choice of tires

I ordered those Douglas tires a few months back. They got three in, but never the fourth, even after reordering them a second time. I did see the three they got in - they were abnormally thin tires. I'm talking squishy, flimsy thin. I cancelled them, went to Discount and got the Sentury house brand tires.

I can't speak to the quality of the Douglas, but I can't imagine them standing up to anything for long beyond gentle driving on smooth pavement.
