comparison ST vs LT Goodyear

why are ST tires overrated ?
From the tirerack website .

Goodyear ST 235/80 R 16 rated for 3420 # on the sidewall
price = $ 135 each
weight = 34 # each
section width is 9.2 "
tread width= 6.8 "
diameter is 30.7 "
3420 # at 80 psi

Goodyear LT 235/85 R 16 rated for 3042 # on the sidewall
price = $ 157 each
weight = 50 # each
section width is 9.3 "
tread width= 7.0 "
diameter is 31.7 "
3042 # at 80 psi

So the Goodyear ST tire is rated for 112.4 % higher load rating than the equivalent Goodyear LT tire .
And they will sell this ST tire for only 86 % of the LT tire .
And the ST tire has less mass for cordage , plys , caps and so forth because it weighs 76 % of the Goodyear LT tire .

This is very telling as to how much lower the ST standards are in relation to the LT standards .

Further the ST tire has plainly stamped on the sidewall " for trailer use only " .
The LT tire has no disclaimer .
