One note on the spare: I’m running a 275/70R18 KO3 on the OEM rim. It fits the spare space fine, but it’s large enough that the trailer hitch shank can’t slide in all the way anymore. Currently, I’m forced to use the second hitch pin hole, which noticeably affects the suspension.. I plan to cut the shank down soon so I can go back to using the first hole and have my GX sit level again with the trailer on.
