On my 2014 2 door Sport I am running 315/75/16 Duratracs on 16x8" Summit Racing D Window steel wheels with 4" backspacing. I have full turn lock to lock and haven't experienced any rubbing issues in the front. Factory rear fenders rubbed a lot on compression, actually popped the driver's side rear of a couple of times. All on full stock suspension.



Have since added Hurricane flat fenders and that seems to have solved most of the issues, still do get minor rubbing in the rear, nothing a little bump stop extension wouldn't solve.





Still running the 3.21 gears with an auto, honestly not that bad. But a re-gear to 4.56s is in the works.

 

Guess I can contribute to this thread at the moment, lol -

Trimmed rails earlier in the week, put flat fenders on Friday night, tires mounted Saturday morning (with wheel spacers), and while I've got a 2" lift in queue waiting to be installed...it actually looks kind of proper as it sits now.

Still waiting on bumpers to arrive

 

Cooper stt 35s installed this morning, MC 3.5 ARB tomorrow

 

I know it is probably too early to tell, but how do you like the Cooper STT's?

 

I know your question was directed to Papajohn, but I'll add my 2 cents since I just got rid of my STT's. They were horrible for any road driving. Unbearable noise above 50 MPH, rapid wear, lots of cupping and irregular tread lifting. Maybe I just got a bad batch, but unless you have a dedicated offroad rig, I'd steer clear of the STT's.

 

So far so good, as said they are on the noisy side but i kind of enjoy the hum of an MT on the road, as for wear its way to early to judge but i did lower the air in them just a tad and it rides better.

 

Been running mine for almost 20k miles, through all sorts of road conditions.
I did not find them too loud. Yes, they are louder than stock, but not as bad as the Truxxus M/T I ran on my previous Jeep.
They have good road manners on my JKUR. Handle standing water well, and went through last winter without issue. LOTS of snow, slush, etc.

Not sure how much more life they have. I would assume they are close to 50% now, but they still seem to have plenty of tread left.

 

I couldn't wait for my lift, so I installed new 17 inch level trackers with fierce 12.5x 35 mtr. So far only minor rubbing on sharp turns over depressions in the road.
