"Bruce" the 2014 Jeep JKUR Build Thread

Yeah, we didn't discuss if they would, or could. I showed them the Jeep, and asked for the 315/70R 17s to be mounted, balanced and installed with road hazard warranty, and they said... "No problem".
The 1.5" wheel adapters had already been mounted before going in.
There were no issues at all.

I think questions raise issues based on cya. Easier to say no sometimes. I tend not to ask questions, keep it simple, professional and concise. Things go smooth. :)

Hope it goes well for you. :beer:

Good point. #cheers

Cheapest price I've found is on Amazon. Free shipping, no tax and 5% off with my Amazon store card. They even have prearranged installation pricing at local tire shops. Gonna give that a try and place the order on next month's billing cycle.

But still debating between 35s and 37-inch KO2s. $200 price difference. Wondering if 37s (35.5 x 12.5") would cause problems on stock rims with Spidertrax Spacers. I'm assuming the gearing wouldn't be any worse than those running Toyos or other true to size 35s with 4.11 gearing. I prefer the heigh to width of the 37. Looks more like a tall and skinny instead of a marshmallow. And is D-rated instead of E. But I worry about it ruining the steering components, braking distances and acceleration. I'm at sea level. So getting anywhere requires driving up a mountain. I'd gladly go with the KM2 but I know that a new one is coming out next year and would rather get the newest tire tech not 8 year old. Just gotta bite the bullet and push down any regrets while I'm not overhauling my axles, brakes and steering.

Well, that is a tough one. My gut would be to follow your heart.
The reason I say this is, if you get what you want you'll rationalize the rest of the upgrades to match.
If you don't get what you want, you won't have that inner smile every time you walk out to the Jeep.

You don't seem the type to push things, or abuse your equipment. I *think* that will buy you time to gather up all the goodies to make it rock solid.

Not trying to be an enabler (for once... lol), but tires are so expensive, and last a long time. What's that saying about the price tag is forgotten...?

That's why I went 33's. That what I needed. Nothing more. 37's would be awesome. But yeah. 33's do the job perfect

I'm sure you've seen my plethora of comments on the 37" KO2 and how perfect it is for the 3.5" AEV and 4.10 gears. Nothing but good things to say about them and I literally live a mile above you elevation wise and consistently took mine up to 12-13k elevation with no issues at all. Gas mileage is better than the stock rubicon tires with 4.10 gears as well. Jeep designed that gearset around people swapping for 35-37" tires.

That's what I'm worried about. Every time if gone smaller than I wanted for the sake of practicality, I've ended up getting the higher thing 6mos later. But I've also gone too far with mods and regretted it.

But there are way more pros in the 35s column.

One thing I hated about my 100-series was how badly it needed a regear. The mountain climb heading west out of green river, Utah had me down to 35mph. The jeep can maintain highway speed up those. Part of that is weight, but the rest is that I'm over geared right now. I don't want to lose that or have to pay to regear since I already paid for the 4.11s.

Aesthetically, I like that my jeep looks lifted with the 3.5 kit. 35s on the 2.5 look stock, as do the 37s on the 3.5 (at least how they fill the wheel wells). 35s with the 3.5 will hopefully achieve the right balance.

Also, everyone I go on trips with drives land cruisers on 33-34" ties or JKURs on 35s with 2.5" lifts. So I shouldn't have any trouble keeping up on the technical sections.

Money wise, the price difference doesn't matter to me. But every platform seems to have a tipping point where you need to start modding to keep up with your other mods. On 100s, it's going to 35s. On JKUs it seems to be 37s. You can do it, but to do it right costs a lot in upgraded gearing, steering, braking, wheels, ball joints, etc. and that's all money that can go toward buying myself a bigger house with a bigger garage. One that fits 78" tall trucks.

Thanks for everyone who's heard me out on this long winded, 2-year tire debate. At this point, anything will look better than stock sized tires.

I have a few trips coming up in the next few months. Lower Sierra traverse, Mexican JT to Moab traverse, and finding some
New routes through Baja Norte. So I'm excited to put the tire debate to bed and move on to preparing for those.

Hopefully the next post will be to show off the new rubber.

Another round of smaller mods are also in the works. Updates to come. And for those concerned I finally got the correct rear bumper bolts and mounted 2/3 of the rear bumper panels. The center and PS are bent and need to be replaced though.

Think of it this way... with the minimum weight difference between the 35" ko2's and the 37' ko2's, as long as you are not "beating" on your jeep, you should be OK. Though my jeep can handle just about anything I toss at it, it really shines on the back road discovery trips I've been on lately. About 5k (damn near all of it offload, as its not my DD) on the 37's, and zero issues. I too live and play way over a mile high, and have not been disappointed with the "performance" aspects of the jeep jumping up to these tires (from the 35" duratracs).

Bottom line, if you beat on it, stuff breaks... regardless of tire size. Treat it with some respect, and she will love you right back ;)

I cannot speak to the long term durability of a JK on 37s, but I will throw out some additional info I've gleaned since picking up Matt's JKUR on 37s.

I've filled the Jeep 3x since acquiring it and it's not gotten less than 17.15 mpg.

1st fill-up - 50% highway/50% city: 17.15
2nd - 40/60: 17.6
3rd - 75/25: 18.18

The first 2 fill-ups split a +5,000 ft elevation gain from the Front Range to Rocky Mtn Nat'l Park. The 3rd fill up was highway driving mostly in excess of 75mph with strong winds and at elevations varying from 5,000 to 6,000 with many 3-5% grades. I didn't buy a JK for fuel economy but I've been pleasantly surprised. I've also been satisfied with acceleration, ability to maintain speed, etc considering the large tires. I had a XJ on 33s w/ 4.56 gears before and the JK is better all around, no surprise.

Do I worry about other consumables fatiguing at a faster rate, absolutely. However, I'm not sure those thoughts would be any less if it were on 35s. Whatever you decide, just do it once and live with it!

See I wasn't lying about mpg :D So happy it's treating you well John! I miss it a lot, but I'm super happy you guys are enjoying it. And I'm waiting for puppy+Jeep pics :)

Since I have the same setup, I can comment and say that It is true...

Think of it this way... The 37's are fairly light for their size, and with the 4.10 gearing (we both have the stock gearing) its acting the same way the 3.43's would on a stock jeep (aka better gas milage, not as great of a low end). Because I have other "go fast" things in my life, I'm OK with the jeep not being a rocket ship...

I didn't hand calculate my last trip, but the EVIC read 16.8 mpg for a trip that included climbing a few highway mountain passes, and lots of back road exploring from 8500 feet to over 13,000 feet :sombrero:

Not to start a fuel mileage war in a build thread... ;)
Depending on quality of gas, and driving speed/habits I can see those #s being realistic.
The important thing is, there is not a substantial decrease such that the "bad ***-ness" is not overcome by the nerve running from the wallet to the brain. :beer:

So... putting my "enabler" hat back on (man it fits good :elkgrin:), Get those 37"s, and don't look back! :victory:
