To the OP, don't take this the wrong way, but two blowouts in a row on the same tire, and I would also be looking to see if there is a possibility of some other cause.
You said you smelled hot rubber. Is it possible the tire is rubbing? Is it part of a dual? Is the other dual properly inflated? Is the brake locked or rubbing on that corner, that can cause the rim to heat, degrade the tire, and result in a blowout.
Have you weighed the corner to see if you are within the tire's limits?
Before you flame me for sounding like a rep for the tire company, my real interest is YOUR safety. The problem may well be the tire. However, you should eliminate any other potential causes before heading back out on the road.
I am just trying to politely say that two blowouts in a row, in a short period of time, on the same corner don't necessarily point to two bad tires in a row
