285/65/20 On Stock Rims With No Lift?

Thanks for the reply. I have 20” platinum wheels and a 2.25/1” level.
I was going to run 275/65/20 but I want 285/65/20 if I can. I do not want to have to use wheel spacers for UCA clearance.

How much space do you have between your tire and the UCA? Do you have any pics of your setup on the truck?

 

I’ve got the Bilstein 5100s on all four corners, set to the middle setting up front.
No idea how much clearance I have from the UCAs, but I imagine it is pretty close but I do not hit them.

I was able bend the skid plate out of the way and removed front mud flaps, but I still make slight contact with my TRD sway bar when near left full lock.
