Francesca is confused .
It has been shown repeatedly that the ST rating system over- rates to a 15 % factor to an LT tire .
As long as the LT tire at 2540 # rating exceeds the load carried you are good to go .
The LT tire at 2540 # rating is a much better tire than the 2830 # rated ST tire .
The ST 22570R15 load range E Chang-Shin of Taiwan Maxxis weighs about 30 # .
Every Goodyear store will mount the LT rated Cargo G26 on a trailer .
Francesca is squeamish because she does not know her subject .
She still believes an ST tire is a good tire .
That is wrong .
The LT tire is superior in every way .
