If you expand tread width especially knobby, you need to account for anything the tire may end uf rubbing against. These tires They are useless in snow. They will rip your clothing and gloves aprart. Brakes become useless vey quick and need fast adjusting because of the tire wears. I have never gotten a flat. Yes they look "cool" and people look and wonder "what the hell?" but you really need to consider where you would be primarily be using the tire. If it is all day indoor and outdoor, you better do a good evaluation. They WILL DESTROY indoor house molding. I have piles of clothes I threw in the garbage.
