Tire/wheel advice needed

Trying to figure out which way to go. I've priced out 17" tires (285x70x17) Duratracs and wheel spacers using stock rims. I've also priced out 15" rims (mob tko) with (33x12.5x15) Duratracs and the prices of both combos is really in the same ballpark. Does one of these combinations have any benefit over the other?
My jeep is a 2013 jku and my DD. I do haul a trailer on occasion.

The 33 12.50 15 will be a little taller and wider.

The 15s will save weight and ride better on the road and on the trail. Plus, you won't be screwing around with twice as many lug nuts and you won't worry about shearing them off (I've seen this happen). I'd go 15s all day any day.

Thanks for the replies, I was trying to look up sidewall strength but didn't see it on the website. Would towing a trailer be a concern with 15's?

The size of the wheel has no bearing on towing.

there is one school of thought that says 15" are getting tougher to get. My buddy is running 15" 35's and they stopped making that size for his brand of tire. He told me this yesterday. I don't know what tire it is but he said he is stuck with 3 good tires and can't find a replacement 4th one.

I know visually I like how 15's and 16's look meatier then 17-18's for the same diameter tires.

@daggo66 - your correct as far as size - I was wondering if there is a sidewall strength difference that I would need to worry about.

@jadmt - didn't think of that, I guess I could keep my 17" stock rims. I always see them listed on craigslist here so I don't think there is a huge local market for selling them. I like the way 33's look on 15" rims as well. Looks beefier.

There is no inherrent issue with the sidewall of a tire with 15" wheels if that is what you are asking. Tires come with different sidewall strengths depending upon the application.

Just keep on mind that 15" rims will not allow room for a big break upgrade such as the one from Teraflex. Need at least 17" wheels to clear the calipers on the bigger rotors. I mention this because you are towing.

You even need to watch backspace with the standard rotors to clear the calipers. IMO, 15" were perfect on TJs and previous generation Jeeps that were smaller but 15's on the JK are a bit undersized. Habits die hard and size matters.
