What sizes do you want to see in a 30" Pit Bull tire and do you want a tire that is more like our ATV design or LT design? Do you like the Rocker or Growler design more? Do you want the same tread depth as our ATV tires (32/32 front and 36/32 rear)? Do you want the tires to be bias or radial? Currently our ATV/UTV tires are radial 8ply-rated. Weight is a factor, but our 30" if made as an 8ply-rated radial will most likely be 45 lbs. So reducing the tread depth and ply-rating and making the tire a bias may be the trick.
