Wheel width is measured from bead seat to bead seat so you cannot accurately measure it without removing the tire first. Typically the overall width will be 1 inch greater than the internal width. So for Dexstar wheel # AM20522 the actual width is 6 inches but the overall would be closer to 7 inches.

Fora 15 inch wheel that would be 6 inches wide overall, 5 inches on the inside, with the same bolt pattern use # AM20422.I have linked a video that shows our resident tire and wheel expert going over how wheels are measured.

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

Regardless how thick the metal is, wheel #AM20443 is rated for 2,150 pounds at 50 psi. Even if the tires are rated higher than that you would still be limited to 2,150 pounds at 50 psi. Wheels tend to have 1/16 to 1/8 inch thick metal but the powder…

From the 2-5/8 inch center to center measurement between adjacent bolt holes, you have a 5 on 4-1/2 inch bolt pattern on the 5 lug wheel. According to my research, a 205/75-15 wheel can be safely mounted on a 5, 5-1/2, 6 or 6-1/2 inch wide wheel, but…
