I think it's been mention a few times that the brown coloration comes from UV inhibitors that tire manufacturers put in the rubber.

X'2 for ranch.:)

I Just put some megs 40 on them.It seems to get rid of the brown but I don't know for how long.I never had a set of tires turn color like that before.
 
As noted it is a normal occurence, however I do notice it more on the set of Kumhos that I have than other brands. I mostly use PB's BnB as my tire dressing, I don't believe that is the cause for the "excessive" (?) browning.
 
Try scrubbing them with Bleche White first, then us a water based deressing like PB's Bold and Bright, or the new Michelin stuff can be had OTC. The brown is actually the oils and carbon black being drawn from the rubber compound.
 
I've had many sets of kumhos, and have a set on one of my trucks now. I've never had a problem with browning.

Guess your only choice is to keep dressing on them so they look black. That or email kumho and see what they have to say about it.
 
Westley's Bleche White. You can get 32 oz spraybottles at Walmart for $2.72 right now. It makes dirt melt off my tires, and I use oily dressings. I wonder if that would help at all. I use a stiff scrub brush on them.

Correct me if i am wrong,but wouldn't the silicones in the tire dressings cause the tires to brown..

thats the same thing i've always been told, *1 Grand* makes a dressing that i think contains no silicone in it, have to read the bottle again at work, but the dressing does a nice job and isnt suppose to leave tires brown after repeated use
 
I wonder if it has anything to with the model of the tire.These 711's are fairly soft "summer" tire as the call it. since they have less then 500 miles on then I guess I'll have to figure out what works best And hopefully not have to live with brown tires
 
Try Griots Garage Weatherproof Tire Dressing and wear a glove and old clothes. This basically dies the tires black and has no silicone, so it is safe. I used it on my wife's SUV which had the same problem and they've been black for a month now without doing anything to them. In fact, the tires look great after a wash without even putting anything on them. I've got 2 months on my Mercedes tires and again, the tires have a great black matte finish after washing, so I rarely put product on them after a wash.

This stuff is very messy and is basically a stain, so keep that in mind. The sponge they include sucks, so you are better off getting one of the Sonus sponges (the black/red/yellow ones) and use the firm yellow side to apply it.

If it gets on your wheels, wipe it off right away. If you don't, you'll need some 3M Adhesive Remover to get it off, but it will come off very easily with that.
 
Oh, and I forgot to mention that something like Griots Garage Rubber Cleaner with a stiff tire brush is a good product to try first, but based on earlier comments I suspect you'll need the Weatherproof Tire Dressing to get the best results.
 
The Hi-Temp rubber cleaner at Top Of the Line removes the brown bloom perfectly also.
Chances are you'll only have to remove it once because the tire is new and a lot of the uv inhibiting chemicals are on the surface. Once you're removed the surface stuff, they'll leach out much slower in the future.

I have used PB's APC (4:1) Meg's Citri-Gel (1:1), and EO's A2Z (FS) scrubbing with various brushes which I use on tires.

Over the years (decades), I've owned lots of tires from various mfgs. BFG, Cooper, Firestone, Kelly, Michelin, Yokohama (I've probably left someone out). Without question this set of Kumhos (an M+S tire) has the most pronounced case of bloom that I've ever encountered.
