Upgraded to Toyo AT3 285/70/17 tires today and the alignment tech maxed out my caster at 2.9. Now before I purchase these UCA STD High Casters, I have one important question that I could not get affirmative confirmation while searching online, will they will rub on the tires. My Pro is lifted with Eibach's drop in springs for the factory Fox Shocks and running the factory Pro wheels. Hopefully someone with a similar set up can confirm this for me.
Even after reading their notes I'm not sure where my wheel specs fit in due to them being 17x7 with a +4mm offset, am I over thinking this?
Please Note: 32.5" and larger diameter tires need aftermarket wheels with less then factory wheel back space.

Any tire that is 32.2" diameter and smaller there is no fitment problem.
