I've used the whole range of products and finally settled on just plain old Armor All. Yes, I know what people say about it but I have never had a tire failure related to sidewall dressing. Now, this doesn't mean I won't have one tomorrow but to date, no issues so far. If applied correctly, it doesn't spin off and gives the tire a low gloss, clean look. If you apply it and it rains, the tires look like garbage but if it has a chance to sit, it lasts for a while.
I usually don't apply any to brand new tires and will only wash them to clean them up for a few weeks anyway. Then, it's Armor All.
