I bought the wheels for the looks, and the tires were a bonus. I'm going to try and fit them with just the lift kit. If there's excessive rubbing under normal conditions I'll look into trimming.

I also might just sell the tires before they have any wear on them and downsize just a bit. I love the look of them but I definitely don't need a mud tire, I'd be fine with the all-terrains.

I appreciate all the help and input from you guys. There are a lot of things I know some stuff about, and this isn't one of them!

I did get the lift installed, here's a quick pic of the truck with the lift and the wheel/tire combo:

You'll be okay, lots of people run 285s without many issues. As long as its not getting stuffed all the way in the wheel well, you'll probably be fine.

Those wheels probably have enough offset for the tires to clear the UCA without spacers too, which is good

Those G003s are very good tires too

A few people have mentioned the Upper Control Arms. I did a quick search and found this from JBA Offroad:

"JBA Offroad manufacturers upper control arms (also known as UCAs or upper a-arms) for the Toyota 4Runner beginning with the 2003 model year. With the right modifications, Toyota 4Runner models are wonderfully capable off-road vehicles.

All Toyota 4Runner models have independent front suspension and require replacement of factory upper control arms when lifted. If factory UCAs are not replaced, your Toyota 4Runner alignment and clearances will be both incorrect and unsafe.

When Toyota 4Runners are lifted, caster is lost from the front-end alignment. Caster is critical for stability over 45 miles per hour and returns the steering wheel to center after going around a corner. Additionally, factory upper control arms often rub on the front springs at certain articulations. If factory a-arms are not replaced when lifting a Toyota 4Runner, expensive and dangerous damage is likely."

I know their goal is to sell product, but is this something I definitely need to be concerned about?

For your use, no, you should be fine. If you’re going to be getting into more serious off-roading and upgrading to proper coil overs then yes as in that scenario the UCA limits travel.

As far as trimming, it’s not too much for 285’s. You’ll have to remove the front mud flaps and trim the lower inside lip of the bumper for sure, but not much else.

Well maybe I got lucky (buying these without knowing the backspacing, etc)...

I received the RRW Extended Lugs today, and sure enough they let me install these wheels without having to replace my wheel studs. As for the clearance, what do you guys think?

I haven't had a chance to drive it because I am replacing a caliper tomorrow and have the old one off, but I think they're gonna work!
