I had someone from BMIKarts "help desk" say the same thing for my bike despite the 63-559 (26×2.5) tires so I got a 60T as a 56T (415) and both were sh!t.If you use anything smaller than a 60 tooth axle sprocket you will just smoke belts. A 30 series should hold up just fine as long as you use Genuine Comet belts. You need to upgrade to the 40 series with the big blocks because the torque can overpower the grip of the belt due to the angles of the shieves.
The 60T made the bike do a wheelie on just about every take off and ate the belt by dragging it down into the fixed driven sheave rivets.
The 56T was more of a nose bouncing lurch but again only served to make the rivets eat the belt.
48T was good accel/top speed comprimise but interfered with other requirement aspects if the build which is why I've stuck it out with a 36T.
Do You suppose maybe I'm sending significantly more power to the road out of my 208 than the 10hp I estimated?
Seems maybe I need to get a 40 series on it and use the 30 on something else down the line
