Smokin,
I think you're directing this at Russ, as my lift is in the carport and on concrete. However, since you asked, my tiles are Race Deck. The Race Deck tiles are clearly for show and not much go. A car has no effect on them, but they do not hold up well to a floor jack -- contrary to the manufacturer's claims. The jack wheels dimple the tiles pretty easily. I discovered this last week when we jacked a car on the Race Deck. I really wasn't surprised that there would be some indentations, but the amount of dimpling in several of the tiles was truly disappointing. Granted, the jack used was a cheap small floor jack (<$100), with small wheels. Perhaps a professional model jack with larger wheels and better weight distribution would not have been as tough on the flooring. Obviously, any future jacking will be done with the jack on a thin steel plate. I'll be testing the Race Deck lifetime guarantee on the damaged tiles.
I don't want anyone to get the impression that I'm dissatisfied with the Race Deck flooring. I planned the garage as a showroom and storage, with the carport and its concrete floor as the work area. If I'd wanted to use the garage as a work area, I would have chosen another flooring surface, probably a professionally-applied epoxy. But you can't beat the Race Deck for appearance. In the case of my garage, it's clearly the difference between "That's nice" and "Wow!" Expensive as the Race Deck is, other tile options are even more costly. The Griot's quartz tiles would have cost me $8600 for my 24x24 garage -- over 5 times the cost of the Race Deck and well beyond my modest budget.
