>>>Did you experience much in the way of ride harshness when you moved to the E rated tires? I would still do E rated tires, but I might consider moving from the factory 20” wheels to 18” wheels <<<
I never drove the truck with other than “E” tires, so can’t comment on harshness of ride.. it went straight from the dealer to Les Schwab tires for the swap. The ride seems fine to me. I have the stock 17″ steel wheels. I think 18″ and especially 20″ wheels are strictly fashion accessories.
