I don't know if this is still the case, but Kenda used to be a low-end, low-quality tire. I've only owned one set, at least 15 years ago, and one out of the two was so out-of-round i couldn't ride it. I could feel the bike go up and down as the high spot hit the ground. Certainly it's an unusual problem, but I've never had another tire do that, and I've been riding since the '70s.
There are lots of options in tires these days, and the price difference in the midrange isn't huge. Tires aren't a good place to cut corners if you have an option. Go look in a bike shop.
