Spidertrax 1.5" Spacers Are Installed...

What a piece of cake. This installation probably took me about an hour, maybe a little longer, but it sure was simple. Remove wheel, remove any lock rings so that the spacer sits flush, squeeze a little Lock-tite on each spacer lug, torque the lugs to 90 lbs, mount the wheel, then torque each wheel lug to 90 lbs. Done!
Yep, the spacers definitely take care of any rubbing on the control arms at full lock. I was vey impressed with how well constructed they are and how aggressive the stance looks now.

wassup8687 Spidertrax 1.5" spacers and a Terra-flex level kit are both excellent choices. Easy to install and give the Wrangler a much beefier look.

DragonJK Today I had 285/70R17 Duratracs installed on my Billet Silver JKU 'Oscar Mike'.
As soon as I drove away, it was clear that I would need spacers. At full left turn lock, the left tire rubbed. As soon as I got home this afternoon I ordered Spidertrax 1.5" spacers and a Terra-flex level kit.
If you have a JK and purchase Goodyear Duratracs size 285/70R17, just plan on ordering spacers.

56cbr600rr Not true. My 2014 jku with stock wheels and 285/70r17 duratrac rub well before full lock. Maybe each jeep are adjusted differently for full lock... Not sure... What I can tell you though is my jeep with no lift DOES rub. So maybe it's still a good rule of thumb to say spacers or bump stop adjustment may be needed depending on the particular brand of tire you put on.

The real answer is... you do not need to do anything.
My 2013 has 285/70s on the stock wheels without spacers or a lift and the tires do not hit anything. Full lock turn is clear. No need to use spacers there to limit the turn.
The 285/70 is generally just short of 33". About 32.8 or so. This is only a .4" increase on either side of the wheel and is not enough to cause a problem. The increase in width is not enough to cause a problem either with the minimal increase in diameter.
No spacing, no shimming, no trimming as long as you are not planning on extreme disconnected flexing (it doesn't sound to me like you are). If you are then you may need to trim a little off the airdam or simply level your front by lifting 3/4 of a inch or so (looks better anyway).

Casto37 Just throwing this out there...... I just picked up an '08 JKUS. Since it's my DD and I have little kids, I am not up for getting a lift or spacers. I would love to put on a set of Duratrac 285/65/18. Does anyone have any experience with an 18in stock wheel with rubbing?

spiderx Much thanks for the info. I was searching and only found this. Jeep JK Wrangler - Rocker Panel Gaurds - Skid Row Offroad.
That came the closest. Im going to be ordering the ones you got. They are very nice looking. I think it gives it a more finished look to the side of the jeep. And it doesnt stick out either.

They are Rubicon rock rails (Rubi Rails), I forgot where I bought mine from but here is a link to them on quadratech below. I have the OEM Mopar ones but I believe there are other manufacturers out there that make similar ones.

EgoSum After installing the Duratrack 285/70/17 on stock wheels and getting some annoying rubbing against the sway bar, i found the perfect excuse to upgrade whels. Installed the Xd with 4.5 backspacing and now everything is good... Next in the list: a 2.5 lift and sound system upgrade :-)

I'll be interested to see how yours do.

I will likely get the right custom wheels and call it a day. The right set of wheels should clear the 1/4 inch issue.
It really is interesting. I'd gladly take no rubbing! I'll get pictures when i can but it won't be soon unfortunately as I'll be out of town through the weekend.

So the difference between your Duratracs and my Nitto Grapplers is, mine are advertised as 32.8" tall and have a measured tread width of 9.25",
yours are advertised as 33" tall and have a measured tread that is 1/2 inch wider than mine. The Duratrac as it turns out is a slightly larger tire.
That little bit still doesn't seem like it would be a problem if they were on my Jeep with the clearances I've measured, but obviously some minor differences in tire sizes, along with the range of steering movement can make each one it's own case.
I'm not sure that there aren't some minor differences between my 2013 and some of the previous JKs with the steering or something else.
So, although I have room to spare with the 285/70s, I guess the best
advice if you want that size (they are nice) they'll work but be prepared to deal with the possibility of some minor rubbing at full lock. Deal with it meaning... use some washers to limit the range a little or just don't turn the wheel that far...

EgoSum Since it is a minor rub just at almost full lock to the right, and since we wanted to change the wheels eventually, i wonder if wheels with 4" backsacing rathertha the backspace on the stock wheels will resolve the problem for me? I am just 1/4 of an inch too close. Anyone with custom 17 inch wheels and Duratracks 285/70/17? If so what wheels (backspace)?

Cheers,

Even still, the .75" and 1.25" clearances at the swaybar I have at full lock has me wondering if some of these have more turn built into them. I mean even the side that is 3/4" is a long way from rubbing. That isn't even close!
I know some washers as shims to limit the turn to lock can stop the rub. Considering..... how often do you need to go all the way to the stop while turning these things? Mine is a 2-door and it just about pivits on the real wheel as it is.

