This is Part 2 of my review of Gyeon Q² Tire, a ceramic-based tire protectant that claims long-lasting shine, water resistance, and even self-cleaning properties. In this follow-up, I tracked the product’s performance over a two-week period to see how it really holds up.
Recap: First Impressions
To recap, Gyeon Q² Tire is advertised as the first SiO₂-based tire dressing on the market. After initial application, I was impressed by its:
Glossy, wet-looking finish
Minimal sling at first
Clean scent and sleek packaging
However, I had concerns about the pump-style dispenser and thick gel consistency, which made the application tricky and caused streaking and sling—especially after a freeway drive.
What Went Wrong: Over-Application?
After some digging, I discovered Gyeon recommends using 10–15 milliliters for all four tires. In my test, I accidentally used around 10 mL on a single tire, which explains the excessive product buildup, streaking, and sling.
Week 1: Dust and Spread
Within the first week:
The thick coating attracted more dust than usual
The product never fully dried and remained oily to the touch
Over time, it spread into the previously untreated control section
Surprisingly, the tire looked less dusty over time, which may be Gyeon’s “self-cleaning effect” in action—but more testing is needed to confirm that.
Week 2: Fading Shine, But Some Protection
By the second week:
The gloss dulled as expected due to dirt and road grime
From a distance, the tire still looked decent with a darkened shimmer
Close up, it was clear the shine had mostly faded
The Wash Test: Does It Last 6+ Washes?
One of Gyeon’s boldest claims is durability through 6 or more washes. I put that to the test with a quick rinse and light scrub:
Water beaded initially in treated areas—good sign!
But after drying, the tire returned to a yellowish, matte finish
Most of the product had washed away, leaving only a subtle dark tone
Final Thoughts
While Gyeon Q² Tire didn’t fully live up to its long-term promises, it still performed decently:
Pros:
Rich initial shine
Some lasting darkening and water repellency
Easy to clean off when it’s time to reapply
Cons:
Pricey compared to alternatives
Over-application leads to streaking and sling
Shine doesn’t last beyond a few washes
For its cost, Meguiar’s Endurance Tire Gel might offer better value—but I’ll dive into that in a future review.
