I would think the tracks would do some damage to the wheels since we have such low profile tires. The sides of the tracks really are all that keeps your car going straight through there. I took my previous car through one several times and it always wondered back and forth bouncing off either side. Not to mention the damage it does to your paint. I only took my old car through there because the paint was already done for and those car washes do a really good job of cleaning quickly.I've seen five total in two years in the DFW area - that's it; none in the town I live in - Flower Mound. On a side note - was that a self serve car wash or a full blown one you were at? I'd like to find a non do-it-yourself car wash in DFW, but am concerned about damage (the tracks, etc.)
I take my Fiesta to a coin wash in Grapevine on Dove and W. Northwest Hwy that takes cards because I never actually have quarters. Never use the brush unless you want to scratch the paint, but the pressure washer does a decent job along with a microfiber for the stubborn stuff. I would hand wash with the two bucket method, but I live in an apartment with no access to a hose.
