"Here are some pics of the positioning of the my spare tire carrier. I have two spare tires; one from a Nissan Altima (years 2002-now) and one from a 2004 Nissan Quest Mini-van (not sure the range of years). All the wheels must be the 5 lug, 4.5 inch / 114.3mm mount, and are typically a 16 inch by 4 inch rim. Tires vary, with the Altima tire being a 135-90-16, and the Quest tire a 135-80-16. The larger numerical aspect ratio (90, vice 80) has a larger diameter than the latter.
I hope to have this project completed in the next 10 days.
