I always have. The reason my 2 other tires have so much tread is a guy on the highway in front of me a few months back had a blowout on his boat trailer and his rim tore about and I got 2 chunks of his rim on 2 tires and had road hazzard cover em free of charge.

 

Not that I'm a fan of them, but check out Ebay for a pair of lightly used tires of the same brand / size to get you by until you can buy 4 matched ones. I bought a single that way once when I couldn;t get a replacement for a bad one with ~10k on the other three and had good luck.

Ok so I went and got tires today from Pep Boys. Futura Scrambler A/P. Out the Door with Road Hazzard was $296.00. Not bad I thought! Now the vibration is gone completely!
