I upgraded to 285/75R17 per the knowledge of this forum, thank you. Amazingly the spare that is now 3.25" bigger diameter fits in this area despite tire shop saying it would not. Without this video here I would have assumed the shop was correct. A couple of observations: the spare moves side to side a bit so I'm wondering if there is a stud or some other way to better secure that people have used ? This side to side movement was also evident as chafe on factory Michellin LTX A/S ( date of manufacture week 41 of 2003 ) that was just replaced.
