I have a 2019 f150 super crew 4x4. My cargo is a constant load of about 1000 pounds ( passenger included). I知 still 900 pounds under max cargo limit and I rarely tow. I use a Firestone rear air suspension to correct rear squat which works great. I still have the stock SL tires with 50,000 miles on them with no unusual wear. The truck is used for work with hardly any off road miles. I値l need tires soon and I知 wondering if I would be better off with E1 rated tires?

 

Obviously the SLs have served you fine. E rated LTs will probably last longer than the same SL rated tire. You will get a rougher ride due to the stiffer sidewalls.

 

If you ever plow you will need the E's I found out the hard way.
