I am replacing my wheels/tires at the end of September. I just thought I would throw this out there, to see if anyone wants them, I don't know anything about tires but maybe these will fill a gap before you can purchase ones. They are LoadStar K550 ST175/80 D13 Load rate C They are on my pop up which is stored inside in my garage and has been for the last 9 years, on average we take our pop up out on trips around 4/5 times a year, average 300 miles each round trip. They have a date stamp of 2006 but show no signs of cracks, altho one tire is showing signs of wear (see pics) Again just throwing this out there as I thought I would try and recycle them before I toss them. They can be picked up in the Beaverton/Portland, Oregon area.
