Huge difference in looks

Woah those 392 rims are better looking than the mopar bead lock ones.

Really curious to hear more about your experience with the change in braking feel. Does it take longer to stop? Have your brakes worn out faster? That’s my main issue that’s making me hesitant about getting this size tire

I wouldn’t say I noticed a difference in stopping length, I’m sure there is an increase but not obvious in driving, more of a “heavier” feel when braking and steering. After a day or two you don’t notice anymore, I never think about it now and enjoy how the jeep rides. As far as brake wear I haven’t had to replace yet and I am at about 30K, I imagine driving style and conditions may impact this more.

Mine did. I went from the stock donuts to 285’s. It takes more pedal travel to achieve the same braking force with more noticeable fade (non HD brakes). I got brake effectiveness back by going with Hawk pads and rotors.

It was by no means to the point of loosing trust in the brakes, but there was a noticeable difference in stopping power.

@erickdiaz019 - did the upgraded spare clear the rear bumper?

That’s a fair point, I have the HD brakes that came with the tow package.

Yes, clears with a little room to spare with the K02’s at least

Finally put the 285/70 17s on older rubicon rims.

How is it doing with gas mileage?

Thank you so much for posting this. Lots of good intel. I am looking for wheels and tires for my JLU Sport S.

I wasnt aware HD brakes came as part of the tow package. I have 19 Sport with tow package and pretty sure I don’t have HD brakes as it’s not listed on the sticker. Not sure how to confirm that through on the Jeep itself.

I also have a 2019 Sport with tow package. HD brakes were not included with the tow package. Below is a screen shot of the 2019 order guide.

You are correct, looking back the HD brakes were part of the Optional Equipment Customer Preferred Package 24W, apologies for the confusion.

I’m due for brakes soon anyway and thinking of upgrading to the HD brakes to match up with the 33’s. Are they still available as a kit ?

Honestly, $1700 (on sale) is a bit much for what you get. I’ve had both the basic and HD brakes. Between the basic brakes on 33’s and HD brakes on 31’s there was a noticeable difference, but not substantial. Though, when I did the brakes on my basic JLU with Hawk LTS pads and Hawk Talon front rotors, it perked up braking force to what the HD brakes were. That said, the LTS pads are soft, dirty, and were noisy for a while. The rotors are also soft, and will have to be changed with the pads. IIRC it was $500 for everything front and rear. But that’s $500 each brake job. And that’s still using the smaller rotors with less potential heat dissipation.

I’m on standard brakes with 110 pound 35” KM3’s, and I haven’t had a problem with brake fade, even from highway panic stops, but that’s probably because I’m an idiot and put Hawk Talon drilled/ slotted rotors on the front of a 4x4. Good for street use, but they have the potential to hold mud and reduce brake force on the trail. I haven’t had that though, other than a moment of slip which I’ve felt on any disc brake submerged in water. YMMV.

Given the cost of the Mopar HD brakes ($2400….or $1700 on sale) I’d do the Hawks again. If I felt like spending a couple grand, I’d spend a bit more and get brembo/ wilwood (if you have big wheels) or Teraflex. My next set of axles will be using Teraflex.
