Wheel and Tire Rabbit Hole

I want to swap the 18” wheels and tires on my 2026 ORP Premium and go with 17” rims. I will take the vehicle off road beyond simple fire roads. I may lift the truck someday but not today.

I am going to put KO3s on it unless I can find a compelling reason for a mud terrain that behaves as well as the KO3s in snow. I prefer a taller skinnier tire for winter performance.

Specifically, what wheel dimensions do I need to look for as well as tire size? I do not mind going a bit taller than stock. I never put aftermarket wheels on my vehicles, but I assume a forged wheel is probably preferred. Will the 17” wheels off the TRD Pros work for my purpose?

Finally, do I really even need to go down to 17“ wheels? I’m not planning on beating the bejeesus out of the thing.

Thanks for putting up with this post since there are a million of them
