new super swampers vers. older super swampers

is it just me or is the older super swamper boggers and tsl sx's 36 to 44 inch and others made different than the new swampers . it looks like to me the new 36 to 44 inch boggers have much more spaceing between the lugs . the older 36 to 44 inch boggers look like they have more tread or lugs because the spaceing is smaller . i like the more tread / lugs type tires i dont like the bigger spacing between lugs on the new 36 to 44 inch tires . so you guys out there that have bought these tires in the past do you think the new swampers are made different these days ? also does anyone have pics of older tires and list the size and year made or bought . also pics of the new swampers with size and year bought .
