I want to purchase some 15X10 Vison Soft 8 wheels. With the intent to run Mickey Thompson 33X10.5X15 AT tires. The offset looks to be -39mm, which looks to shift my wheels out considerably from the stock 16X7. According to the calculator 2.7" further out. Before these wheel tires go on the JK will be getting the MC 2.5 overland kit put on her. Will this increase to the outside negate the need to change any steering stops? Is there also a risk of the wheel not fitting over the caliper/rotor assembly? Lastly will I need to chop or replace my factory fenders? Thanks in advance for the input.

You can fit a 15" wheel, but most people tend to go with a 17" which leaves room for a brake upgrade somewhere down the line. With a 15 or 16" wheel you eliminate that possibility. Is your thought on a 15 just along the lines of smaller wheel will accentuate the 33 to look a little bigger than it actually is, giving you a bit more rubber on the sidewall? Trying to stick with a 33x10.5 rather than 33x12.5 in effort to reduce some drag?

Not at all resharp. I was trying to save some scratch and a local Jeep buddy suggested this. This is why ask these questions before making these purchases. I can't think of why I might need bigger rotors, but who knows if I tow around a pop up, I may need the bigger rotors when I come screaming down I-70 sometime.

Wasn't sure. Everyone likes a different kinda look. Down here lotta people like 20" wheels with 35s. LOL. If you're not opposed to spacers, noticed there's a set of Spidertrax for $90 in the Aurora area....I'd bet $80 takes em home, and at a fair price. Could just use those with your factory wheels, throw 33s on and call it a day......but I know people have differing opinion about spacers as well.

Be careful running a 10.5" tire on a 10" wide wheel, there isn't much to hold the bead when you air down for offroading.

Exactly. A 10.50 inch wide tire is too narrow for a 10 inch wide wheel.

Check the specs listed for your tire of choice. It should state a rim width range, and sometimes even shows the width of the rim used when they took the tire height/width measurements.

For example, looking at the mickey thompson baja atz p3, the approved rim widths are:
31x10.50x15 = 7" - 9"
33x12.50x15 = 8.5" - 11"

Not saying that you have to follow those guidelines, just pointing out that the tire mfg's post their recommendations.

Just a heads up, no aftermarket/1 ton tie rods or drag links (Synergy, Fusion, Ruff Stuff, Teraflex, etc.) will fit with 15's. A lot of 16's are also in the same boat.

Thanks for the input BoraBora. I will keep that in mind as well.

So let me ask this. If I snag stock 17" wheels, (this is just hypothetical numbers I have not researched stock 17" offsets) and they have an offset of +50mm. I buy 1.5" spacers and install these. Does this mean subtract 38mm from the 50mm and now my offset will be +12mm?
