Lots of heavy 5er's come with inadequate low quality E rated tires. Many don't have problems; but some tire scrubbing, overloading, running fast, road hazards, sun, or just every day bumps can make them very dangerous. Some replace with LT's, many just replace with good G rated ST tires. They don't have to be expensive, Sailun makes a good G rated ST tire that I've run on two heavy 5ers very happily for tens of thousands of miles.
If you have a heavy 5er with E rated tires I'd recommend replacing them soon with G's.
Our FW isn't overly heavy but yes, I went with G rated tires.
