A 205/75-15 size tire can actually fit on a wheel from 5 to 6-1/2 inches wide. With that being said, it's generally better to go with the thinnest wheel your tire fits on because that puts the weight on the wheel in the most vertical position so a 5 inch is marginally better than a 6 inch for your tires.

Another thing to make note of is your bolt pattern. All of our 15 inch wheels that have a 6-lug bolt pattern are 6 inches wide. If you have a 5-lug, most likely a 5 on 4-1/2 pattern, then we have both 5 and 6 inch wide wheels.

You didn't say what kind or color of wheels you're looking for, or if you want a tire and wheel combo, but here's an example of each size and bolt pattern for you:

15 x 5 with 5 on 4-1/2, part # AM20440
15 x 6 with 5 on 4-1/2, part # AM20545
15 x 6 with 6 on 5-1/2, part # AM20560

These are all black mini-mod wheels. Let me know the type of wheel you're looking for and if you need tires as well. Also, your bolt pattern. I'm happy to make a specific recommendation. If it's easier just email me pictures of yours if you're looking for exact replacements.
