EDIT:
On second thought...I've been using Westley's Bleche White for cleaning tires for as long as I can remember...almost 30 years. That product has always been in my arsenal and always will be, just like the Mothers Cleaner wax paste.
Now, just so happens that not too long ago I found another Mothers product that's worked it's way into a permanent spot in my arsenal...and it too just so happens to clean tires. Mothers foaming all wheel and tire cleaner...it's a great product.
