For sale in SEATTLE: set of 4 Duratracs, local sale only (I can deliver to greater Seattle/Redmond/Bellevue area otherwise you must pick up).
Tires were purchased new 15 months ago (I didn't keep track of how many miles are on them) and now have 16/32 tread depth (new, tread depth was 18/32). The tread has worn very evenly across each tire and is consistent from tire to tire -- no weird wear patterns or anything.
The tires have been rotated religiously every 3000 miles, have never been scuffed against a curb, never had to be plugged or patched, no nails, no slow leaks, etc. They are in excellent condition.
Better mpg's than you will get from 285's.
These tires will fit fine on a non-lifted stock truck.
$600 for the set OBO.
Again, local inquiries only please! Even you are non-local and don't mind paying for shipping, I just don't have time to box them and ship them -- sorry!
PM me if you would like to have a look at them in person.
