Kumoho tires

I just had my 195/55s put on and noticed within 2 days after I wash my car and use Westleys tire cleaner that the tires look like Herseys chocolate brown. Most tires dont get that bad until they have some age on them and were never dressed.

anyone had any of these tires with this problem. I cant be dressing my tires every 3 days and then have all that crap sling off on my white car.

any ideas gentlemen?

thanks for your help
