Need help after changing to BFGoodrich KO3 265/70R17

I like the bumper guards. Are these metal or plastic reinforced

They are plastic reinforced. The extra kit comes directly from the dealer here in Kuwait for about mid levels to the highest, just like the AeroS kit in the LC300. Personally i wish they didnt come with it, specially the panel on the doors. It's just too many different shades of grey colors.

I believe the kit is from www.modellista.co.jp seems the same to me

Yo, don’t worry too much about it, i installed custom size/offset Evo Corse wheels with Kumho 275/70/17 (i was supposed to put 285) and everything is fine, i went with 40psi on the tires at first, it was a little harsh ride, then aired down to 35psi.
Higher PSI give you better gas milage and less wear and tear, but the ride is harsh and traction is compromised due less wheel footprint on asphalt, lesser PSI gives bad mileage and more wear and tear but better ride and more traction, you can check my thread and see my build.

Sorry for being late, but i hope those pictures help, I went with the offset my self, i saw people doing +40 with 8.5" wide wheels, so i thought shave 0.5" from the wheel to save weight and go with more offset.

If your downsizing, then on the speedo would reader a bit faster . Eg if your doing 100Kmph shown on speedo, actually it would -2 to -3kmph , that roughly 97-98. You may loose a bit of ground clearance on OEM setup, But ur absolutely at a better advantage. No tune required, in terms of wheel if the bolt pattern and offset remain same.
Mine FE truck was delivered with 265/70R/18. But now models are also being delivered with 20 inch rig with classic grill setup. I have not looked at the offset setup. But looks clean set up

Maybe check your speedo against a GPS.
