I post what follows as a separate item because I didn't want to hijack or dilute that thread:
Background.
When I purchased the Jeep later to become infamous as the "Bubbacon," it came with Yokohama 33 x 12.5 Super Digger-Vs mounted on 11-inch wide rims. Those are the tires and rims you see on the Bubbacon in my sig-pic.
I also had at that time a set of 8-inch wide rims which I preferred only because of aesthetics.
So, never one to leave well enough alone, I trucked the mounted Yokos and the set of 8-inch rims to a Goodyear store with the intent to have the 33 x 12.5 Yokos swapped onto the 8-inch wide rims.
The Goodyear guys refused to install the 12.5 Yokos onto the 8-inch wide rims. Their explanation was that according to Goodyear tire-width to wheel-width fitting guidelines, the tires were too wide for the rims.
The Goodyear gurus went on to explain that 12.5-inch wide tires fitted onto too-narrow wheels would cause premature wear in the center of the tire because the center of the tire tread would bulge at normal road inflation pressures. Related to that were possible driveability and safety issues because of the overly narrow tire to pavement contact patch.
(One can imagine lawyers flying lazy circles over the Goodyear store at this point.)
Aftermath.
I thanked the Goodyear guys, took everything home, refinished the 11-inch wide rims and have since lived happily with the original tire-wheel setup.
By way of confirming the Goodyear experience, however, I did some web research on the tire width to rim width equation. I found the following table:
That table, rigidly interpreted, would appear to confirm my Goodyear experience.
Question. (You thought I would never get there)
Would someone who has "REAL" expertise, as opposed to my anecdotal expertise, please chime-in and expound at-length on this whole tire width to rim width question?
Given all the tire and wheel swapping being done by Jeepers, I think it would be a good idea if the tire-challenged, like me, were educated on the topic.
Thanks in advance to anyone willing and able to shed light on this problem.
(You know who you are.)
Regards,
Gadget
