285 fitment ?

[CAN-03runner]

Guys I've been out of the loop a little bit on 4th Gen mods. So I feel like a newbie again. I did some searching the past few days. But maybe the present thoughts, methods and ideas are different than they were a couple of years ago.

I'd like to now fit a 285/70/17 AT, probably the GY Duratrac, on a 4th gen instead of the 33/12.5/17 MTZ I had, that we're passed on to my newly frankenstiened 1st Gen.

For this fittment I seem to recall that it was possible with an OME lift, and stock wheels provided aftermarket UCA's are installed. Does my memory serve me correct here? Almost all the posts that have come up in my searches indicate 3" lift + 285/70/17 + stock wheels + wheel spacers.

I seen one post that lists the options as wheel spacers OR UCA OR after market wheels.

Can a couple of you guys chime in here. I've been running 33/12.5/17's so i'm already all trimed up and I have LR UCA's. But ran them on a wheel with a little more backspacing. So it is hard to properly guage.

Thanks.

Since you have an OME lift and LR UCA's, all you need are wheel spacers to help fit the 285's with stock wheels.

I thought the only reason you had to have spacers was to clear the uca? I was thinking that with aftermarket ucas you might be able to get by without spacers. Either way, with spacers you would definitely be good to go.

I thought so too but it seems like everyone who runs stock wheels use wheel spacers even with new uca's. :shrug:

:ybrick: Oh why isn't anything ever just bolt and go. So I would need 4 spacers? I was pretty sure the LR UCA would do the trick. Maybe I can buy them and return if not needed.

I would try fitting the 285's and see if they rub the LR uca's. If they do, order some spacers and if they dont, your golden!

You should be good with the LR UCA's. I am running the All Pro UCA's and do not need spacers. A lot of the guys that run them do it for the wider stance look. Also they almost never run 4 spacers and only run them on the front where needed.

I would say the opposite is true...at least for most of the 4th Gen builds.

You should be good with the LR UCA's.

I would be curious to see if the 285s would clear with only LR UCAs as well. I was under the assumption that you needed the slimmer, uniball UCAs. I would be tempted to buy a set vs the spacers if they did clear whenever I upsize to 285/70/17s

I can tell you guys that with the Kelly Safari TSR's (285/70R17's & stock rims), which are identical to the GY Dura's. I put my tires on with just the LR UCA's and mine were like 1/4" to 1/2" from rubbing on the UCA's and that nub that sticks out from the spindle. After I had it aligned and the tires installed I took it out into a dirt field just to see how it did in that soft dirt. I was able to see where the tire tread was rubbing on the LR UCA's. So it was a must for the spacers at that point.

This was mandatory for me!

That's what I figured...the factory backspacing is just too much for 285s to clear without spacers. BTW, do you have any pics of your setup Chayos?

 

[ARK_SWAMP_RIDER]

I think you might be able to get by with a less aggressive 285, definitely looks like spacers are required for duratracs. I just know I remember seeing someone run 285s without spacers on stock wheels.

Here is a link to my flickr account with all my pics. Keep in mind I was having a bit of a rubbing issue, but it was related to how I had my UCA's adjusted. I'm still waiting to get an appointment to get the alignment fixed to stop my front swaybar from rubbing the CO's.



This was prior to my spacers.

True, it may be possible with mainly street driving and a lesser AT like the Destination AT. I do recall seeing a few members posts saying they were running them without spacers too but the only one I remember was 285/70 Nitto TG on SR5 17" wheels. That user claimed no major rubbing despite the TG being a wider tire.

That looks great! Even without the spacers, the 285s seem to eliminate the sucked in look.

IMO, the perfect offset is around +10 to +15...just enough to clear the UCAs and give a slightly wider stance without introducing all the major rubbing on the outside. Unfortunately, there aren't many wheels in this range besides the 17" FJ wheels. Also, A .75" spacer would also be good too. They don't make any high quality, hub centric spacers this size either but one member actually shaved his all-pros and studs.

About the swaybar rubbing the COs, I see you have the rolcate kit installed. I'm surprised it still rubs.

I had 2 goals here with upgrading tires.

1- I am back on 265/65/17 AT with an OME lift. I've sorta gotten used to it, and most people who don't really know don't see anything weird with it, but I do. tall truck - little tires.....

2-For a big part of last year I ran Mickey Thompson 33" MTZ throughout the winter, I never took them off after a winter trail run. And while the handling and stopping was not nearly as good as my 265 yokohama winter tires, the agressive nature of the tire, plus the little extra height was awesome to plow right through snow banks and finding street parking was like never before and I could get all the choice spots...close to my destination where cars and other lesser trucks could not park.

It's toooooo tooooo difficult to go back the 31" after tasting the 33" in the snow, while the MTZ have the LT markings making them legal here, they don't have the mountain/snowflake marking. And they are on my other runner now anyway.

And the GY duratracs look pretty cool and aggressive, have the snowflake symbol, have some sipping, and are an AT so they shouldn't melt away in the summer heat since I would like to keep them year round.

Otherwise, true winter tires like blizzaks have less agressive side walls and may be less likely to run the LR UCA.

Another problem is something something else I read around here somewhere......it went something along the lines of, "a 4Runner tire should never have the words Wrangler written on them".... :lol: Are the duratrac part of the wraggler series?

Wow....everything looks so nice under there. Must be nice not to have winter, snow, ice, slush, SALT!!! in Arizona. Hope your AC doesn't :toilet3: out on you... :lmao:

If i didnt put loctite on the threads, id take a spacer off and see if 285 destinations rub the UCA's.

Ever consider a 265/70/17? You wont have any rubbing on the UCA's and they will fill out the wheel well.

Yes I've considered them, and I was just checking for pricing for the 265/70/17. That tire size would be a good trade off in many respects I think.

-The wheel well fills in a little more
-No rubbing
-half inch less clearance than the 33's but half inch more then the 31"
-the speedometer will be closer to accurate
-I can try to stuff the 32" in the spare tire location under the truck instead of like my 33" in the trunk
-I've towed my 1st Gen offroader with my 31's and and may tow it again, it's probably easier on the truck with the stock 31's than the 33", so 32" is nice happy medium. I'm not sure on this one really if tire size would affect heavy towing. I figure it does since taller tires rob power.
-no extra expense for spidetrax or a new set of rims
-I do still have a set of Mickey Thompson MTZ on the the other 1st Gen 4Runner, that If I really wanted to offroad my 4th gen I can always swap them back out
-I get to use them year round, so I can sell off my 31 inch summer and winter sets.....that finances the new set, which then makes the wife happy, and it reclaims tire storage space for other junk, again the wife is happy
-and a happy wife makes for a happy ME! really I am the man, the king of the castle......

Oh and this was my 100th post. Whoohoo. I'm climbing up there. Whoohoo

Yes Duratrac's are part of the Wrangler series, you could do what I did and get the Kelly Safari TSR's (basically the same tire, as they are made by Goodyear) but they don't say Wrangler and are the same tire for the most part. Plus I bought mine from Treadepot.com, so I only spent $196 a tire plus free shipping.

Seems like you figured it out! 265/70's will be a good choice! Still going with Duratracs?

And most importantly, the wife is happy!! :girl:
