I知 Having a Wheel/Tire Dilemma!?!

I cannot decide between 15” with 33x12.5x15 or 16” with 285/75/16. I have read all the tire/wheel threads, but I am looking for pros and cons from members that have experienced this as well.
I realize the 16” package will have a slightly narrower footprint (11.2” vs. the 12.5”), but I am not sure I need all the sidewall I will end up with on the 15” package. I do not plan on rock crawling. Looking for some advice and guidance here thanks…
Oh yeah before I forget I am running a 2012 Sport Base with auto trans, 3.21 gears and S package wheels and tires (255/75/17). And I am getting ready to put on a Rubi JKU take-off suspension 18/59 springs and Rubi Red shocks.

The weight and cost savings of the 33x12.5 would be the decider for me.

my experience... very happy with the 16s. plenty of wheel and tire choices and i personally like the BS on my 16s more than the 15s... you really can't go wrong with either one though...

especially if it's more for looks than function.

personally id go the 16 route. wont stick out as bad and gives you more clearance around the brake caliper. the 11.2 is plenty wide and the extra rolling resistance of the 12.5 would negate any weight savings. if there was any. remember its and inch wider around all 33 inches.

Caliper clearance is fine with a 15x8 wheel and either 3.75" of backspacing or 4.0 of backspacing. Both fit safely and require no modifications. There is no need for more. Larger wheels offer more but there is no need for it unless you are planning on installing much larger aftermarket brakes to go with your 37"-40" tires.

There is a larger foot print but your rational about it off setting the multiple gains in going to a 15" wheel over a 16" isn't true. Tire tread depth, weight, and wheel weight are infinity more important here and are the biggest factors not 1" of tread width. The three I just mentioned are will impact your MPG and power immediately upon mounting to the jeep and hurt your wallet more at the pump. 1" of tread width cannot compare to these other three that are saved by going to a 15" wheel and tire in the same size as the OP is inquiring.

I would go 16, just because 15' is some what being fazed out. it is still readily available but most tire stores locally or at least here do not carry many 15inch tires at all.

the reason i wouldnt run the 15 is because of the backspacing required. 4.25 is good. 3 is too much i want some of the tire under the jeep. and the clearance of the caliper. ive seen rocks get in there and royally screw a caliper and hub up. and alot of it is appearance. 33 12.5 on a 15 looks like a baloon. not a fan. i know thats what you run and im not saying yours doesnt look good. between the two i prefer the 285. just me.

and weight wise there isnt much diff anyway
285 75 16 duratrac 54lbs rim about 18-20lbs depending
33 12.5 15 duratrac 49 lbs rim about 18lbs

total of 20lbs heavier than the 33 but still lighter than the rubicon stockers. i prefer the 16 because i dont like the look of ballons and the back spacing is to much.

This is kind of where I am at as well. I do not like the look of so much sidewall and I was concerned with the caliper clearence being so tight. My off roading is mostly going to be back roads, mountain fire roads and mountain passes, nothing so extreme that I could break something. I do like the idea of the slightly wider stance with the improved back spacing and wider tires.

There are benefits to thinner tires in most conditions except deep snow and deep mud when you want some "float." Just something to consider, though many (but not all) prefer fatter tires.

3.75 backspacing vs the stock 5.75
^^see how far that sticks out. no thanks.


4.5 in back spacing with a 35 x 12.5

and my setup
285s with 5 inch backspacing.



it brings it right to the edge of the fender but not so much all the mud and crap gets thrown inside the door with me and gives it a good stance.

15s being fazed out? 15x8 wheels have been around prior to the 1960s and consistently sell well with no end in sight. By far more popular of a wheel choice than even the stock 17s or 18s. There are many tire choices from every major manufacturer for a 15" wheel. 15" wheels have been the number one choice for YJs and TJs for over two decades and continue strongly with JKs. Almost every maker of wheels produces a 15" alloy that will fit just fine without modification to anything on your JK. Discount Tire is a huge advocate for them and have put together countless threads here on this forum regarding why they are an excellent choice for JKs. This is all fact.

What is also fact is at the end of the day it's entirely up to you and personal choice. Isn't life grand?

OK I decided on the 16" MB Chaos with 4.5" backspacing.

Now I need to decide on which 285/75/16 tire. How do you like those Cooper ATP's? I am conidering between those or the Falken Rocky Mountains...

Thanks

I WENT 16s with 285/75 and I'll never do it again. Too much weight. All those tires are "D" and "E" for heavy duty pickups. They are heavy and expensive. Going with 15" wheels is MUCH better for a Jeep. Second best choice would be to go 17s.

Wheels have already been ordered and are on the way. I wanted the extra caliper clearance that the 15's do not provide. The Cooper ATP's and Falken Rocky Mountains are in the $175 per tire range not that expensive, in the same range of 33x12.5x15. As for weight I will have to wait and see which tire I pick, I know the Falken's are heavy, but I have heard the Coopers are somewhat lighter. My 16" wheels are only 22lbs ea just 1 or 2lbs more than a comperable 15"

Trying to decide between 285/75/16 (33.1") or 295/75/16 (33.4")
If you are using these tires your input would be welcome.

Thanks,

A 17 inch tire will save you about a pound. The wheel will be at least 5 pounds heavier.

Not true. 285/75-16 goes 54-68 lbs. depending on tire. 285/70-17 can be had in P-metric sizes under 50 lbs. That's a big difference. 33s for 15" wheels are upper 40s lbs. Even bigger difference.

I'm comparing the same tire. And 15 inch is not an option for many people due to the low backspace. And no severe winter rating tires in 285/70R17 P-metric (unless you buy winter tires).There is no one size fits all answer

Considering that our Jeeps are designed for extreme off-roading why would some prefer P rated tires rather than LT tires? Wouldn't the P rated tires be more prone to sidewall blowouts/cuts when off road?

Just asking...

Jeep uses P rated tires on every Jeep sold except the Rubicon, which has C rated tires with even lower load capacity. Why ruin the ride and mileage with 1-ton truck tires? I've had one flat on the trail in 17 years and it was my fault.

I know I am breathing life into an old thread that ended back in 2012 so a response could be unlikely. Lee Indy is showing a Rubi with great looking wheels. Anyone know what kind they are? A good blend of not too much black and not too much silver/chrome.

I went with 295/75/16 BFG all terrain KOs and MB 352 wheels with 4.5' backspacing.. Got to say I think I made a good choice.
