The tire on the left looks to have a more radical style while the one on the right seem to be a more conservative design. This all seems to be way too political. But seriously folks, I don't have a clue but I couldn't pass up a chance to be a smartass. If I had to guess I'd say the tire on the left still has the new tire nubbies on it so it is the newer tire. So the answer is yes, the Kenda is on the left.
P.S. I didn't vote.
