Yes, this product is totally safe for both your tires and your wheels. All we recommend is to follow the instructions such as don't use on hot wheels/brake components right after driving, and to give it a good rinsing and drying afterwards.

HOWEVER, if VMR is adamant about not using cleaners, and you are having tough time keeping them clean, I would suggest having a ceramic coating applied. This makes cleaning wheels super easy, sometimes even just a spray of water can clean them. I can't endorse any ceramic coatings, but there are many available and you can just research to see which one best suits your needs.
