    Hey guys since i picked up my new audi s4 its had brown tires. The cars tires were covered in mud when i was looking at it. The mud must have sat on them for a month or 2. I told them not to pdi it. The following morning i washed off the dirt but there was still a brown layer left on the tire sidewall. Does anyone know what this is or how to get it off? Ill post pics later tonight. Thanks

    Spray Cg grime reaper 4-1 or Meg's super degreaser 4-1. Let it sit for couple minutes(out of sun). Respray and scrub with a brush. Rinse and dry down. Also te brown could of been from a shity tire dressing.

    If its not entirely mud, then it's brake dust. I work in a tire shop and see it all the time. Spray some APC and scrub it down really well. Yu may have to do it a couple times but should clean up

    That definitely sounds more like brake dust. German cars are horrible for it! Previous is correct, APC should take care of it. If not, griots garage makes rubber prep that works quite well.

    Stoner's Tarminator = your friend :) just a light spray on a towel and wipe

    M3ride. Wax on..Wax off

    +1 on the Griot's Rubber Prep that stuff works very well. But like others have mentioned, use a good APC and scrub, scrub, scrub.

    I'd try Mother's wheel and tire cleaner on it, or any tire cleaner that foams up. Spray on, scrub it in, rinse, repeat.

    If this brown discolouration is only on the tyres not the wheel surfaces it could be the tyres in-built protection (Antiozonant)

    Haven't tried tarminator, but I had the same problem and Meg's apc 4:1 helped clean it up.

    The key to tyre dressing durability is deep cleaning the tyre, spray or apply your cleaner allow to soak in for a minute or two and then scrub with a fairly stiff tyre brush, once clean you should be able to take an old white dry terry towel and rub the tyre surface, it should be almost pristine (if not repeat). Tyre cleaner needs to be strong enough to tackle a heavy build-up of tyre dressings, silicone and road grime, but not damage wheel coatings.

    A quality citrus-based cleaner
    (P21S® Total Auto Wash) should clean the tyres down to the original rubber surface, this is especially important when you apply a new dressing, as dressings won't adhere to, or create the right shine on dirty rubber or silicone residue. This tyre cleaner is a strong concentrate; spray-and-rinse, without scrubbing, if you are starting on an old, neglected surface, use a fairly stiff tyre brush for the first application and a spray & rinse at least 3-4 times a year

    Alternative products – Optimum™ Polymer Technologies - Power Clean (diluted 3:1: to 5:1)

    Griot’s Rubber Cleaner and Griot’s Rubber Prep - two excellent products for cleaning rubber; Rubber Cleaner is for regular cleanings; like a car wash for your tires. Then, for more serious cleaning, there’s Rubber Prep, is an intense cleaner for heavily soiled rubber tires, trim, mouldings, seals, and hoses. This gel rubber cleaner removes old dressings and road grime to prepare the surface for a coat of rubber dressing by getting down to the bare rubber

    Just picked up Megs New Foaming All Wheel and Tire Cleaner and this stuff is awesome on both the wheels and tires. Foams up nice and doesn't run. The tires comes so clean you don't even need to dress them. I just cut out APC for tires on my details with this stuff.

    All of the above suggestions will work great too!
