Stock 2013 Jeep Wrangler JK with 35″ Tires
One of the more common questions we’re asked is what size of tire can our Flat Style Flares accommodate with a JK’s stock ride height? The internal debate has always been between a 33″x12.50″ and 35″x12.50″ – the 35″ rubbing slightly . The biggest culprit that rubbed the 35’s was the JK’s pinch seam located in the rear wheel well (Forum thread on seam removal). This frivolous extension of the body serves no real function, and can seriously scrape the tread on your tires when articulating.
So we decided to put the 35″ tire theory to the test, and took a stock 2013 Jeep Wrangler Rubicon and threw our Flat Style Flares and 35″x12.5″ KM2 M/T’s on it. Paired with Hanson bumpers – our Rubicon with a stock suspension was ready to tackle the Big Bear Jeep Jamboree!
The first thing we noticed on the 2013 Jeep Wrangler was that the pinch seam was already removed, which was nice, but this required us to trim our Trail Armor Rocker Panel and Mopar rock rail to match.
The Rubicon felt sluggish on the road pulling 35’s with a 4.10 gear ratio, and automatic transmission; although it did manage around 18mpg on the way down. The KM2’s were squishy and would occasionally pull the vehicle off center at highway speeds. Solutions to these problems would be larger gears and an aftermarket drag link/tie rod.
Off Road Performance
The 2013 Jeep Wrangler Rubicon had no issues on the intermediate and advanced trails outside of Big Bear Lake, CA. Its heavy duty NP241J Rock Trac transfer, 4.10 gears, and transmission case turned over the 35″ tires with plenty of low end power to spare.
Despite the Rubicon’s low, stout, stance it had enough wheel travel to get over the major obstacles it faced on the trail. The only signs of rubbing were from smudge marks on the driver side front splash shield. We speculate that the tread of the KM2 M/T’s was just enough to rub, but a 35″x12.50 A/T like Falken’s Wildpeak would clear perfectly.
The 2013 Jeep Wrangler with Bushwacker Flat Style Flares can fit 35″x12.50″ comfortably. With the pinch seam removed on the ’13 JK the only area that can rub is the splash shield if fully articulated.
