Filthy low-profile tires were not made to be effectively cleaned. Consequentially I am always curious about new tire brushes that become available, so I decided to test out the Gyeon Tire Brush.
I encourage you to read the article, Which Tire Brushes Work For Your Car, in which I break down different tire brush options. Around the time of that article release Gyeon came out with a tire brush similar in specs and purpose as the Tuf Shine Tire Brush. To compare, I have worked with this brush a few times, alternating between it and the Tuf Shine Tire Brush.
In brief, although it is a fantastic cleaning option, I personally did not like it as much as the Tuf Shine Tire Brush.
I certainly do not consider the Gyeon Tire Brush to be ineffective at what it was intended to do. I also believe I can get into the back of a tire more effectively with this brush. I thought the scrubbing action was better with the Tuf Shine (releasing grime better) and the handle is more comfortable to hold.
Due to these highlights, I find myself not using it very much as I do not find that it compares favorably to the Tuf Shine brush. At the same time, it does get the job done. Its appearance serves a purpose at a low price point as a complementary brush. You may have a different product you use to get a tire surgically clean involving scrubbing a different product. Again, this is not a bad brush. I just like the Tuf Shine brush more for my use ergonomics (comfort) and agitation (cleaning action) effectiveness.
