kind of going back to this, I just wanted to show you guys a comparison of a water based tire product vs. a jelly/petroleum based product in reference to attracting dirt and such. I did a test where I used Meguiar's hyperdressing on the front 2 wheels, and I used Meguiar's Engurance gel (which is still jelly based, but it's the only jelly based product from my experience that will not turn your tires brown with years of use). I washed the truck this weekend, and we had some snow fall and with snow came the salt on the road. These pictures have been taken after 3 days of driving.
You can see how much more salt and debris were attracted to the tire by the jelly based product. Also, I did not use any product on the tire treads of the rear wheels just to show comparison if no products were used at all
