C vs E rated tires

[JustBillin]

I haven’t experienced “E” tires on my Raptor, but the “C” to “D” swap really didn’t create a ride quality issue for me. Raptors have "springy"springs, 17” wheels with a ballonish sidewall height, and you definitely don’t need to pump up “E” tires like your driving a Super Duty tow machine!

I recently completed a 1200+ mile road trip from WA to MT and back after switching to E rated KO2s in 325/65/18 and noticed no real difference compared to the "C" rated oem tire. PSI at 38 rode great.
