Well, I finally got new tires for my 9 year old Swing.
The first place I looked wanted $190 for replacement Hoops and $140 to put them on. That seemed like a lot, especially to have them mounted.
I found some Shinko tires for $80 front and rear at motorcycle-superstore. I added a face shield to get the free shipping for any order over $90. The free shipping was incredible, I got them in less than 24 hours.
I took them to a local shop when they opened Saturday morning. I actually beat the owner there. He said they didn't do tires on Saturday but he'd do them on Tuesday. He charges $35 per tire if you buy the tires from him and $45 if you bring your own. I said okay and left the Swing there. Good thing I have a backup scooter.
He called me in a couple hours and said it was a slow morning so he did them for me, and if I paid cash he wouldn't charge me tax. When I picked it up he said the tires I had were probably the most "nobbly" tires he had ever seen.
So I paid $170 total for two new tires, mounting, balancing and everything. Much better than the $330 the first place wanted.
It pays to shop around.
