I'm looking at replacing the tires on our 2004 Country Coach tag axle. Currently running Goodyear G661 HSA 12R22.5. I found a Goodyear dealer who has the RSA tires on sale for $388.00 each on sale however when I asked about the date code on the tires he said they were dated February 2019 so they have been sitting in the warehouse for almost a year. So is it a good deal or not? Anyone running these tires?
