Pull the tire too late and there is nothing to retread
The decision that determines whether retreading works for a fleet is not which plant or which tread. It is when a tire comes off.
Run a tire down to the point where the casing is exposed to road damage, or keep it in service after the tread has gone, and the casing that was worth money becomes scrap. Pull it while there is still structure to work with and it comes back as a tire.
That decision is made by whoever inspects the units, which is why removal policy belongs in writing rather than in somebody's judgment on the day. A fleet with a clear pull point gets casings back. A fleet without one does not, and usually blames the program.
Where the work happens
Purcell runs seven retread plants and Portland, Oregon serves this region, a short haul by the standards of the network. Monroe is one of 54 Purcell locations collecting casings and handles transport both ways.
The plant runs Monday to Friday, 8:00 AM to 5:30 PM, and Saturday, 8:00 AM to 4:00 PM. No other Purcell plant opens on a Saturday.
Equipment casings are the bigger prize
On a commercial truck tire retreading saves a useful amount. On an OTR tire it saves a great deal more, because the casing represents most of the cost of a very expensive tire and can carry several treads over its life.
Monroe is the only Washington location running mining fleet services, and casing survival is one of the numbers such a program exists to improve. A low rate is about heat, pressure and unrepaired damage rather than about the tires themselves.
What is not retreaded
Tracks. No Purcell plant retreads them, so a worn set is replaced.
About this store
The Monroe store is open Monday to Friday, 7:30 AM to 5:00 PM, managed by JR Webster, and carries all nine Purcell tire categories. Lacey and Renton collect for the same plant.
See the national retreading page for how the program works and for all 54 collecting locations.
