How are you people getting 10,000 + miles on Kenda tires?
My OEM gave me almost 7,000 mi and Kanine 7,000. They wear in the center. I have lowered the pressure to 24psi, now to 22-23.
I do not hot rod. Almost all of my mileage is highway, solo, but loaded for touring.
I want to go to a car tire but mounting is an issue.
I might add, $450 for a tire and mounting and only get 7,000 miles is outrageous.
@Leroy, please don't do
this ^ to an OEM Kenda or any Kenda clone on the rear of your Spyder -
it's DANGEROUSLY UNDER-INFLATED!! 
The Kendas are tires manufactured with a lightweight construction that
NEEDS the higher pressure specified for them simply to carry the load of your Spyder, and it's that construction that
causes the centre of the tire to throw out during rotation and create the excessive wear,
NOT over-inflation!!
Pretty much no matter how low you drop their pressure, your OEM Kendas/Kenda Clones will
STILL wear out the centre of the tread. So by lowering your OEM KENDA's/KENDA Clone's tire pressures like that,
You are risking catastrophic tire failure due to under-inflation,
which is
not something you do when you lower the pressure on a much stronger constructed 'normal' car tire, which is capable of carrying much greater loads at the pressures the Kenda's/Clone's need just to carry your Spyder, and so they remain still well capable of carrying your Spyder's loads at the lower pressures talked about here!
So please, for your own safety and that of the other road users around you,
DO NOT RUN LOW PRESSURES LIKE THAT IN AN OEM KENDA or KENDA CLONE FITTED TO THE REAR OF YOUR SPYDER! 
In fact, if you've run those 'too low pressures' for anything much more than maybe 100 miles, you've possibly, if not
probably, irreparably damaged the internals of your tire anyway,
and you really should replace it immediately -
this is NOT a joke, nor is the damage anything that can be easily seen until you remove the tire and cut it up to inspect its internals; but having a tire explode and completely disintegrate at any sort of speed due to the sort of damage which is quite likely caused by running those 'too low pressures' in the lightly constructed Kenda's/Clone's, is
really not something you want to experience - many who
do experience this sort of catastrophic tire failure at speed on a motor cycle or trike do not survive!
