I'm going to LT's on everything.
I keep loosing "gator backs" off of ST tires or having knots show up, with broke bands (and I've had both happen when trailers were stationary). Lost 3 within the past 10 months on 2 different trailers while stationary, and some were less than 2 years old (and yes I check the dot date).
So when my STs go on given trailers, there getting replaced with LTs if they are available.
