hmmm :/ i would think the belt would slip some if you dont tighten it up. just shift the gears like a atv or dirt bike. 1,2,3,4,5,6 that way it graduallly increases

im running a 41/2" in the front and a 31/2" in the rear and that does 20mph with 20" tires so 51/2 in the front and a 2 in the back should get at least 30 with 18" tires

I say 6 or 5 they are best like i heard on fearlessfront's channel and they do nut run on clearance issues, and they have enough circumference so the belt won't constantly slip.
