really gave a lot more room for tire. The 275's are about 1/2" from rubbing at worst point of turn radius....very happy with the setup but just mentioning that because I would be shocked if the 265's did not rub without a fender 'adjustment'.
The tires are slightly louder than the factory but the bigger rubber soaks up washboard and pot hole noise much better (don't get the tin can rattle sounds as much)....that should all get cured with an interior though.
Been running these tires for many years and have quite a different experience than sanomechanic. Never had to re-balance. Overall local climate and driving conditions probably play a role. I live in Oregon where summer highs aren't extreme and freeway driving is about 75 tops. Not sure if that has something to do with it. Who knows, I've never been disappointed with them
