The majority of ST tires while having a 300# to 400# rating advantage, but only to speeds to 65 to 75 mph. In addition most don’t trust their ST tires to anywhere near their rated capacity. I am running my LT’s at 82% of rated capacity how many feel safe with running ST’s at 82% of capacity?

I'm sorry if you misinterpreted. I didn't say you drove at excessive speed. In your original post (from memory) you said the LT's offered less load carrying ability but a higher speed rating....and in this case it would require new wheels. The only positive point out of that is that you can run at higher speeds, which isn't recommended pulling a TT. So that was what my comment alluded to. I wasn't trying to "poke" you.
As far as LTs giving a higher speed rating and lower load capacity my take is this (right or wrong); a higher speed rating refers to a tire's ability to "hold together" at speed from centrifugal force.....bonding to the carcass more or less and the compounds/designs required to do this. When driving a sports car or hot rod it's extremely important that the tread stay connected to the carcass of the tire at high speeds or if you're inclined to do a burn out - or cars/trucks running down the highway at higher speeds. The load capacity refers to a tire's ability to ....."carry/hold" a specific amount of weight - 2 different things to me. The ST then takes that "carrying" capacity and tries to complement it with a suitable speed rating that takes into account what the tire was designed for -carrying a large load. Therefore, IMO you get a stouter "load carrier" but not so much a sports car tire.
You may not agree with this but it's what I've come to think from everything I've read and observed about tires over the years.
