Well we have had six pages of information, opinions and rhetoric. By now a person should be able to decide if they want LTs or STs.
One thing is for sure, the trailer industries; horse, boat, utility and RV are not about to change from STs any time soon. Maybe someday when cars and TTs are computer driven at crusing speed around 150 mph or levitated on magnetic rail highways at 200 mph; tire requirements will change.
Till then, the millions of TT and 5ver on the road will continue to roll along on STs.
Safe travels to all.
