A few months back I bought a pair of Panaracer t-serv 700x28s from a website. Put them on, seemed fine, no problems. I rode them maybe 25 miles before I noticed a bulge on the front tire. Next time I was at the LBS, mentioned it to the owner. He said that it was bad and a manufacturer's defect that should be warrantee-able. I sent the tire back to the online store and they sent a replacement. Unfortunately, the replacement also seems to have a bulge. The original tire that I kept also seems to have a smallish bulge. I've taken them off and inspected the inside and there isn't anything that appears to be a gross/obvious defect. It almost looks like the bulging is a result of the way they sew the tires up (sorry, not a good description). Has anyone else had this problem with these tires (or other Panaracers) ? Should I be worried/send them back? Info/advice please.
