My Kenda’s must be defective. Both of my Spyders have OEM Kenda tires and they both ride smoothly, have good traction, and are problem free.
You might want to be juuust a little wary of gloating about that too much - quite a few who weren't initially having any problems with their Kendas have since discovered to their dismay (and often many wasted $$ looking for alternative causes of their problems) that the Kendas don't necessarily cause issues immediately, but they really do tend to waaaayyyy more often than almost any other tire!
For some, they may never ride hard enough to recognise or bring about any problems, or it might just take them a while before any noticeable issues start to show up; for a very lucky few, they might even get away with running a set of Kendas or even maybe even more than one set of Kenda tires without any major issues appearing! But
very few ever get away with Kendas behaving/working well
all the time; and almost invariably, once these 'former praise singers' eventually
DO swap to just about any other 'real' car tire from the Kendas, they discover how much better performance, traction, ride, handling, etc they were really missing, and even if they don't like to admit it in public, once they've tried some proper tires and become used to running them at the right pressure, they generally end up saying '
Why was I such a denier &/or why didn't I do this sooner?!'
Most will eventually agree that Kendas &/or their clones/derivatives
really do have more failures and problems than just about any other tire they've ever heard of, let alone owned; and
very, VERY few willingly go back to running Kendas after trying just about any 'real' alternative. But I guess there's always gotta be the odd exception just to prove 'the rule'!

So maybe you are that 'lucky' one... or maybe you just haven't found out how bad they really can be -
YET!
