As to the "cupping" referenced from the OEM Kendas I can attest that both our 15 RT's exhibited this to some degree (I and Discount Tire call it "feathering") which I remediated to some extent by flipping or rotating the tires on the wheels at Discount Tires which were also able to spin balance them and improve the ride and get up to 20,000 miles out of the front Kendas. I ordered and had the Kumho Solus KH fronts in 155/60/15 put on the fronts and now have unidirectional tires/wheels that I can rotate anytime without remounting as required by the directional Kendas.
But, the best news is the wife is Happy, so I'm ecstatic. Just did the north Rim of the Black Canyon of the Gunnison this weekend and while we were blown off by the sport bikes, we were very pleased with their Performance. Hoping for 30,000 miles on the Kumhos similar to the service we seen with the Kumhos rears we've used (2 already mounted, 2- 2016 dated tires in the garage waiting for winter refresh maintenance time):yes::yes::yes:
My tire guy also called it feathering, rather than cupping. He essentially backed up sledmaster's posting and also opined that the recommended air pressure is probably too low, which also leads to feathering. He recommended raising the air pressure up to about 26 psi cold. When I installed my new front tires (Federal) I decided to try his advice. Currently I'm playing with the air pressures and think that 26 is a little too much and makes the front end skittish at times. So far, it seems that 23 psi cold, might be a nice compromise pressure. Time will tell.
