Yes yes I’m sure it’s against manufacturer’s advice, but do they fit?
It would be nice to do a few off-road country walks and I think the bigger wheels would make it easier to get over uneven paths. I know the back wheels fit (I tried them out in JL) but couldn’t check the front wheel as JL only had the four-wheel BJCM in stock. And DS was in mine, asleep. Bit concerned about the Elite front wheel lock, it looks a bit different. And also possible height differential between front and back wheels.
I could just go back to JL, but don’t want to look like too much of a weirdo
