Hi guys, I haven't posted in a few months, but I have a question. I am looking at replacing my Falkens with one of these sets of Nittos: Nitto Terra Grappler AT : LT285/70R-17E1 126R B Treadwear: N/A Speed Rating: R Load Range: E1 or Nitto Terra Grappler AT : P285/70R-17 117S B Treadwear: 500 Traction: A Temperature: B Speed Rating: S Load Range: SL What is the main difference in these two? From what I can see it is the Speed and Load ratings. I have a 1500 series Crew Cab. I don't pull a trailer very often. Do you guys think the higher load rating model is worth it on a 1500? Or would those be more recommended for an 2500+ ? Any input is appreciated, as this is only the 2nd set of tires I have bought for a pickup.
