Always interesting to meet the sellers behind the ad....
This one pulled the ad after I bought, but before I could copy the ad properly to save it. I saw the wheels for sale and wanted a cheap rim set for a winter bike.
Seller was listing "19 inch wheels" (rims are listed by seller as 19 x 622).
He did say it was hard to find 19 inch tires. I asked him what the numbers meant and he said the wheels are 19 inches tall and 622 around. He also pointed out that the wheels needed more "glue" (I think he meant grease in the hubs).
