Biggest tires for 2019 1500 Limited with ORP

[jleather]

For my 20'' wheels, is the biggest 275/55R20 for no rubbing? Deciding between KO2's or Nitto Ridge Grapplers. Wanting to stay stock with no lift. Thank you much!

I've seen 35x12.5r20 fit on a larmie with ORP. Fit the wheel well OK, but rubbed on the control arms. But it was minor.

That said, you should be able to fit 33's easily. So i'd try a 285/60r20.

I have 295/65r20 on my non-orp truck with just a 2.5" front spacer. Fit's well and the 2.5" lift allows me to fit the 35inch tall tire.

I've never had ko2's, but have had ridge grapplers and they're probably the best tire you can get. They do run wide though, so you need to be careful with the inside wall of your tire touching your upper control arm.
