Discontinued Tire Needed!!!

you might try the national or larger regional chains. depending on how long your tires have been unavailable, there might be one in stock somewhere. i recently bought a set of dunlop gt qualifiers in a discontinued size from america's tire. they got them from 3 different stores to get a set of 5.
i wanted a spare for obvious reasons.
here is something to consider, i have recently seen where some tire chains are limiting thier warranty service to 7 years from production date of the tires, even with "lifetime" warranties. they also say NO service after a tire is 10 years old. this was a big o tires store, but they said others are doing it as well, and that it is based on recomendations from the tire mfrs.
good luck, Doug
