I have a set of Kenda tires that came with my bike. they are labed as the Kontender Lite 700x23c.

Last wednesday before a ride i found that my tire was flat, and i asked some of the cycling club members to take a look since I don't know too much about the basic maintenance of my bike..heh. Anyways the tube was folded over (I'm guessing from skidding) inside of the tire, so one of the members gave me an innertube and we were on our way again for the remainder of the ride.

Tonight the same thing happened with the tire! the inner tube wasn't folded over like last week, but there was a leak (last week they checked the inside of the tire before reinstalling it and pumping it up.)

Do you folks have any suggestions to checking whether the tire was installed right? I was told that the rim tape was fine, and last week the tire wasn't pinched so those most likely weren't the issue.

Are Kenda's really this bad? What are your guys' experience with these tires? And if they really are this bad, what tires would you suggest (I just ride from my apartment to class and for a weekly 20 mile ride with the club.)

Thanks!
