Measure the fork width like tds101 said and measure your brake calipur width,, where it would go around the wider tire..
I betcha a six pack of beer your rims are fine for 2.15" wide Big apples,, Umm IF I loose this bet,,
It's gonna be cheap beer and you gotta come get It !

Must I take the wheel off? I can remove the tire partially to measure, and I already measured the fork. And you're probably right. The rim is probably a generic, chinese-made one, and the're the same front and rear, and since the rear holds a hub motor, I doubt it's a skinny rim, because then it would have to be super strong, and this bike isn't super expensive.
