285/70r17 on stock rims
 
I know this is a subject that is beaten dead, but I am looking to run cooper st Maxx on the stock rims is wheel spacers needed? I don't have the factory air dam. And my second question is with 1.5" wheel spacers would they make that size tire stick out past the fender flairs?

Do you plan on going offroad and/or disconnecting at all? If so, you'll probably need spacers. Do you have a lift right now? The tires will probably stick out a little w/ the spacers, yes. I'll try to get a pic during my lunch break...

I would say yes, spacers are needed. I installed 1.5" in prep for going to either 285/70 or slightly bigger...

Here's a pic on 265/70/17 stock wheels, 1.5" spacers. And yes, even these stick out an inch or so past the fenders, 285's will probably be about 2".

I have a teraflex 1.5" performance leveling kit. And I do go offloading occasionally

That looks good with the wider stance. Hmm too bad in mass your tires can't stick out past the fended flairs

I have 285/70/17s, I have not had any issues on stock wheels without spacers. Not currently stock height but I ran them without any lift without issue.

Here's a pic of mine with 285/70/17 duratracs on stock wheels with 1.5 spidertrax no lift. The tires stick out about .75 inch. Personally I like the stance with the spacers and have absolutely no issues.

The tread doesn't, does that make a difference?

285/70r17 trail grapplers with 1.5 spacers: I used to have a side shot to show exactly how much they stick out past the fender but I think I deleted it. Not the greatest pics to show you but maybe they will help:

No lift right now... In the process of deciding what to go with which I am finding really difficult to do.

With the 285's and 1.5 spacers I got slight rub on the air dam at full turn... But just realized you don't have one so you won't have to worry about that.

I run 285-70r17s with no issues-no spacers

Here's my stock height Jeep with stock wheels, 1.5" spacers and 285/70/17 Duratracs:

One of my first set of replacement tires was 285/70/17 MTR's on stock wheels. I didnt think they were rubbing after I first put them on but after having my Jeep in the shop for some mod work, the tech called my back to show me that the tires were rubbing on the sway bars and slowing damaging my tires. I ended up having to get spacers. If you try it without the spacers the quickest way to check on them is look at the sway bar often for rub marks. Here is were mine rubbed.

Thanks for the pictures

I just put a set of 285/70/17s on today and it definitely rubs against the sway bars at full turn. I'm not sure I want to install spacers, even though I think it'll look good with a wider stance. I'm a little concerned about the added stress from installing the spacers. I'm going to install a 2.5 in lift and I hope that'll solve the problem.

DBJeep 09-12-2013 09:02 PM

Spacers create no more stress on bearings or axles than new wheels with different backspacing. Stock wheels with 6" back space and 1.5" spacers put the tires in exactly same place as new wheels with 4.5" backspace. It is the position of the tire patch (or outer edge of the tire in some offroad situations) relative to the bearings that determines the moment loading on the bearings or on the lug bolt studs. Larger diameter tires increase the load on bearings, hubs, spacers, etc during cornering or off camber maneuvers. Wider tires with their necessary spacing modifications also mess with the vehicle steering geometry but generally not where many folks would notice (usually just a little more tire scrubbing on the road during tight turns).

That's interesting. I always research the hell out of things before making a purchase and I'm finding out that sometimes too much info isn't always a good thing. I do like the stance the spacers give and will probably end up purchasing them. If I may ask, what you recommend for a simple 2" lift? I'm looking for the easiest way to do this to hold me off until next season when I plan to move up to 35's and a 4" lift.

My brother in law is running 285/75/17 on 2014 rubicon with an offset on his wheels and no lift and no issues-

If I remember correctly you can put 33s on your rig with a 2" lift. The 285/70/17s is equal to a 32" tire. I'm running 285/70/17s without any lift or spacers. I have a little rubbing right now when I'm in a full turn.

If those tires were put on the stock wheels then you will need spacers for your 2.5 inch lift. Your still going to hit the rim on the suspension with a lift kit. Only way to get away from that is to get aftermarket wheels with 4.5 back spacing or spacers.
