I know what you mean about the higher gloss. I used mothers wheel / rim cleaner, and actually used a simonize leather / vinyl cleaner with UV blockers. It gave the tires a nice deep black. Not flat, but definitely not as glossy as the photos. If it works on vinyl, it should be safe on rubber
Doesn't leave an oily or silicone goop to collect dirt. Isn't shiny, just looks like new rubber.
Made to meet Boeing specs for aircraft rubber care. High UV and ozone resistance.