Miser I'm sure glad that you guys are getting this sorted out. I have a appointment at Discount tire next week to have a set of 285/70r/17 Duratracs installed on my 2013 Rubicon. I have no plans to lift it, or use wheel spacers, because I thought from past threads that they would fit just fine without Mods.
NOW I'M WONDERING IF I SHOULD CANCEL AND STAY WITH MY 255 MTs?
04-23-2013 08:18 PM
cmaggi2 I ran 285/70/17 duratracs for awhile on stock 17" wheels but had minor rubbing. I DO disconnect, but at full turn, I had minor rub not disconnected. I have a 2" lift from using 4 door springs and ended up getting Spidertrax spacers. NO rub when disconnected now.

I run the tires at 31 psi.

The D load range duratracs are softer than stock SR-As. Better ride for me.
04-23-2013 08:10 PM
fireguy I am running 315 70 17 GY Duratracs on the JKU at 30psi and 28 psi on our 04 TJ Rubicon w /265 75 16. The ride is great and the tire performance even better. I have run in dry, wet, black ice and snow / snowpacked conditions and both rigs feel very surefooted. Been off road on loose and sand and they did good also, don't know bout mud or rocks yet though. Impressed with the tires so far.

What is the width of the tread from edge to edge on your Duratracs?
They are listed as 11.5. Still thinking about the spacers but want to avoid the tires sticking out past the fenders. It is close to flush right now and I like that.
04-23-2013 06:38 PM
MacCTD Are the Duratrac 285/70/17s everyone is installing P rated or LTs? The only ones I can find listed on Goodyear's website are LTs.

Marc W Ok, Just out of curiosity I wanted to find out what's going on under there so I had the wife hold the wheel at full lock with the engine running (so it was as far as it could go) and did some measuring.
To start... The tire I have is advertised by Nitto as being 32.8 tall by 11.5 wide.
Goodyear says the Duratracs are 33' tall by 11.5 wide, so your's are a little bigger but not enough to make a difference with the measurements I got.

Here's what I found... turning the wheel to the right, I measured the rear of the right tire at a distance of 1.5" to the frame from the closest part of the tire (plenty of room).
On the other side, the front of the left tire was .75" from the swaybar (much closer).

So for a right turn the closest was 3/4 of a inch at the front of the left tire with 1.5 inches of space at the rear of the right.

Turning the other way (to the left)... the rear of the left tire was a full 2" from the frame and the front of the right tire was 1.25" from the swaybar (tons of room in both places).

So the closest clearance I have is 3/4" at the front of the left tire (to the swaybar)when making a right turn.

That's where you are having a issue so it looks like the problem is that the wheels turn farther to the right than they do when going left.

Duh... I know that sounds goofy but that's what the measurements are saying.

I don't know enough about steering linkage geometry and what's going on here to understand why it would do that or if it's even possible.

Actually the most important thing to consider is... the "wife likes the attitude with spacers"....

I know that you can limit how far your wheels will turn by using washers on the linkage to slightly shorten up the lock to lock. The decrease in turing radius will be so small it won't matter but it will stop the rub. I still think that would be better than spacers to deal with a quarter inch but I don't agree with the spacer danger scenareo the service guy says. That's just CYA speak. Hell if that were true every wheel with a reduced back space would be ruining the axels.
I'm going to go out and measure how much space I have at lock and see if there is any difference side to side. I curious now if maybe the "you may need spacers" could be true due to right/left axel center tollerances when they're built.
lol... if that's the case I'll need to give ESP an appology...
Well, this is a very minimal issue so probably you are right wrt the root cause. I took the air pressure down from 40 psi suggested by DT guys to 33 and i think I am down to 1/8 of an inch or so...in that case the washer trick might work...i would not notice any problem by reducing the turning by 1/8 of an inch and is probably less messy than spacers (install wise) although wife likes the "attitude" of the car with spacers :-)

UPDATE: after two days i found that i might need spacers after all. There is a minimal rubbing when at full lock towards the right. Not towards the left. I measured it and it is just a less than 1/4 inch problem at full lock and the rubbing happens against a bar in the direction. I visited my jeep dealer service manager and he said that i better learn to live with it because a 1.25 inch spacer will ruin the axle and the direction due to excess stress, the car stability, and it would be unsafe in highway driving as a wheel could come off unless i personally dismount each wheel every couple of months and check the torque on the nuts that attach the spacers to the car (he is refering to high quality spacers such as spidertrax)... With so many jeeps out there with spacers, it is hard to believe, but...

It again depends on the tire and the backspacing of the wheel. You cannot assume all 285/70 or 285/75 tires and wheels work without spacers.



Your stating that your tire and wheel combo works. It does but others sometimes don't. You can stand by your statement because it is specifically in regards to your particular tire/wheel combo. It works and it would work for others but people buy different tires and wheels. Each tire is made a little differently depending on the tread and tire width and the wheels they are mounted on. Each wheel in 16x8 or 17x9 "stock sizes" and "aftermarket" feature different backspacing and offsets which can also cause issues.
