I’m pretty sure I lost a few lug nut covers at Costco, but when i didn’t first notice the first one gone before leaving they told me after calling them later that they didn’t have them. So now they are all gone and I don’t have to care anymore about them forgetting to put them back on. I figured someone there must be selling them on Ebay. I’m not picky enough to go buy new ones for a 12 year old car.P.S- for our Miata we go to Discount Tire, got rid of the run flats as they were too expensive and gave a rougher ride.
