Some info to add into the mix on tires.

I just got three new tires from Netzley tire.
On the front, Derick installed two Kumho Solus KH16.
On the rear, a Cooper MASTERCRAFT LSR Grand Touring.

I've only got about 90 miles on them so far.
On the back roads, the Spyder responded much better than with the Kendas.
On the highway at speed, the Spyder handled like it was on rails.

I'm looking forward to the Spyder Clutter in New Holland PA.
