Buenos Noches, Searching has lead me to some pretty sad threads where this question has been occasionally asked- but never answered as far as I can tell. The best general consensus I can find without any valid proof, is that a 35" tire will not fit the stock tire location whereas a 33"-ish tire might??? I'm set to attempt replacing my factory spare with a newly acquired 285/70/17 full size spare matching my set up and I know it will be a tight squeeze. The tow package electrical hookups near the tow hitch appear to be one issue that might compromise maximum fit. If you happen to be reading instead of indulging in tacos, cervezas or tequila (a better choice than this), please let me know your experience trying to fit a big circle in a round hole. I'll post my experience soon. Just want to get a new discussion going! Salud!
