Just for interest,

I have the Tire and Rim Association Handbook (tire industry standards organization) on my desk. The recommended rim widths for P235/75R15 tires are: 6, 6-1/2, 7, 7-1/2. The permitted sizes are 8, 8-1/2. I typically run 8 (wider is better within the permitted sizes) Wider than permitted starts to give mounting, un-seating and other problems.

If you need the permitted widths for other tires, let me know.
