Thanks for that important, useful information. Here is the issue explained for those with open minds: tire stains
There's a bit more to it than that.
Rubber will absorb petrochemicals - such as asphalt. So if you drive on a newly paved road, the tires will not only pickup some of that asphalt, but some of it will be absorbed by the tire. A tire will not only deposit the excess asphalt onto a garage floor, but some of the absorbed asphalt will too.
All I was trying to say was that something migrated from the tires to the floor. If concrete has the ability to absorb the rubber preservatives, then it might be a good idea to use a barrier.
The sealer that I used is to be applied immediately after the floor is finished. Other types of sealers need curing time before application. Again, this is about effects on the tire, so I mentioned concrete and sealer for more complete information.
Vehicles stored outdoors on concrete may not show the brown stain due to weather cleansing the surface. The asphalt theory may be the problem, I don't know. Since I live in PA where paving is rare so the only newly paved roads are some distance from my home base. I do know that tires get a brown color from the preservatives coming to the surface.
