BH"s will be a nice upgraded tire for you
as for being TALLER, this I am not 100% on, as I believe BH" tend to run SHORTER than there CLAIMED size!
feel free to do a internet search on this if you like, but if My memory recalls correctly they tend to run about an inch shorter than they claim, like a LOT of tires do from a LOT of brands
VERY very very few atv tire makers tires run true to there side wall sizing, it just IS what it is, , some run taller, some run shorter and FEW are correct is MY experience!
but any way it should be again a slight upgrade in ride and handling for you, and they do last a LONG time, and work well in most conditions,
so a GOOD overall tire for you for sure! IMO
