I'm going to apologize in advance. I know you guys/girls get these with every new Wrangler owner lol.
Let's start shall we. My name is Marc, I have a new 2014 JKU my first jeep ever. Besides small add ons you know what I want. Tires. Yeah boy.
I have been doing my due diligence and researching (which is how I found you) . I will hold my 15 other questions and start here with two. Any help is very much appreciated and I will send good vibes.
33 inch tires. Safe bet. Smart. You thought I wanted 40 didn't you? I see a lot of 33x12.5 set up on 15 inch wheels.
I like the look. Lots of rubber and has a military look. I don't like the low profile look the younger guys have. My question is by going with the 15 inch wheel aren't you losing ground clearance ? I have the 17 inch sport wheels now, and was considering the 33 on 17s.
At this point you see I have no clue what I'm doing right ?
My second and more easy question is related to the quadratec quadrapac deals. They have a set I like. 33 inch on 15 . With at least 4.5 backspace. (See I have been reading)
But if getting the tire on 17 keeps me higher I want that.
I do plan on a 2.5 " lift. I just need to save for the tires I plan on ordering the lift within a month.
If I can get the tires on without the lift I would .
Which leads me to 5000 other questions but I do not want to harass.
I look forward to speaking to you all.
Tire size is tire size regardless of rim diameter, so 33s on 15" Rims are the same size as 33s on 17" Rims, they will just have more sidewall and since the center of the wheel is identical, so will your ground clearance be.
The biggest concern with smaller diameter rims is clearance for brakes. Not sure if a 15" rim will even be able to clear the brakes on a newer stock JK. I do know that if you ever plan on towing and/or wanting to upgrade your brakes, you'll want at least a 17" rim.

Ground clearance is gained by the height of the tire not the wheel. A 33" tire in a 15" wheel has a larger sidewall than the 17" does. So if you measure from the ground to the top of the tire on both then they will be the same height (or generally so depending on the exact size and tire combo). There for the height from the ground to the bottom of your diff will be the same whether you have a 15" wheel or a 17" wheel.
I'm no expert on 15" wheels but I believe that most steel wheels will not fit without grinding down the caliper. A lot of 15" aluminum wheels do however (pretty sure thats the route that most on this forum go if they want 15s on their JK). Discount tire direct should be able to get you a list of 15" wheels that fit the JK. (likewise qtec maybe able to as well im not sure). Discount is a vendor on this forum.
Not to throw a wrench into your plan but there is always 16" wheels as well.
As far as the lift goes 33's will fit without a lift.

Read a sticky by greenmachine called "So you want bigger tires..."
Also, tire size is constant regardless of rims. Smaller rims = more rubber
It seems 33"s on 15" rims is a popular combo on the forum, lots of folks running this. I am saving up for the same...I am also planning to run a 2.5 " or 3" lift with this and folks are telling me that it's not needed for 33"s. You can get away with a leveling kit or a 1" budget boost with the pucks...I have the Teraflex leveling kit sitting in my Garage that I am going to install in next week or two. Then 33"a and then a bigger lift, maybe.
ProComps seems to be a big brand in 4x4 world, though I have no personal experience with them. Wheels I am eyeing for my 33"a when I get them are ProComps as well...
You guys are fast. I feel silly I should have known the height would be the same.
Now I know why it wasn't covered anywhere. Haha.
Valid points on the caliper clearance I will look into that.
Thanks a lot for taking the time to answer this question I'm sure you have seen it before.
I read the thread mentioned above. It helps also.
I will check into discount.
I'm still stumbling around all the forums.
Came across one questioning the warranty after you lift.
More reason to stay in the 33 range just to play safe. I'm hoping since I'm going up to 33 I'll be pleased (I'm easy to make happy anyway )
But I can surely understand how swapping down could be a bummer .
For sure it would be nice but my commute is 1hr 15m to 1.5hr.
The fuel alone in the stock jeep has hurt. And the payment.
So unless the 33 really look outclassed I better stick there.
However I appreciate the feedback and agree with you
Fixed it for you. Lot's of good info in there, just click the link and soak in the tire and wheel goodness.
15 inch wheels (aluminum or alloy) will usually fit. You can't upgrade to bigger brakes or make some other steering mods but it doesn't sound like you're in the market for such things so no worries.
ProComp tires and wheels are quality from what I can tell but I'm not sure the packages are a good deal. You might be better off looking at Discount Tire Direct. They are on the forum and they offer a discount. There you can probably find a better tire, maybe the Goodyear Duratrac of the BFG AT KO. Both great street tires that are good off road too. They are light too.
I wouldn't go with 35's. They are heavier and while you can run them without a lift, they will rub when the suspension flexes. You can run 33's without a lift and with minimal/no rubbing and they will look good with a 2.5 inch lift if you do that later on. You can always up grade later once the 33's are worn out and you have a better feel for what you want.
