More fuel for the fire:
For those who point to the regulations and the testing required, how do you reconcile the fact that LT tires are testing at lower loading levels than ST tires for the same size? Doesn't this mean that ST tires are tested to more stringent conditions than LT tires?
Barry, I'll pose my response as a question, since you are the tire engineer. Is part of that higher load capacity of the ST tire due to the fact it can be rated for a lower speed ? More speed equals more heat for a given load ?
Or am I off base on that idea ?
Thanks for weighing in on the discussion.
Yes, the lower speed rating does result in a higher load carrying capacity.
