tire weight question

I noticed going from amazon to the manufactures websites the weights are different. I listed them here.

STI website black diamond ATR 25x12x9 is 29lbs, and 23x8x11 is 17lbs.
GBC website Dirt Devils 25x12x9 is 24 lbs and 23x8x11 is 14.50lbs

Amazon GBC DD weight 23x8x11 is 16lbs and 25x12x9 is 28lbs
STI BD weight 23x8x11 is 16lbs and 25x12x9 is 21lbs

Total weight BD on amazon is 37lbs, DD weight is 44lbs =$189.00 amazon
GBC DD =$157.00 amazon, cheapest I found is Rocky mountain atv Black Diamonds for $178.00

Makes you wonder how many companies actually have calibrated scales? I’m considering getting away from the tractor tread tires, good example few years ago me and grandpa were goin to check the cows and there’s this ditch off to the right side of the slight hill i let grandpa ahead to see if he makes it up, he does and I go down to 2nd get half way up then all goes wrong. Start sliding i know to put my feet up cause of the ditch slide in the ditch and barley teedering the something gives out underneath and slides down and left, back fender is bent in but after he pulls me backwards it’s straight as new. Yes I had my tires aired down 2.5 pounds. I’ll run these dirt devils until they wear out, looked at all the tire choices and not to many radials for a stock 2wd 300 rims, the Black Diamond ATR has my eye.

Amazon price dirt devils front for mine $55.69, and rear is 101.18, total $157.00

Black diamond ATR prices amazon front $66.39, rear 122.49, total $189.00
