Welcome to TBN.
I don't have a foreman but from what I've seen, I concur with buckle97.
Those are the most common sizes which helps pricing as well. If you need rims, you'll have to watch the bolt patterns and offsets more closely.
Thanks guys. It wasn't for me though, afriend just bought tires for his and put 25's on the back and 23's on the front.
I told him that wasn't right they should be the same all the way around.
