New Tires?

So I have been looking and cant find a exact answer to this. I have a 2015 JK Willys W (4 door) that I need to replace the tires on. I just put 285/70 17 Discoverer STT PRO on a new JL Sport with no issues (full stock) and wonder if the same tires will fit on the STOCK JK Willys. the Willys has the stock 17" rims and no lift or leveling kit.


If they will not fit, what spacers would be required to make them fit and what would it do to the amount of tire sticking out from under the Jeep finders?


If it would require too much or would still rub, i may just go with stock size. LT255/75R17 in the same tire

The JL has larger wheel wells and space for the tires.

Height wise the tires will fit, however when you turn you will rub. Adding a 1.5 spacer will eliminate this.

I recommend Spidertrax or Synergy wheel spacers. They are high quality and will not fail on you.

Seem pretty good to me but I only have about 50 miles on them and all on road. the noise level is very acceptable. it is much better than my JK with stock BFG MT. the ride is also better but I don't know if that is JK vs JL or tires. I will be able to answer that question if I put the Coopers on the JK.

So if I am reading correctly, I need to stay with the 255/75 17 if I don't want to add spacers and don't want them to rub. Correct??

the size difference in the 285/70 and the 255/75 is only .5" in height and 1" in width but man it looks like more under the Jeeps...….

What size spacer would be needed? I see 1.375" and 1.5" don't mind the tire sticking out a little but don't want it way out there.

Will spacers affect ride or stress driveline at all?

I'd go 1.5" to clear the rear stock studs. 1.25" require grinding. Not sure if 1.375" will clear.

Stick with a name brand spacer as mention above. You don't want to risk cheap ebay spacers to hold the wheels on your rig.

I've run spacers on my last 2 rigs for almost 80k miles combined and have had zero issues and no abnormal wear of bearings or steering components.

Here's a pic of 285/70s on a stock JL wheel mounted on a JK with 1.5" spacers:

The minimum wheel adapter/spacer you can run on the JK is 1.25". This is due to the length of the wheel studs. Teraflex and a few others have spacers in this size.

I also recommend a 1" spring spacer for the front to get rid of the factory rake and give the proper appearance for running the 285/70's.

Easy to do and functional.

ok, so I am ordering tires today and still have questions as there is a ton of talk about tires and a lot of it seems to conflict.
  1. I read that the Willys W has the same suspension as the Rubi and that 285/70 will fit on a Rubi (stock). is this correct, and if so will they fit a stock Willys W?
  2. These are for my daughters Willys W so it is a "look" more than function as I expect they will spend 95% of the time on the road
  3. I know they will fit with spacers but I want to stay pure stock (no lift, leveling, or spacers)
  4. I have to order them in so I cant just test fit to see what will work.
  5. if they do rub, how bad would it be for daily street driving?

There is no such thing as "Rubicon Suspension". It is the red Rubi shocks and it may or may not have a different spring rate. That's it.

IMO install without the spacers, if it rubs then add them or limit the steering to keep it from rubbing.

A couple of other things;
  • I keep reading that you have to cut the studs for the Teraflex 1.25" spacer, but we didn't have to on the wife's '18. Not sure what year that changed....??....
  • I love the Cooper STT Pro, we put them on her new Jeep and I'm getting a set for mine in the next few weeks.
  • We ran a 1.75" spacer on my wife's old '16 Willys with the factory wheel and a 315/70/17 tire, no issues other than trimming some plastic off the air dam (2.5" lift)
  • We run a 1.25" spacer on her '18 sport with 5" BS wheels and 37/12.5/17 tires and no issues

Pics of both for attention

Good luck!!

I haven't done it yet, we chose to add the spacer instead. I'll let someone chime in that has done it.

Every Jeep is a little different... With the 285/70-17, you are on the fence of needing or not. I suggest a set of 1.25" wheel spacers and a 1" front spring spacer. These are not expensive but will transform the Jeep. The tires will have a much more aggressive stance and the nose will be leveled out giving the "look" you are after.

These would do the trick:

I should have just copied my post from 2 months ago... lol

Seriously, you're about to spend $1000+ on tires and you're agonizing over $100 for a set of spacers? Do it right or stick with the stock tire size...........

it is not a $$ issue. I have seen a lot of negative comments on spacers (even name brand) and it is my daughters Jeep. Risk of spacer failure is just not an option...…

online reviews, in posts here and on other forums. Been doing a bunch of reading trying to figure out if the tires will be ok or not.

I've never seen a spacer that was installed properly fail. Otherwise I would not have installed them on my wife's last 2 Jeeps.

There are plenty of people out there that can screw up anything, and the spacer will get the wrap for it. IMO

I've never heard of a failure with Spidertrax or Synergy spacers. If installed properly, there will be zero issues. They are stronger than the wheel that is mounted to them.

There was a member on here that was in a major wreck. His wheel broke into a million pieces, lost his tire, axle broke etc. Spacer was still mounted to the axle in one piece.

I wouldn't use cheap Ebay or amazon spacers. $160 for a set of Synergy spacers is worth the piece of mind over cheap ass $80 ebay spacers.

All spacers are probably made in one or two factory's in China. I bought a set off of eBay. They were advertised as centric(I think that is the right word) When I put them on they fit perfectly, and all hardware was of good quality. If they didn't fit to my satisfaction then I would of sent them back. If you want to pay almost twice as much for a set because someone stamped their name on them, be my guest. I mean it's pretty hard to screw up something so simple as a CNC'd chunk of aluminum as long as it fits within acceptable tolerances.

Spidertrax are made in the usa.Spidertrax has been providing the off-road market with quality wheel spacers since 1999. With our vehicle specific designs, aluminum anodizing for critical corrosion resistance, and our unmatched competition tested no risk money back guarantee, it's easy to see why Spidertrax Wheel Spacers are the #1 choice among four-wheelers. All Spidertrax Wheel Spacer Kits come complete with 2 6061T6 anodized aluminum wheel spacers, pre-installed wheel studs, lugnuts, and thread locker. Proudly manufactured in the United States of America.

All Spidertrax Wheel Spacers come with an unmatched "competition tested" 30 day money back guarantee and a Limited Lifetime Warranty!

I will gladly pay 2x as much. You can get them for $180 for a set of 4 if you look around and to me that is well worth it.

Here's mine, stock rims and tires, spidertraxx 1.5 spacers and a Mopar 2 inch lift. The spacers push the stock tires slightly past the fenderwell and look great. You won't regret it.
