I don't think it's a point of burning them up, more so not being able to stop. Dynatrac just came out with a new big brake kit for the JK which should be available soon and from what I've seen its far better the the teraflex kit.
That being said, if your running a big enough tire you should be running bigger axles which should come with bigger brakes. 35's are fine with factory brakes (I have 40k miles of 35's on my factory brakes plus 10k of factory wheels/tires). 37's are good for some but not for others. With a two door 37's will be much nicer on the brakes then a heavy four door with 37's.
I've been wondering about this issue myself since I swapped axles and increased my tire size. The stock brakes seem a little weak to me and I was wondering if there are brake pads with more stopping power that can be used with the stock calipers. I am not interested in spending a bunch on a complete new system, but better pads are within my budget of they will make a difference. Any suggestions?
Couldn't have said it better. For me personally, I find that running 37's with factory brakes is fine and don't have a problem with them until I drive in a rental car and I near about throw myself out the windshield because I'm braking too hard. I've had a chance to do side by side testing of the new Dynatrac ProGrip vs. other options and can tell you that it really is a big improvement over stock and the competition. It is what I would recommend.
You really need toss some weight around and get them guys producing much faster, lolView attachment 114710
