I bought a set of Goodyear ComforTreds from Discount Tire Direct.
Oddly enough, one of the tires had a blemished whitewall (it had black rubber molded into it... which was Goodyear's fault) and the other one had been badly scuffed (like it had been scooted or slid across a rough concrete floor with the whitewall side down... which I would assume was DTD's fault).
I was somewhat annoyed that the tires were blemished, but were shipped to me anyway.
However, one phone call to DTD and it was all taken care of. They issued me a pre-paid UPS shipping label via email, that I printed out and used to ship the tires back, and they shipped out two more tires the same day.
Before I made this purchase, I also had problems with a DTD Support rep that was unaware that this tire had a whitewall. Because of his bad advice, I did not purchase while DTD was offering $100 off of a set of four. A week later, I found out from Goodyear that all of the tires in this size and model were whitewalls, I went back to DTD and asked for them to honor the rebate after it had expired, due to the bad info that I'd received via email. They honored the rebate for me.
I'd likely buy from them again.
