Default Will 35" Tires Affect Braking Performance?

Right now I am considering wheel options in either 17", 18" or 20" for daily driving on the street and highway. I have a manual 2 dr 09 Rubicon
I know the smaller side walls will reduce some of the body roll, but the increased wheel weight will put more stress on the drivetrain and suspension.
Given the heavier tires and likely heavier wheels I would expect braking distances to increase.
I havent read much about this topic in the forum, so perhaps the difference is tolerable???
Would appreciate your comments.

In my opinion the distance and brake wear is tolerable for aftermarket 17" wheels w/35" tires. Yes, the stopping distance has increased. The more rotational weight you throw in motion, the harder it is to stop.

I've logged 20k+ miles w/35" Toyo MT's and they've seen their fare share of brake to the floor stopping for old lady's who don't look both ways when they pull out of the parking lot...I only worry when it's wet out, never had a problem stopping on dry pavement. Pulled the brake pads to have a look (and clean out mud) they should last at least another 30k miles.

If you're not satisfied with the braking performance w/larger tires Teraflex makes a bolt on big brake kit for a decent price. I'll consider shelling out the $550 for it when I wear these pads out and I'm on 38.5" tires.

Yes, bigger tires will have an impact on braking, as well as all the weight we add to our JK's with heavy bumpers, skid plates, racks, etc. So far I haven't had any problems stopping, but I did notice while towing a U-Haul trailer that the brakes were pretty weak. When my stock pads wear out, I will probably try some upgraded pads like the EBC pads.

Braking performance will decrease . . . by alot in my opinion. Would I drop down in tire size. Not a chance.

The brakes are not that good to start with and no it doesn't get any better going to bigger tires. That being said its not that much different with my 35" Toyo MT than stock. I have had to stand on the brakes a couple of times for quick stops and it did what it had to do. When the ABS kicks in on dry pavement you know you are pushing pretty hard
