I am building a Blaster powered Kart, and I currently have holeshot rear tires. They are pretty wide and low profile for a quad. Do these tires tend to retain their flat profile at speed, or so they want to balloon out like stock tires tend to? I am trying to determine needed clearance between the top of the tire, and the fender frame rails, which is why I need to know how much these tires will distort at speed. Any help is appreciated. BTW, I am hoping for a top speed of around 50 or so depending on gearing etc.
TIA
