over 3 years and 20,000 miles and no issues with 12.50's on a 8" rim,no funny wear at all since I keep my Jeep in alignment.

I am not arguing what you do anecdotally, only factually what most tire manufacturers state, minimum rim width for a 12.5 inch wide tire is 8.5 inches.

Like I said, I realize the 8 inch rims are a common fitment with 12.5 inch wide tires on Jeeps. I am torn myself with this very question. My Jeep is a DD and I do not "wheel" but I do go significantly off road to explore on occasion.

Well if you measure most 8" rims they mostly measure closer to 8.5" anyways.

Not saying I'd follow their recommendation, but when a tire manufacturer recommends a wheel width, I'd have to imagine it's based on the conventional method of measuring wheel width.

Well I wish they could learn how to make tires the correct sizes,like what is stamped on the sidewall.

Another issue I had with 10 in rims was always getting crap stuck in the bead and loosing air. There were times when I had to have the ties remounted to get the bead cleaned out. I havenít had this issue since I switched to 8 inch rims.

For a 12.50 I have always preferred the 8" wheel so I could run a little less air on the street to have a better ride and not be wearing the outside edges like it would if it was mounted on a 10" wide wheel . Also a 12.50 tire is not a big enough tire to justify sticking way outside the fenders as they do on a 10" wheel . It just makes it look like a poor choice of wheels for the most part . a 12.50 will protect an 8" wheel more than it will a 10" . 10 is ok if you are running something like a 14.50 then you have a big tire on a big wheel , a better match .
